Convert HTML Page To a PDF Using Open Source Tool [ Linux / OS X / Windows ]

D o you need a simple open source cross-platform command line tool that converts web pages and HTML to a PDF file? Look no further, try wkhtmltopdf.

From the project home page:

Simple shell utility to convert html to pdf using the webkit rendering engine, and qt. Searching the web, I have found several command line tools that allow you to convert a HTML-document to a PDF-document, however they all seem to use their own, and rather incomplete rendering engine, resulting in poor quality. Recently QT 4.4 was released with a WebKit widget (WebKit is the engine of Apples Safari, which is a fork of the KDE KHtml), and making a good tool became very easy.

Software features

1. Cross platform.
2. Open source.
3. Convert any web pages into PDF documents using webkit.
4. You can add headers and footers.
5. TOC generation.
6. Batch mode conversions.
7. Can run on Linux server with an XServer (the X11 client libs must be installed).
8. Can be directly used by PHP or Python via bindings to libwkhtmltox.

A note about Debian / Ubuntu Linux user

You can install wkhtmltopdf using apt-get command:
$ sudo apt-get install wkhtmltopdf
$ sudo ln -s /usr/bin/wkhtmltopdf /usr/local/bin/html2pdf

Sample outputs:

Install wkhtmltopdf on MacOS unix

First, install Homebrew on macOS and then type the following brew command:
$ brew install wkhtmltopdf
OR
$ brew cask install wkhtmltopdf

Convert html to pdf with Linux

Written by Guillermo Garron

When you may need to convert a complete web page in html to a pdf file, Linux can help you.

We will need two tools:

• wget — To download the complete page, including css, and others
• wkhtmltopdf — To make the real conversion from html to pdf

You should be able to install both of them using your package manager.

To be able to convert the html to pdf, we will follow a two stage process.

First step, download the web page in html

To do that enter this command:

I will first create a folder to store the page, so.

Then download the web page:

That will create a structure like this:

There you will find the file, new-branch-on-debian-1.html

Second step, convert the html file to pdf file

Enter into the folder where the html file is.

Convert the file.

Using this format

wkhtmltopdf [html file] [pdf file]

That is it, you now have converted a complete html file including format, css, etc. to a pdf file, that you can send by email, archive, or anything you want.

Note: If the page you are downloading does not have .html extension you may get errors, to solve that, just mv (rename) the file to have an .html extension. Now a days, most of the pages does not have .html extensions.

Why do you have static builds with patched Qt?

Good question. Some features require you to use a patched Qt, because those aren’t yet upstream – please read the project status for a longer explanation.

Most Linux distributions (quite understandably) would prefer that this project upstreamed the patches, and choose to compile without those features. This leads to quite different behavior – you get a later web engine, but behavior can vary from distribution to distribution.

Why are there no “generic” Linux builds (which were provided earlier)?

Although the builds are static, it is very important to understand what it means in the context of Qt – on which wkhtmltopdf is built. A static build means that only Qt is linked in this manner – the remaining system packages still need to be installed. Over a period of time, major areas of divergence between distributions were found by trial and error:

• different library versions: not every distribution provides the same versions. This was especially the case for libpng and libjpeg , with a lot of distributions choosing between the 1.2, 1.5 and 1.6 series for the former and multiple versions of libjpeg and/or its fork libjpeg-turbo . While this could be addressed easily by linking them statically (and was actually done so for previous releases) – it broke down when it came to the next point.
• different OpenSSL versions: due to OpenSSL having a bad track record then (it’s better now), distributions started aggressively upgrading their OpenSSL version and disabling unused parts of the library. This led to a situation where there was effectively zero backward compatibility and things started breaking randomly – see #3001 for a very long read of the problems faced. This was the direct motivation to create a separate packaging repository.
• incompatible libc: not every distribution has the same glibc version. If you compile with a later version, it won’t work on a distribution which uses an older version. This was worked around earlier by using CentOS 6 (which had an old enough glibc version). But due to the rise of Docker, the alpine image became very popular. This doesn’t use glibc at all, but the musl libc. So the generic binaries never really worked on Alpine.

While Python has also tried to do this using manylinux – it doesn’t always work well (e.g. alpine is not recommended with binary wheels if you google for it), and requires you to statically link everything. This may work for them, but wkhtmltopdf also depends on the runtime configuration on actual fonts installed (i.e. fontconfig and freetype2 ). It’s not possible to abstract everything out and test/fix everything for every OS/distribution with the limited resources this project has – it makes more sense to make distribution-specific versions which are almost guaranteed to work, as they use the specific versions that the distribution has packaged.

I don’t see an appropriate download for my platform!

If the distribution you are using is listed:

• but not the specific patch release – try it, as it’s very likely to work regardless.
• the major release isn’t listed – we only support LTS versions, so try a LTS version older than your release.
• cannot install package – you can always extract it (google for extract from ), but you’ll need to have the dependencies installed.

Head over to the packaging repository and start a discussion if your platform isn’t listed.

How do I use it with FaaS setups?

You’ll need to extract the distribution-specific package, bundle it with necessary libraries, configuration and/or fonts and then upload it. See this StackOverflow question for Google Cloud Functions. PRs are welcome to expand this section, if you have more information about this – this is not a setup that the maintainer uses 😄

How do I use it in AWS Lambda?

All files required for lambda layer are packed in one zip archive (Amazon Linux 2 / lambda zip). You may test it locally by unpacking the archive into the layer directory and running next commands:

After that, you may find a pdf file generated from the google home page in your layer directory.

To use wkhtmltox in your lambda function you may put the content of the archive together with your lambda function or create a layer. Don’t forget to provide an environment variable for fontconfig ( FONTCONFIG_PATH=/opt/fonts ).

In case you use Serverless framework you may add the next lines to your serverless.yml file:

Symantec reports a virus WS.Reputation.1 for the Windows builds

This is a false positive reported because Symantec has not seen this file before – see this clarification for details.
