Make iPhone, QuickTime and Mac screen-recording MOV files play on Windows, Android and web forms by converting them to MP4. It runs in your browser; nothing is uploaded.
Your media is processed in your browser and is not uploaded to our servers for conversion. Page assets (including the converter engine) still load over the network.

Start with Fast mode
Fast rewraps the video as MP4 in seconds without losing quality.
Check it plays
Play the MP4 in the page. If it won't play where you need it, the video is probably HEVC.
Use Maximum compatibility if needed
Re-encodes HEVC video to H.264, which plays on every Windows PC and Android phone.
There are two separate problems. Some apps and upload forms simply don't accept the .mov extension; Fast mode fixes that by rewrapping the same video as .mp4 in seconds with no quality loss.
The bigger problem is the codec. With the default High Efficiency camera setting, iPhones record video in HEVC (H.265). Windows needs a paid extension from the Microsoft Store to play HEVC, and many Android phones, older TVs and websites can't play it at all. Changing the file to MP4 doesn't change the codec, so for these videos choose Maximum compatibility, which re-encodes to H.264. To avoid this in future, set Settings > Camera > Formats to Most Compatible on the iPhone.
MOV and MP4 are closely related containers, so Fast mode can move the H.264 or HEVC video and AAC audio straight into an MP4 without re-encoding.
Maximum compatibility decodes the video and re-encodes it as H.264 with AAC audio at a quality setting that is visually close to the original. Re-encoding happens frame by frame in your browser, so it is limited to 120 MB and 10 minutes on a computer.
Fast mode handles large iPhone recordings up to 500 MB on a computer without re-encoding.
Maximum compatibility converts HEVC to H.264 so the video plays on any Windows PC.
Portrait iPhone videos stay portrait in the MP4.
Family and work videos are converted on your device, never uploaded.
No. The conversion runs in your browser with a WebAssembly build of FFmpeg. The video is read from your device and the MP4 is saved back to it.
Most likely the video is HEVC (H.265), the iPhone's default with the High Efficiency camera setting. Windows needs a paid extension to play HEVC. Convert with Maximum compatibility to get H.264, which plays everywhere.
Fast copies the existing video and audio into an MP4 without re-encoding, so it takes seconds, keeps the exact quality and handles files up to 500 MB on a computer. Maximum compatibility re-encodes to H.264 and AAC, which play everywhere, but it is slower and works for videos up to 120 MB and 10 minutes on a computer.
Go to Settings > Camera > Formats and choose Most Compatible. New videos will be recorded in H.264. Existing videos stay HEVC.
Fast mode handles up to 500 MB on a computer and 250 MB on a phone. Maximum compatibility re-encodes every frame in the browser, so it is limited to 120 MB and 10 minutes on a computer, or 60 MB and 5 minutes on a phone. Trim longer videos first.
