About MOV to MP4 conversion
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.
Frequently asked questions
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.
Yes. HEVC footage is decoded and re-encoded to H.264 right in your browser so the MP4 plays on any device. Tip: recording in “Most Compatible” mode (Settings → Camera → Formats) produces H.264 MOV files that convert losslessly in seconds.
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.
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.
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.
Yes — completely free and unlimited, with no watermark, no signup and no daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
If the source already contains H.264 video, the file is rewrapped without re-encoding and finishes in seconds, even for gigabyte files. Other codecs are re-encoded in parallel WebAssembly workers, which runs at roughly real-time speed on a modern computer.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
AAC and MP3 audio is copied over unchanged. Other audio codecs (PCM from cameras, Vorbis, Opus…) are converted to AAC so the resulting MP4 plays everywhere.
