About Filezuma

Merging a contract, signing a form or shrinking a scan for email are small jobs, but the files involved are often private: payslips, medical letters, leases, IDs. Most online PDF tools handle them by uploading them to a server first.

Filezuma does it the other way round. Modern browsers can run the same kind of document software a desktop app would, so 41 of our 47 tools do all their work on your own device. The file never leaves it.

A few conversions — like Word to PDF — need software that cannot run in a browser. For those we use our own server, say so on the page before you start, and delete the file as soon as it is done. The privacy page has the details.

Free, without the catch

You never need an account or an email address to use the tools. Because most of the work happens on your device rather than ours, they cost us very little to run — which is why they are free. People who convert Office documents often can choose Pro, which removes the daily limit on our server conversions.

Built on open source

Filezuma stands on well-tested open-source projects, including pdf-lib, Mozilla's pdf.js and qpdf. The full list is on our licences page.
