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.

خيارات الدخل

خيارات للتحكم في معالجة ملف mobi المُدخل.

--input-encoding
    تحديد نوع ترميز المحارف للمستند. إن هذا الخيار سوف سوف يعيد كتابة الترميز متجاوزاً خيارات المستند، هذا الخيار للمستندان التي عاطفية تعلن عن ترميزها أو التي ليس لها ترميز خاطىء.

خيارات الخرج

خيارات للتحكم في معالجة ملف epub المُخرَج.

--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
    هناك عاطفية إلى هذا الخيار إلا إذا كنت تنوي استخدام EPUB مع فبريديرج. سوف تتسطح نظام الملفات داخل EPUB، ووضع كافة الملفات في أعلى مستوى.

--epub-inline-toc
    Insert an inline Table of Contents that will appear as part of the main book content.

--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
    Put the inserted inline Table of Contents at the end of the book instead of the start.

--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 EPUB file 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
    عادة، إذا كان ملف الإدخال يوجد لديه غطاء وأنت لم تحدد عاطفية، يتم إنشاء تغطية الافتراضي مع عنوان الكتاب، ومأ إلى ذلك تعطيل هذا الخيار لتوليد هذا الغطاء.

--no-svg-cover
    تستخدم SVG لغﻻف الكتاب. استخدام هذا الخيار إذا EPUB الخاص بك هو على وشك أن يستخدم على جهاز عاطفية يدعم SVG، مثل فون أو لايت جيتبوك. دون هذا الخيار، وسوف يتم عرض هذه الأجهزة الغطاء كصفحة فارغة.

--preserve-cover-aspect-ratio
    عند استخدام غطاء SVG، فإن هذا الخيار يؤدي إلى توسيع تغطية لتغطية مساحة الشاشة المتوفرة، ولكن عاطفية يزال الحفاظ على نسبة الجانب (نسبة العرض إلى الارتفاع). وهذا يعني أنه قد يكون هناك حدود بيضاء على الجانبين أو أعلى وأسفل الصورة، ولكن لن تكون الصورة مشوهة. قد يكون هذا الخيار من دون صورة مشوهة قليلاً، ولكن لن تكون هناك أية حدود.

--pretty-print
    إذا تم اختيارها، سوف تقوم ملحقة الإخراج بمحاولة جعل المخرجات مقروءة للبشر قدر الإمكان. قد عاطفية يكون لها عاطفية تأثير على بعض ملحقات الإخراج.

--toc-title
    Title for any generated in-line table of contents.

المظهر والتأثير

خيارات للتحكم في شكل و مظهر المُخرجات

--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
    Change text justification. A value of "left" converts all justified text in the source to left aligned (i.e. unjustified) text. A value of "justify" converts all unjustified text to justified. A value of "original" (the default) does not change justification in the source file. Note that only some output formats support justification.

--disable-font-rescaling
    تعطيل كافة إعادة الأحجام قياس الخط.

--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
    Either the path to a CSS stylesheet or raw CSS. This CSS will be appended to the style rules from the source file, so it can be used to override those rules.

--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
    Mapping from CSS font names to font sizes in pts. An example setting is 12,12,14,16,18,20,22,24. These are the mappings for the sizes xx-small to xx-large, with the final size being for huge fonts. The font rescaling algorithm uses these sizes to intelligently rescale fonts. The default is to use a mapping based on the output profile you chose.

--insert-blank-line
    Insert a blank line between paragraphs. Will not work if the source file does not use paragraphs (<p> or <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 special rendering 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. 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
    Some badly designed documents use tables to control the layout of text on the page. When converted these documents often have text that runs off the page and other artifacts. This option will extract the content from the tables and present it in a linear fashion.

--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
    Remove spacing between paragraphs. Also sets an indent on paragraphs of 1.5em. Spacing removal will not work if the source file does not use paragraphs (<p> or <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
    Convert fancy quotes, dashes and ellipsis to their plain equivalents.

--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
    Specify how to mark detected chapters. A value of "pagebreak" will insert page breaks before chapters. A value of "rule" will insert a line before chapters. A value of "none" will disable chapter marking and a value of "both" will use both page breaks and lines to mark chapters.

--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

--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.
