About MP4 to MOV
MP4 pairs H.264 video with AAC audio in the ISO base media container for universal playback. MOV repackages the same streams in Apple's QuickTime container, which suits Apple editing workflows and camera-original archives. Where codecs match, stream copy moves streams without re-encoding; otherwise the picture re-encodes with small losses. Some codecs inside need transcoding before browser playback, so confirm the result plays in the target app. Keep the MP4 where universal sharing matters.
Why convert MP4 to MOV?
- Smaller files with MOV lossy compression.
- Keep animation and transparency where supported.
- Private, no upload - runs in your browser.

When not to convert MP4 to MOV
- Skip MOV for archival masters: lossy compression discards detail, so keep the MP4 original.
- Keep a master copy: repeated exports stack small losses, so archive MP4 before batch MOV shares.
Limits
Starting point: MP4 - H.264 video with AAC audio in one file. H.264 has no alpha channel, so transparency is dropped. Some codecs inside need transcoding before browser playback. Encode MOV (H.264 / AAC) from MP4 at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
