About
Built for privacy. Built for speed.
PDFMuse is a free, browser-based PDF toolkit. Every tool runs entirely on your device — your files never leave your browser, never touch a server, and are never stored anywhere.
Our mission
Most online PDF tools work by uploading your files to a remote server, processing them there, and returning the result. That means your contracts, invoices, medical records, and personal documents pass through systems you cannot inspect or control.
PDFMuse takes the opposite approach. We use modern browser APIs — specifically WebAssembly-compatible PDF libraries — to run every operation locally. The result is a tool that is both more private and faster, because there is no round-trip to a server.
Our goal is to build the most useful, most private PDF toolkit on the web. We believe privacy should be the default, not a premium feature.
How we build
- Browser-first processing
- Every PDF operation — merging, splitting, compressing, rotating — runs in your browser using JavaScript and WebAssembly. No server is involved.
- No file storage
- We have no infrastructure to store files. Even if we wanted to, we could not — your files never travel over the network.
- No account required
- Every tool is available immediately. No sign-up, no email, no subscription tier. Just open the tool and use it.
- Static architecture
- The site is a fully static Astro build served from Cloudflare Pages. There is no application server, no database, and no backend logic.
Available tools
- Merge PDF — Combine multiple PDF files into a single document.
- Split PDF — Separate a PDF into multiple files or extract pages.
