Supported formats
Real format support only
This page is generated from the live FormatOS format registry. Every format listed here is processed directly in your browser — your files stay on your device, and on this site nothing is uploaded to a server. No format is listed unless a working tool exists for it.
Many file conversion sites list dozens or hundreds of formats to appear comprehensive, regardless of whether the tool behind each one actually works. FormatOS takes the opposite approach: only formats with a functioning action appear here. If a format is missing, it is not yet supported.
Browser-processed formats
17
Files stay on your device. Processing runs inside your browser tab using JavaScript-based conversion engines (pdf-lib, pdf.js, canvas, JSZip, and others).
No permanent storage
0
Files you upload are not stored in a user library, shared with other users, or retained beyond the conversion session. There are no public galleries or file hosting features.

What "Processing" means
Understanding the registry columns
The table above uses three status columns. Import means FormatOS can accept files in this format as input. Export means FormatOS can produce output in this format — "Limited" means conversion to this format is available but output quality may vary depending on the source content. Processing tells you where the work happens: browser-capable means the conversion runs on your device without any file leaving your computer.
This deployment runs entirely in your browser — there is no server, so every format above is processed on your own device with no upload. Formats that would need a server engine (such as video and audio conversions) are not listed here because they cannot run in a browser-only build.
Need to process a file? Use the homepage upload workspace. FormatOS detects the file type and shows only the actions that apply to it. For more on how this works, see How File Processing Works.
