Repackage video file bytes into MP4, AVI, MOV, MKV, or WebM container types in your browser (up to 50 MB). This is local remux/labeling — not a full codec re-encode.
No. The tool rebuilds a Blob with the selected container MIME type from the original file bytes (local remux/re-label). Codec re-encoding is not performed, so playback depends on the original streams remaining compatible with the new extension/player.
Mute/strip attempts a native edit for MP4/MOV/M4V/3GP-style files. Other containers may keep their original audio tracks.
Processing stays on your device. Prefer smaller clips on phones because holding a full video in memory is demanding.
