About LocoPDF
Private PDF tools for people who do not want their documents passing through someone else's servers.
Who built this
LocoPDF is built by a solo developer who believes your documents should stay private.
Why it exists
Most PDF tools require uploading files to remote servers. That means your contracts, tax forms, medical records, and business documents pass through someone else's infrastructure. LocoPDF takes a different approach — everything runs in your browser.
How it works
LocoPDF uses JavaScript and WebAssembly-powered PDF libraries to process files directly in your browser's memory. When you use a tool, the work happens on your device and the document does not need to leave it.
Mission
To provide professional PDF tools without compromising privacy.
Trade-offs
Client-side processing has limitations — very large files may be slower, and some advanced features require more browser resources. We think the privacy trade-off is worth it.
