Is converting MOV to MP4 free?

Yes. The converter is free with no watermark, no sign-up and no file limit beyond your device's memory.

Does my video get uploaded?

No. The conversion runs entirely in your browser, so the video never leaves your device — there's nothing to upload or wait for.

Will the MP4 look worse than the MOV?

No. The video stream is typically repackaged rather than re-encoded, so the picture quality is unchanged.

Can I convert large videos?

Yes — files up to about 1 GB work well. Very long videos simply take a little longer to process.

How to Convert MOV to MP4 (Free, No Upload)

How to convert MOV to MP4

MOV is the format iPhones, iPads and Macs use for screen recordings and camera footage. It plays perfectly inside the Apple ecosystem — and then refuses to open on a Windows laptop, an Android phone or the TV you want to show it on.

The fix is converting to MP4, the one video format practically every device, browser and editing app understands. This guide shows how to do it for free in your browser, without installing a converter or uploading your video anywhere.

Convert MOV to MP4 in your browser

The conversion runs on your own device using WebAssembly, so even long personal videos never leave your computer.

1Open the free MOV to MP4 tool.
2Drag your .mov file into the box, or click to browse for it.
3Click Convert to MP4 and wait a few seconds while it processes.
4Download the MP4 and play or share it anywhere.

Why the quality doesn't drop

MOV and MP4 are containers — boxes that hold the actual video and audio streams. In most cases the video inside a MOV is already encoded with H.264, which MP4 supports natively, so converting mostly repackages the same streams into a new box rather than re-compressing the picture.

That's why the converted file looks identical to the original and finishes quickly: nothing about the image itself is being degraded.

When to convert (and when not to)

Convert when you need to send a clip to a Windows or Android user, upload it to a site that rejects MOV, or archive footage in the most future-proof format.

If the video only ever lives on your Apple devices, you can leave it as MOV — the formats store the same content, so there's no quality reason to convert until compatibility forces it.
