MOV to MP4 Converter – Free & No Upload
Convert QuickTime MOV files to MP4 locally in your browser — your video never leaves your device
MOV is Apple's QuickTime container, and while it plays fine on Mac and iPhone, many Windows apps, websites and messengers expect MP4. This tool rewraps or converts your MOV into a standard MP4 right in the browser.
Most MOV footage from iPhones, GoPros and cameras already contains H.264 video. In that case the converter simply moves the streams into an MP4 container without re-encoding: zero quality loss, and even multi-gigabyte files finish in seconds.
How to convert MOV to MP4
- Choose or drag in your MOV file — nothing is uploaded, it stays on your device.
- Click Start. H.264 sources are rewrapped losslessly in seconds; other codecs are re-encoded to H.264 in your browser.
- Download your MP4.
Frequently asked questions
Is the conversion lossless?
When your MOV contains H.264 video (most iPhone, GoPro and camera footage), the streams are rewrapped into MP4 without being re-encoded — identical quality, done in seconds. Other codecs such as HEVC or ProRes are re-encoded to H.264 so the result plays everywhere.
Is my video uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your file never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing.
What is the maximum file size?
Up to 8GB on desktop browsers and 2GB on mobile. There is no limit on the number of files you convert, and no signup or watermark.
Why convert MOV to MP4?
MP4 with H.264 is the most widely supported video format: it plays on Windows, Android, smart TVs, and uploads cleanly to messengers, e-mail and web forms that reject or mangle MOV files.
