Is MOV to MP4 free? Is there a watermark?

Yes — MOV to MP4 is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. MOV to MP4 runs entirely in your browser with WebAssembly, so your MOV (QuickTime) file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

MOV to MP4 accepts MOV (QuickTime) and gives you back a MP4 file. Actual codec support depends on what the bundled engine or browser decoder can read.

Will I lose quality converting to MP4?

The H.264 conversion is lossy rather than a reversible container change. Keep the source and compare motion, fine text, colour, and audio sync in the result.

Best for: iPhone, camera, or QuickTime footage that needs a broadly accepted upload and playback format without depending on the original MOV container.
Input → output: A MOV source becomes a fast-start H.264/yuv420p MP4 with 128 kbps AAC audio. Both picture and sound are re-encoded into the delivery file.
Quality tip: Keep the MOV original until colour, orientation, frame cadence, and audio sync have been checked on the target platform.
Know before running: This is not metadata-only wrapping. Re-encoding can change quality, and alternate audio, timecode, alpha, professional camera metadata, or other secondary MOV streams are not explicitly retained.
Next step: Compress video if the compatible MP4 is still too large to send or upload.
