Overview
MuPDF is a C library for working with PDF and other document formats, with bindings for Python (PyMuPDF), Node.js and JavaScript (MuPDF.js) and C# (MuPDF.NET). It handles extraction, rendering, redaction, annotation, digital signing, merging, splitting, compression and format conversion. A WebViewer product built on the same engine embeds a document viewer into a web page or app.
- Best for
- Developers embedding PDF viewing, editing and extraction into their own applications
- Pricing
- No prices are shown; the site only offers a Contact Sales route for a commercial licence.
Strengths and trade-offs
Strengths
- Bindings for C, Python, JavaScript/TypeScript and C#
- Covers extraction, rendering, redaction, signing and merging
- Reads PDF, ePUB, XPS, CBZ, SVG and common image formats
- Commercial licence permits redistribution without source disclosure
Trade-offs
- No prices published; licensing runs through a sales contact
- Technical support is tied to buying a commercial licence
- ePUB, XPS and CBZ are input-only; they are not output formats
- An embeddable SDK, so integration work is required

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Customer sentiment
Third-party ratings, shrunk toward the catalogue mean by review volume and corroborated across independent sources.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
