Video Converter — Free, No Signup

Convert video to MP4, WebM, MKV, MOV, AVI, MPEG, FLV, WMV, 3GP or animated GIF — or extract the audio track. FFmpeg in WebAssembly, 100% local. No signup required.

How it works

1. Upload a video file: MP4, MOV, AVI, WEBM and more — nothing is uploaded to a server.
2. Pick a target format: MP4, WebM, MKV, MOV, AVI, MPEG, FLV, WMV, 3GP, or extract as an animated GIF or audio-only file.
3. Download the converted file: FFmpeg runs in WebAssembly, 100% on-device.

Frequently asked questions

How is this different from CloudConvert or similar?
The same FFmpeg engine those services rely on runs directly in your browser via WebAssembly here — your video is never uploaded, and there’s no per-file limit tied to a paid plan.

Can I extract just the audio from a video?
Yes — audio-track extraction is one of the supported outputs.

Will large video files be slow to convert?
Conversion speed depends on your own device’s CPU, since there’s no server doing the work — larger files and higher resolutions take longer.
