PDFKit is a Ruby gem that converts HTML and CSS into PDF documents by wrapping the wkhtmltopdf command-line utility, which renders HTML via WebKit. It accepts HTML strings, files, or URLs, supports stylesheet injection and wkhtmltopdf options, and includes Rack middleware for on-the-fly PDF generation in Rails apps.

Use cases

• generate pdf invoices from html templates in rails
• convert html reports to pdf in ruby
• render a webpage url as a pdf
• serve pdf versions of pages via rack middleware
• create pdfs with custom css stylesheets
• scrape a website and save it as a pdf with cookies

When to choose

• you are building a Ruby or Rails app that needs HTML-to-PDF conversion
• you want simple API wrapping wkhtmltopdf with stylesheet and option support
• you need middleware to automatically serve .pdf URLs from your Rails app

When to avoid

• you need a pure-Ruby solution without external binary dependencies
• wkhtmltopdf is deprecated in your environment and you want a maintained rendering engine like headless Chrome
• you need pixel-perfect modern CSS support beyond WebKit's rendering
• you are not working in Ruby
