Fast when possible
If your video already uses H.264 (most iPhone MOV and MKV files do), the video is moved into an MP4 file without re-encoding. That takes seconds and keeps the exact original quality.
Supported formats
MOV, WebM, MKV, MPEG-TS (.ts) and MP4. AVI, WMV and FLV are not supported yet.
Private by design
Your video is converted on your own device and never uploaded.
Frequently asked questions

- Can I convert AVI files?
- Not yet. AVI, WMV and FLV support is coming.
- Is my video uploaded?
- No. Conversion runs in your browser.
