MOV compression usually creates MP4
MOV is common for phone and camera footage. For sharing, a compressed MP4 is usually smaller and easier to play.
Best settings and limits
Best first try
Use 720p for a normal shareable video. Use 480p for stronger size reduction.
When this may fail
Large 4K MOV files can be too heavy for browser memory. Desktop Chrome is the safest first try.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
