MOV to MP4 Converter

Why convert MOV to MP4?

MOV is Apple's QuickTime container — the default for iPhone and Mac recordings. It works beautifully inside Apple's ecosystem, but step outside and friction appears: many Windows media players stumble on it, some Android phones refuse it, older smart TVs won't list it, and certain video editors and web uploaders accept only MP4. MP4 with H.264 is the one format that plays everywhere, no questions asked.

The good news: most MOV files from iPhones already contain H.264 video, so converting to MP4 is mostly a re-packaging job — fast, and with no meaningful quality loss. Even when re-encoding is needed, a high-quality pass preserves essentially all visible detail.

How to convert MOV to MP4 (3 steps)

1. Select your MOV file. Click the box or drag it in. It is read directly by your browser — nothing uploads.
2. Convert. One click. The video becomes MP4 (H.264 + AAC), the most compatible format in existence.
3. Download. Save your MP4. It plays on Windows, Android, browsers, TVs — and uploads to every platform.

Private by design: nothing is uploaded

This tool runs FFmpeg, the industry-standard video engine, compiled to WebAssembly and executed entirely inside your browser tab. Your video never travels over the network — check your browser's network tab if you like. It is safe for private clips and works on slow connections, because only the ~30MB engine downloads once.

MOV vs MP4: what is the difference?

Both are containers, and both usually hold the same H.264 video and AAC audio inside. MOV is Apple's container, MP4 is the ISO standard container — technically cousins, with MP4 enjoying near-universal support. For iPhone-to-iPhone sharing, keep MOV. For anything cross-platform — sending to a Windows user, uploading to a website, playing on a TV — MP4 is the safe choice. File sizes are nearly identical; compatibility is the whole story.

One note: if your MOV already plays everywhere you need it, don't convert — every re-encode loses a tiny amount of quality. Convert when compatibility demands it.
