What it is and what it does
WeasyPrint is a visual rendering engine that converts HTML and CSS into PDF documents. It is built on Python and designed specifically for pagination and document generation, making it suitable for creating reports, invoices, and tickets from web content. Unlike full browser-based rendering engines, WeasyPrint uses a custom CSS layout engine written in Python, which aims to support web standards for printing.
The package depends on eight runtime libraries including pydyf, cffi, tinycss2, cssselect2, Pillow, fonttools, Pyphen, and tinyhtml5 for PDF generation, C bindings, CSS parsing, image handling, and font management. It supports Python 3.10 and later on both CPython and PyPy, and has been actively maintained since its initial release.
Use it for
- Generate PDF invoices and receipts from HTML templates in e-commerce or billing systems
- Create statistical reports and dashboards as downloadable PDF documents
- Export web pages or HTML content to PDF for archival or distribution
- Build ticket or certificate generation systems that render HTML to PDF
- Convert HTML-based forms or documents to print-ready PDF files
