MOV to MP4, in your browser
MOV is the video format iPhones and Macs record in. It’s fine in the Apple world, but drop a MOV onto Windows, Android, or many websites and you’ll hit playback problems. Converting to MP4 (H.264) — the most universally supported video format — makes it play anywhere.
Mynify converts entirely in your browser, so your video is never uploaded to a server. Most “MOV to MP4” sites send your whole file to their servers first; Mynify keeps it on your device.
What to expect
Converting to MP4 re-encodes the video with H.264 and AAC audio for maximum compatibility. That means:
- The first run loads the engine (~30MB, cached afterwards).
- Longer clips take longer, because it’s your device encoding, not a server.
- The result is a clean MP4 that plays on phones, computers, browsers and TVs.
Tips
- Trim first if you only need part of it — use the video trimmer to keep the encode short.
- Just want the sound? MP4 to MP3 works on MOV files too.
