CairoSVG
A Simple SVG Converter based on Cairo
Decision gist · record as of 2026-08-14
Yes. CairoSVG is production-stable, actively maintained, has low install friction, no known vulnerabilities, and solves a concrete problem (SVG conversion to multiple formats). The LGPL copyleft license is standard for graphics libraries and poses no barrier for most use cases. Install if you need reliable SVG-to-PDF/PNG/EPS conversion.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; Cairo graphics library must be available on the system (typically pre-installed on most Linux distributions, may require separate installation on macOS or Windows).
- Low install friction with a pure Python wheel distribution.
- Active maintenance with a recent release (154 days ago) and ongoing repository activity; supports current Python versions (3.10–3.14).

What it is and what it does
CairoSVG is a Python library that renders SVG files to multiple output formats—PDF, EPS, PostScript, and PNG—by delegating rendering to the Cairo graphics engine. It wraps Cairo functionality through cairocffi and uses cssselect2 and tinycss2 to parse SVG stylesheets and selectors, defusedxml to safely parse XML, and Pillow for raster image handling. The library is stable (Production/Stable status), actively maintained, and supports modern Python versions from 3.10 onward.
Typical use cases include batch conversion of vector graphics for print or web distribution, programmatic SVG-to-PDF generation in document pipelines, and rendering SVG content to raster formats when vector output is not required. The copyleft LGPL license means you must disclose modifications if you redistribute the library, but using it as a dependency in your own application is straightforward.
Use it for
- Convert SVG graphics to PDF for embedding in reports or print-ready documents.
- Batch export SVG icons or illustrations to PNG for web use or mobile apps.
- Generate PostScript or EPS output from SVG for legacy printing systems or archival.
- Programmatically render SVG content in a document generation pipeline without manual design tool steps.
- Transform vector graphics to raster formats when downstream tools require PNG or similar formats.
