Overview

Developers building document viewers, converters or PDF tooling often need a rendering engine that is fast, small and reliable across formats. MuPDF is a lightweight open-source software framework for viewing and converting PDF, XPS and e-book documents, so applications can render pages and extract content without relying on heavy desktop software. As a library, MuPDF can be embedded into your own applications, command-line tools or services. Its documentation covers the core APIs and build instructions, which makes it practical to integrate into existing pipelines for document processing. MuPDF is licensed under the GNU Affero General Public License v3, so it is free to use, modify and redistribute under its terms. Commercial licensing is available directly from Artifex Software for projects that cannot meet AGPL obligations. The project is developed by Artifex Software and is discussed on its public Discord server, with bugs reported through the Ghostscript bugzilla.
