File Converters

Pick a format to convert from and a format to convert to. Every conversion has its own page and runs in your browser, so your files are never uploaded.

How these converters work

Image conversions use your browser's built-in image engine. Video, audio and GIF conversions run FFmpeg compiled to WebAssembly inside the page; the engine (about 30 MB) downloads the first time you use one and is then cached. Document conversions extract text and rebuild it in the new format. Nothing you convert is uploaded.

What is not supported

Camera RAW, PSD, CAD, fonts, scanned-PDF text recognition in document conversions, DRM-protected ebooks, MOBI/AZW3, and legacy DOC/PPT/XLS need server-side software and are not offered. Text-based conversions say so on each page, and the format picker only offers conversions that actually work.
