Drop files below. Nothing is sent to a server - the conversion runs on your own machine.

The container changes; the video itself is copied across untouched. Re-encoding, trimming and joining need the app.

Your files never leave this computer. There is no upload and no server doing the work. The conversion code runs inside this page, That is also why video here is limited to changing the container: copying streams into a new box is quick, but re-encoding one in a tab is not something a browser does well.

What converts where

The honest division of labour. A browser is very good at some of this and hopeless at the rest.

In this browser

Images

JPEG, PNG, WebP, GIF, BMP and AVIF in. JPEG, PNG or WebP out. Instant, at any size, using the browser's own image engine.

In this browser

Audio

MP3, WAV, FLAC, M4A, OGG, Opus and more. The engine is a WebAssembly build of FFmpeg, about 31 MB, downloaded once when you first convert audio.

Windows app

Video

MP4, MKV, MOV, AVI, WebM and the rest, with hardware encoding, resolution changes, trimming, cropping and subtitles. Files of any size.

Windows app

Documents

Word, Excel, PowerPoint, OpenDocument and PDF, converted by a bundled copy of LibreOffice. There is no browser equivalent worth trusting.
