Convert AVI, WMV, MOV, FLV to MP4

Convert AVI, WMV, MOV/ProRes, FLV or MPEG video to MP4 in your browser — no upload, no signup. Old and pro formats to standard MP4, free.

Turn older or professional video formats into a standard MP4 without uploading them. Convert AVI to MP4, WMV to MP4, MOV or ProRes to MP4, FLV to MP4, or MPEG to MP4 — all in your browser. A slimmed-down build of FFmpeg runs inside the page to decode formats the browser can’t read on its own, then encodes a standard H.264 MP4 that plays anywhere. Useful for opening old clips on a modern device, sharing a ProRes file as a playable MP4, or rescuing footage from an outdated format. The file never leaves your device. Free, no account, no watermark.

How it works

1. Open an AVI, WMV, MOV, FLV or MPEG file
2. The in-browser FFmpeg engine decodes it
3. It is re-encoded to a standard MP4 — no upload
4. Download the converted MP4
