The file never leaves your machine.
253 file conversion tools that run entirely in your browser. Convert, compress and edit files with no account, no upload and no size limit.
How it works
Why there's no upload
Most online converters send your file to a server, do the work there, and send a result back. That round trip is where the wait comes from, the file size limits, and a copy of your file sitting on hardware you don't control.
Browsers can already decode images, parse documents and encode media on their own, so none of that detour is necessary. Every tool here just does the work on your device instead.
Your file stays on your device
Each tool reads your file into your browser's memory, processes it locally, and hands back a download. Nothing is uploaded, so there's nothing to protect with a privacy policy or a retention schedule: the file never leaves your machine in the first place.
Free, because it costs us nothing to run
Hosting 253 tools is cheap, and the conversions themselves cost us nothing, since your device does the work. Display ads cover the rest. No premium tier, no account, no data to sell.
The one real limit: a tool has to fit in a browser tab, so a file larger than your device's memory needs desktop software instead. The page will say so rather than fail halfway through.
Who runs this
Convert Filez is built and maintained by a small team who work on browser based tools. There is no support queue standing between you and us: write to info@convertfilez.org and a person on the team reads it.
Accuracy and corrections
Every tool page documents which formats it accepts, what it produces and where browser support is uneven. Where a browser cannot do something natively the page says so before you select a file, rather than failing halfway through. If a tool gives a result you believe is wrong, tell us and name the specification its page follows.
Where to start
The explore page lists every tool grouped by category. If you already know what you need, the search box in the header opens with command K and matches on tool name, file format or task.
