About the Video Converter
The Video Converter changes a clip into a wide range of formats — MP4, MKV, MOV, M4V, WebM, AVI, FLV, WMV, MPEG, MPG, TS and OGV. Pick the container the device or app you are targeting needs; MP4 (H.264) is the safe default that plays almost everywhere. All processing happens in your browser with ffmpeg (WebAssembly), so your video is never uploaded — it is private and free with no watermark. It works best on short clips, since the work runs on your device rather than a server.
Converting re-encodes the video, so it is best for short clips. If you just need a smaller file in the same format, the compress tool is faster; if you only need the sound, use Video to MP3.
Frequently asked questions
Is my video uploaded?
No. Conversion runs entirely in your browser.
MP4 or WebM — which should I pick?
MP4 (H.264) plays on almost any device and app, so it is the safe default. WebM is an open format that suits some websites.
Why is converting slow?
It re-encodes the whole clip on your device, so longer or higher-resolution videos take more time. Short clips are quick.
Does converting reduce quality?
Re-encoding can lose a little quality. The tool uses high-quality settings to keep the change small.
