Why convert MP4 to MOV here?

- Preserves timecode and metadata that sometimes gets stripped in MP4 round-trips.
- Runs locally — no upload of client footage to a third-party service.
FAQ
Is this MP4 to MOV converter really free and without upload?
Yes. The tool runs entirely in your browser using FFmpeg compiled to WebAssembly. Your MP4 file never leaves your device — open the DevTools Network tab to verify zero uploads. No signup, no watermark, no size cap beyond browser memory (~2 GB).
Will converting MP4 to MOV reduce quality?
The converter re-encodes to MOV with CRF 23 (visually lossless for most footage). If you need stream-copy instead (no re-encoding), use the Converter tool directly and toggle the codec-copy option.
How long does MP4 to MOV conversion take?
On an M2 MacBook, a 1-minute 1080p clip converts in about 8 seconds. 4K clips scale roughly linearly. Old machines are slower — processing uses your CPU and GPU, not our servers.
Can I batch-convert multiple MP4 files?
Not yet — the current flow converts one file at a time. Queue multiple tabs if you need parallel conversion.
