Create PDFs using plain old HTML+CSS. Uses wkhtmltopdf on the backend which renders HTML using Webkit.


  1. Install wkhtmltopdf (optional) ** PDFKit comes bundled with wkhtmltopdf binaries for Linux i386 and OS X i386 ** PDFKit defaults to user installed versions of wkhtmltopdf if found ** Installing wkhtmltopdf binary *** Download the latest binary from *** Place the binary somewhere on your path (e.g /usr/local/bin)

  2. Install PDFKit

    $ gem install pdfkit


# takes the HTML and any options for wkhtmltopdf
# run `wkhtmltopdf --extended-help` for a full list of options
kit =, :page_size => 'Letter')
kit.stylesheets << '/path/to/css/file'

# Git an inline PDF
pdf = kit.to_pdf

# Save the PDF to a file
file = kit.to_file('/path/to/save/pdf')

# can optionally accept a URL or a File.
# Stylesheets can not be added when source is provided as a URL of File.
kit ='')

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
