Name
wkhtmltopdf - html to pdf converter
Synopsis
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 contents. The objects are put into the out-
put 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 sec-
tion can only be placed in the global options area.
A page objects puts the content of a single 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 ar-
eas. The applicable options can be found in the Page Options and Headers And Footer Op-
tions sections.
A cover objects puts the content of a single webpage into the output document, the page
does not appear in the table of contents, 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 contents object inserts a table of contents into the output document.
toc [TOC OPTION]...
All options that can be specified for a page object can also be specified for a toc, fur-
ther more the options from the TOC Options section can also be applied. The table of con-
tents is generated via XSLT which means that it can be styled to look however you want it
to look. To get an idea of how to do this you can dump the default xslt document by sup-
plying the --dump-default-toc-xsl, and the outline it works on by supplying --dump-out-
line, see the Outline Options section.

Here are some examples (In case you are unfamiliar with the BNF):
http://user:password@myproxyserver:8080
socks5://myproxyserver
None
Reduced Functionality
This version of wkhtmltopdf has been compiled against a version of QT without the wkhtml-
topdf 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 by using the --page-size option
this can be changed to almost anything else, such as: A3, Letter and Legal. For a full
list of supported pages sizes please see <https://qt-
project.org/doc/qt-4.8/qprinter.html#PaperSize-enum>.
For a more fine grained control over the page size the --page-height and --page-width op-
tions 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
too 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 com-
bined with the arguments given to wkhtmltopdf
For example one could do the following:
echo "https://qt-project.org/doc/qt-4.8/qapplication.html qapplication.pdf" >> cmds
echo "cover google.com https://en.wikipedia.org/wiki/Qt_(software) 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 We-
bKit 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.
