WeasyPrint
What it is
WeasyPrint is free, open-source software for web developers who need to turn HTML pages into PDF documents. It accepts HTML, CSS, local files, URLs, file objects, HTML strings, raster images, and SVG. The Python library can render an HTML object with HTML.write_pdf(), while the command-line interface supports PDF/A, PDF/UA, and PDF/X options. Sample outputs include reports, invoices, tickets, books, letters, and posters. WeasyPrint offers an API, fillable form creation, and self-hosted deployment. Documentation covers Linux, macOS, and Windows installation, plus use as a Python library, community Docker images, and an AWS Lambda layer. The default HTTP client does not handle cookies or authentication, although a custom URL fetcher can be supplied. Untrusted HTML or CSS may create security problems. Version 70.0 requires Python 3.10 or later and Pango 1.44 or later. CourtBouillon offers paid assistance, while free and open-source software remains available at no cost.
