ebook-convert input_file output_file [options]
Convert an e-book from one format to another.
input_file is the input and output_file is the output. Both must be specified as the first two arguments
to the command.
The output e-book format is guessed from the file extension of output_file. output_file can also be of
the special format .EXT where EXT is the output file extension. In this case, the name of the output file
is derived from the name of the input file. Note that the filenames must not start with a hyphen.
Finally, if output_file has no extension, then it is treated as a folder and an "open e-book" (OEB)
consisting of HTML files is written to that folder. These files are the files that would normally have
been passed to the output plugin.
After specifying the input and output file you can customize the conversion by specifying various
options. The available options depend on the input and output file types. To get help on them specify the
input and output file and then use the -h option.
For full documentation of the conversion system see E-book conversion
Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation
marks. For example: "/some path/with spaces"
The options and default values for the options change depending on both the input and output formats, so
you should always check with:
ebook-convert myfile.input_format myfile.output_format -h
Below are the options that are common to all conversion, followed by the options specific to every input
and output format.

--input-profile
Vælg input-profil. Input-profilen vejleder systemet i hvorledes forskellig information i
input-dokumentet skal tolkes. F.eks. opløsningsafhængige længder (f.eks. pixel-længde).
Valgmuligheder er: cybookg3, cybook_opus, default, hanlinv3, hanlinv5, illiad, irexdr1000,
irexdr800, kindle, msreader, mobipocket, nook, sony, sony300, sony900
--list-recipes
List builtin recipe names. You can create an e-book from a builtin recipe like this: ebook-convert
"Recipe Name.recipe" output.epub
--output-profile
Specify the output profile. The output profile tells the conversion system how to optimize the
created document for the specified device. In some cases, an output profile can be used to
optimize the output for a particular device, but this is rarely necessary. Choices are:cybookg3,
cybook_opus, default, generic_eink, generic_eink_large, generic_eink_hd, hanlinv3, hanlinv5,

INPUT VALGMULIGHEDER
Valgmuligheder til styring af behandlingen af input mobi filen
--input-encoding
Angiv tegnsættet for kildedokumentet. Hvis denne indstilling vælges, vil dokumentets tegnsætsvalg
overskrives. Især nyttig til dokumenter, hvor tegnsæt ikke er valgt eller har fejlagtige
tegnsætsvalg.
OUTPUT VALGMULIGHEDER
Valgmuligheder til styring af behandlingen af output epub
--dont-split-on-page-breaks
Turn off splitting at page breaks. Normally, input files are automatically split at every page
break into two files. This gives an output e-book that can be parsed faster and with less
resources. However, splitting is slow and if your source file contains a very large number of page
breaks, you should turn off splitting on page breaks.
--epub-flatten
This option is needed only if you intend to use the EPUB with FBReaderJ. It will flatten the file
system inside the EPUB, putting all files into the top level.
--epub-inline-toc
Indsæt en indholdsfortegnelse som vil blive vist som en del af bogens indhold.
--epub-max-image-size
The maximum image size (width x height). A value of none means use the screen size from the output
profile. A value of profile means no maximum size is specified. For example, a value of 100x200
will cause all images to be resized so that their width is no more than 100 pixels and their
height is no more than 200 pixels. Note that this only affects the size of the actual image files
themselves. Any given image may be rendered at a different size depending on the styling applied
to it in the document.
--epub-toc-at-end
Indsæt indholdsfortegnelsen i enden af bogen istedet for ved begyndelsen.
--epub-version
The version of the EPUB file to generate. EPUB 2 is the most widely compatible, only use EPUB 3 if
you know you actually need it.
--extract-to
Extract the contents of the generated book to the specified folder. The contents of the folder are
first deleted, so be careful.
--flow-size
Split all HTML files larger than this size (in KB). This is necessary as most EPUB readers cannot
handle large file sizes. The default of 260KB is the size required for Adobe Digital Editions. Set
to 0 to disable size based splitting.
--no-default-epub-cover
Normalt, hvis input-filen ikke har et omslag og du ikke angiver et, vil et standard omslag
genereres med titel, forfattere, osv. Denne valgmulighed deaktiverer genereringen af dette omslag.
--no-svg-cover
Anvend ikke SVG (Scalable Vector Graphics) til et e-bogomslag. Anvend denne valgmulighed hvis din
EPUB skal anvendes til en enhed som ikke understøtter SVG, som f.eks. iPhone eller JetBook Lite.
Uden dette fravalg vil disse enheder blot vise omslaget som en blank side.
--preserve-cover-aspect-ratio
Når et SVG omslag anvendes, vil denne valgmulighed gøre at omslaget skaleres til skærmstørrelsen,
men stadig bevare aspektforholdet (forholdet mellem bredde og højde). Dette betyder at der kan
forekomme hvide flader ved siderne eller top og bund af illustationen, men det forvrænges. Uden
denne valgmulighed vil billedet i en del tilfælde blive forvrænget, men skærmen vil fyldes ud.
--pretty-print
Hvis angivet, vil uddata-udvidelsesmodulet prøve at oprette uddata, der er så læsbart som muligt.
Vil muligvis ikke have virkning for visse uddata-udvidelsesmoduler.
--toc-title
Title for any generated inline table of contents.
UDSEENDE OG OPFØRELSE
Valgmuligheder til styring af udseendet af output
--asciiize
Transliterate Unicode characters to an ASCII representation. Use with care because this will
replace Unicode characters with ASCII. For instance it will replace "Pelé" with "Pele". Also, note
that in cases where there are multiple representations of a character (characters shared by
Chinese and Japanese for instance) the representation based on the current calibre interface
language will be used.
--base-font-size
The base font size in pts. All font sizes in the produced book will be rescaled based on this
size. By choosing a larger size you can make the fonts in the output bigger and vice versa. By
default, when the value is zero, the base font size is chosen based on the output profile you
chose.
--change-justification
Vælg afsnitsjustering. "left" giver venstremargin. "justify" giver lige margin. "original"
(standard) - ingen ændring. Bemærk at kun nogle output-formater understøtter lige margin.
--disable-font-rescaling
Deaktivér alle reskaleringer af skriftsstørrelser
--embed-all-fonts
Embed every font that is referenced in the input document but not already embedded. This will
search your system for the fonts, and if found, they will be embedded. Embedding will only work if
the format you are converting to supports embedded fonts, such as EPUB, AZW3, DOCX or PDF. Please
ensure that you have the proper license for embedding the fonts used in this document.
--embed-font-family
Embed the specified font family into the book. This specifies the "base" font used for the book.
If the input document specifies its own fonts, they may override this base font. You can use the
filter style information option to remove fonts from the input document. Note that font embedding
only works with some output formats, principally EPUB, AZW3 and DOCX.
--expand-css
By default, calibre will use the shorthand form for various CSS properties such as margin,
padding, border, etc. This option will cause it to use the full expanded form instead. Note that
CSS is always expanded when generating EPUB files with the output profile set to one of the Nook
profiles as the Nook cannot handle shorthand CSS.
--extra-css
Enten stien til en CSS stylesheet eller rå CSS. Dette CSS vil blive tilføjet til stilreglerne fra
kildefilen, så de tilsidesætte de oprindelige stilregler.
--filter-css
A comma separated list of CSS properties that will be removed from all CSS style rules. This is
useful if the presence of some style information prevents it from being overridden on your device.
For example: font-family,color,margin-left,margin-right
--font-size-mapping
Afbildning fra CSS skriftsnavne til skriftsstørrelser i pkt (typografiske punkter). Et eksempel
valg er 12,12,14,16,18,20,22,24. Disse afbildninger er skriftsstørrelserne for xx-small til
xx-large, med den sidste størrelser for store skriftsstørrelser. Skrifternes reskaleringsalgoritme
anvender disse størrelser som målestok. Standardværdien fås fra en output-profil du tidligere har
valgt.
--insert-blank-line
Håndhæv blank linje (=to linjeskift) mellem afsnit. Valget har ikke effekt på kildefiler, som ikke
indeholder <p> eller <div> tags.
--insert-blank-line-size
Set the height of the inserted blank lines (in em). The height of the lines between paragraphs
will be twice the value set here.
--keep-ligatures
Preserve ligatures present in the input document. A ligature is a combined character of a pair of
characters like ff, fi, fl et cetera. Most readers do not have support for ligatures in their
default fonts, so they are unlikely to render correctly. By default, calibre will turn a ligature
into the corresponding pair of normal characters. Note that ligatures here mean only unicode
ligatures not ligatures created via CSS or font styles. This option will preserve them instead.
--line-height
The line height in pts. Controls spacing between consecutive lines of text. Only applies to
elements that do not define their own line height. In most cases, the minimum line height option
is more useful. By default no line height manipulation is performed.
--linearize-tables
Nogle dårligt designede dokumenter anvender tabeller til layout-styring af sidens tekstelementer.
Når disse dokumenter konverteres, har de ofte tekstelementer som løber ud af skærmen eller andre
mærkværdigheder. Dette valg vil fjerne tabellen og sammensætte tekstelementerne i læserækkefølge.
--margin-bottom
Set the bottom margin in pts. Default is 5.0. Setting this to less than zero will cause no margin
to be set (the margin setting in the original document will be preserved). Note: Page oriented
formats such as PDF and DOCX have their own margin settings that take precedence.
--margin-left
Set the left margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to
be set (the margin setting in the original document will be preserved). Note: Page oriented
formats such as PDF and DOCX have their own margin settings that take precedence.
--margin-right
Set the right margin in pts. Default is 5.0. Setting this to less than zero will cause no margin
to be set (the margin setting in the original document will be preserved). Note: Page oriented
formats such as PDF and DOCX have their own margin settings that take precedence.
--margin-top
Set the top margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to
be set (the margin setting in the original document will be preserved). Note: Page oriented
formats such as PDF and DOCX have their own margin settings that take precedence.
--minimum-line-height
The minimum line height, as a percentage of the element's calculated font size. calibre will
ensure that every element has a line height of at least this setting, irrespective of what the
input document specifies. Set to zero to disable. Default is 120%. Use this setting in preference
to the direct line height specification, unless you know what you are doing. For example, you can
achieve "double spaced" text by setting this to 240.
--remove-paragraph-spacing
Fjern afstand mellem afsnit. Der vælges også et indryk på 1,5em. Spacing removal will not work if
the source file does not use paragraphs Valget har ikke effekt på kildefiler, som ikke indeholder
<p> eller <div> tags.
--remove-paragraph-spacing-indent-size
When calibre removes blank lines between paragraphs, it automatically sets a paragraph indent, to
ensure that paragraphs can be easily distinguished. This option controls the width of that indent
(in em). If you set this value negative, then the indent specified in the input document is used,
that is, calibre does not change the indentation.
--smarten-punctuation
Convert plain quotes, dashes and ellipsis to their typographically correct equivalents. For
details, see https://daringfireball.net/projects/smartypants.
--subset-embedded-fonts
Subset all embedded fonts. Every embedded font is reduced to contain only the glyphs used in this
document. This decreases the size of the font files. Useful if you are embedding a particularly
large font with lots of unused glyphs.
--transform-css-rules
Path to a file containing rules to transform the CSS styles in this book. The easiest way to
create such a file is to use the wizard for creating rules in the calibre GUI. Access it in the
"Look & feel->Transform styles" section of the conversion dialog. Once you create the rules, you
can use the "Export" button to save them to a file.
--transform-html-rules
Path to a file containing rules to transform the HTML in this book. The easiest way to create such
a file is to use the wizard for creating rules in the calibre GUI. Access it in the "Look &
feel->Transform HTML" section of the conversion dialog. Once you create the rules, you can use the
"Export" button to save them to a file.
--unsmarten-punctuation
Konverter dekorative citater, bindestreger og ellipse til deres almindelige ækvivalenter.
HEURISTISK BEHANDLING
Modify the document text and structure using common patterns. Disabled by default. Use
--enable-heuristics to enable. Individual actions can be disabled with the --disable-* options.
--disable-dehyphenate
Analyze hyphenated words throughout the document. The document itself is used as a dictionary to
determine whether hyphens should be retained or removed.
--disable-delete-blank-paragraphs
Fjern tomme afsnit fra dokumentet, når de eksisterer mellem hvertandet afsnit
--disable-fix-indents
Turn indentation created from multiple non-breaking space entities into CSS indents.
--disable-format-scene-breaks
Left aligned scene break markers are center aligned. Replace soft scene breaks that use multiple
blank lines with horizontal rules.
--disable-italicize-common-cases
Søg efter almindelige ord og mønstre der angiver kursiveret tekst og kursiver dem.
--disable-markup-chapter-headings
Detect unformatted chapter headings and sub headings. Change them to h2 and h3 tags. This setting
will not create a TOC, but can be used in conjunction with structure detection to create one.
--disable-renumber-headings
Looks for occurrences of sequential <h1> or <h2> tags. The tags are renumbered to prevent
splitting in the middle of chapter headings.
--disable-unwrap-lines
Unwrap lines using punctuation and other formatting clues.
--enable-heuristics
Slå heuristisk behandling til. Dette skal være slået til for heuristisk behandling kan finde sted
overhovedet.
--html-unwrap-factor
Scale used to determine the length at which a line should be unwrapped. Valid values are a decimal
between 0 and 1. The default is 0.4, just below the median line length. If only a few lines in
the document require unwrapping this value should be reduced
--replace-scene-breaks
Replace scene breaks with the specified text. By default, the text from the input document is
used.
SØG OG ERSTAT
Ændre dokumentets tekst og struktur vha. brugerdefinerede mønstre.
--search-replace
Path to a file containing search and replace regular expressions. The file must contain
alternating lines of regular expression followed by replacement pattern (which can be an empty
line). The regular expression must be in the Python regex syntax and the file must be UTF-8
encoded.
--sr1-replace
Erstatning som skal erstatte teksten fundet med sr1-search.
--sr1-search
Søgemønster (regulært udtryk) som skal erstattes med sr1-replace.
--sr2-replace
Erstatning som skal erstatte teksten fundet med sr2-search.
--sr2-search
Søgemønster (regulært udtryk) som skal erstattes med sr2-replace.
--sr3-replace
Erstatning som skal erstatte teksten fundet med sr3-search.
--sr3-search
Søgemønster (regulært udtryk) som skal erstattes med sr3-replace.
STRUKTURDETEKTERING
Styring af auto-detektion af dokumentets struktur.
--add-alt-text-to-img
When an <img> tag has no alt attribute, check the associated image file for metadata that
specifies alternate text, and use it to fill in the alt attribute. The alt attribute improves
accessibility by providing text descriptions for users who cannot see or fully interpret visual
content.
--chapter
An XPath expression to detect chapter titles. The default is to consider <h1> or <h2> tags that
contain the words "chapter", "book", "section", "prologue", "epilogue" or "part" as chapter titles
as well as any tags that have class="chapter". The expression used must evaluate to a list of
elements. To disable chapter detection, use the expression "/". See the XPath Tutorial in the
calibre User Manual for further help on using this feature.
--chapter-mark
Angiv hvordan detekterede kapitler skal fremhæves. Værdien "pagebreak" vil indsætte sideskift før
kapitler. Værdien "rule" vil indsætte et linjeskift før kapitler. Værdien "none" vil deaktivere
fremhævningen - og værdien "both" vil bruge både sideskift og linjeskift som kapitelfremhævning.
--disable-remove-fake-margins
Some documents specify page margins by specifying a left and right margin on each individual
paragraph. calibre will try to detect and remove these margins. Sometimes, this can cause the
removal of margins that should not have been removed. In this case you can disable the removal.
--insert-metadata
Insert the book metadata at the start of the book. This is useful if your e-book reader does not
support displaying/searching metadata directly.
--page-breaks-before
An XPath expression. Page breaks are inserted before the specified elements. To disable use the
expression: /
--prefer-metadata-cover
Brug omslaget fra kildefilen fremfor det angivne omslag.
--remove-first-image
Remove the first image from the input e-book. Useful if the input document has a cover image that
is not identified as a cover. In this case, if you set a cover in calibre, the output document
will end up with two cover images if you do not specify this option.
--start-reading-at
An XPath expression to detect the location in the document at which to start reading. Some e-book
reading programs (most prominently the Kindle) use this location as the position at which to open
the book. See the XPath tutorial in the calibre User Manual for further help using this feature.
INDHOLDSFORTEGNELSE
Styring af den automatiske generering af indholdsfortegnelsen. Som udgangspunkt vil en evt.
indholdsfortegnelse i kildefilen blive foretrukket, fremfor en selvgenereret.
--duplicate-links-in-toc
When creating a TOC from links in the input document, allow duplicate entries, i.e. allow more
than one entry with the same text, provided that they point to a different location.
--level1-toc
XPath expression that specifies all tags that should be added to the Table of Contents at level
one. If this is specified, it takes precedence over other forms of auto-detection. See the XPath
Tutorial in the calibre User Manual for examples.
--level2-toc
XPath expression that specifies all tags that should be added to the Table of Contents at level
two. Each entry is added under the previous level one entry. See the XPath Tutorial in the calibre
User Manual for examples.
--level3-toc
XPath expression that specifies all tags that should be added to the Table of Contents at level
three. Each entry is added under the previous level two entry. See the XPath Tutorial in the
calibre User Manual for examples.
--max-toc-links
Maksimalt antal isatte henvisninger i indholdsfortegnelsen. Vælg 0 for deaktivering. Standardværdi
er: 50. Henvisninger tilføjes kun til indholdsfortegnelsen hvis mindre end kapitelantal tærsklen.
--no-chapters-in-toc
Tilføj ikke auto-detekterede kapitler til indholdsfortegnelsen.
--toc-filter
Fjern indgange i indholdfortegnelse med titler, der matcher det valgte regulære udtryk. Matchende
indgange og alle deres underindgange fjernes.
--toc-threshold
Hvis færre end dette antal kapitler er genkendt, bliver henvisninger tilføjet til
indholdsfortegnelsen. Standardværdi: 6
--use-auto-toc
Hvis kildefilen allerede har en indholdsfortegnelse, vil den normalt blive anvendt i stedet for
den auto-genererede. Med denne indstilling vil den auto-genererede altid blive brugt.
