wkhtmltopdf Buildpack

This is a Heroku buildpack for bundling a compatible wkhtmltopdf binary with your environment.


  • Buildpack: 0.2
  • wkhtmltopdf: 0.12.5 by default

NOTE: This fork of the buildpack only supports 0.12.5 and higher. It inatalls the deb package for Heroku-18 stack


Add this buildpack to your Heroku application to install the wkhtmltopdf and wkhtmltoimage binaries, and the corresponding library libwkhtmltox, into the dynos:

$ heroku buildpacks:add https://github.com/srbartlett/wkhtmltopdf-buildpack.git

If you want to use a wkhtmltopdf version other than 0.12.3, set WKHTMLTOPDF_VERSION:

heroku config:set WKHTMLTOPDF_VERSION="0.12/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb"

Clearing Repo Cache

Remember to clean your repository cache if you are updating the version of buildpack. To do that, run:

$ heroku plugins:install https://github.com/heroku/heroku-repo.git
$ heroku repo:purge_cache -a appname


If you run into issues when trying to deploy with this buildpack, make sure your app is running on cedar-18

$ heroku stack
