wkhtmltopdf — html to pdf converter


wkhtmltopdf [GLOBAL OPTION]... [OBJECT]... <output file>

Document objects

wkhtmltopdf is able to put several objects into the output file, an object is either a single webpage, a cover webpage or a table of content. The objects are put into the output document in the order they are specified on the command line, options can be specified on a per object basis or in the global options area. Options from the Global Options section can only be placed in the global options area

A page objects puts the content of a singe webpage into the output document.

(page)? <input url/file name> [PAGE OPTION]...

Options for the page object can be placed in the global options and the page options areas. The applicable options can be found in the Page Options and Headers And Footer Options sections.

A cover objects puts the content of a singe webpage into the output document, the page does not appear in the table of content, and does not have headers and footers.

cover <input url/file name> [PAGE OPTION]...

All options that can be specified for a page object can also be specified for a cover.

A table of content object inserts a table of content into the output document.

toc [TOC OPTION]...

All options that can be specified for a page object can also be specified for a toc, further more the options from the TOC Options section can also be applied. The table of content is generated via XSLT which means that it can be styled to look however you want it to look. To get an aide of how to do this you can dump the default xslt document by supplying the --dump-default-toc-xsl, and the outline it works on by supplying --dump-outline, see the Outline Options section.

Specifying A Proxy

By default proxy information will be read from the environment variables: proxy, all_proxy and http_proxy, proxy options can also by specified with the -p switch

<type> := "http://" | "socks5://"
<serif> := <username> (":" <password>)? "@"
<proxy> := "None" | <type>? <string>? <host> (":" <port>)?

Here are some examples (In case you are unfamiliar with the BNF):


Reduced Functionality

This version of wkhtmltopdf has been compiled against a version of QT without the wkhtmltopdf patches. Therefore some features are missing, if you need these features please use the static version.

Currently the list of features only supported with patch QT includes:

* Printing more than one HTML document into a PDF file.
* Running without an X11 server.
* Adding a document outline to the PDF file.
* Adding headers and footers to the PDF file.
* Generating a table of contents.
* Adding links in the generated PDF file.
* Printing using the screen media-type.
* Disabling the smart shrink feature of webkit.

Page sizes

The default page size of the rendered document is A4, but using this --page-size optionthis can be changed to almost anything else, such as: A3, Letter and Legal. For a full list of supported pages sizes please see <http://qt-project.org/doc/qt-4.8/qprint…>.

For a more fine grained control over the page size the --page-height and --page-width options may be used

Reading arguments from stdin

If you need to convert a lot of pages in a batch, and you feel that wkhtmltopdf is a bit to slow to start up, then you should try --read-args-from-stdin,

When --read-args-from-stdin each line of input sent to wkhtmltopdf on stdin will act as a separate invocation of wkhtmltopdf, with the arguments specified on the given line combined with the arguments given to wkhtmltopdf

For example one could do the following:

echo "http://qt-project.org/doc/qt-4.8/qappli… qapplication.pdf" >> cmds
echo "cover google.com http://en.wikipedia.org/wiki/Qt_(softwa… qt.pdf" >> cmds
wkhtmltopdf --read-args-from-stdin --book < cmds

Page Breaking

The current page breaking algorithm of WebKit leaves much to be desired. Basically Webkit will render everything into one long page, and then cut it up into pages. This means that if you have two columns of text where one is vertically shifted by half a line. Then Webkit will cut a line into to pieces display the top half on one page. And the bottom half on another page. It will also break image in two and so on. If you are using the patched version of QT you can use the CSS page-break-inside property to remedy this somewhat. There is no easy solution to this problem, until this is solved try organizing your HTML documents such that it contains many lines on which pages can be cut cleanly.
