Convert MOV to MP4 online for free. 100% secure, fast, and private local file conversion directly in your browser. No software installation required.
Why convert MOV to MP4?
MOV files are everywhere because they are the default recording format for iPhones and most mirrorless and DSLR cameras — but they are also the format most likely to refuse to play. Windows PCs, Android phones, smart TVs, and browser-based editors routinely struggle with QuickTime's MOV container, and cloud storage previews often come back blank. If you record on Apple gear and need to send footage to a colleague, upload it to a course, or edit it outside Apple's software, converting MOV to MP4 is the standard fix.
WasmConvert handles this conversion entirely in your browser, so your clips never leave your device — relevant for family footage and unreleased work. The tool re-encodes the video stream to H.264 and the audio to AAC inside an MP4 container, and you can adjust the quality level before exporting. There is no upload, no queue, and no file-size cap, so even multi-gigabyte 4K MOV files from a camera card convert locally at a speed limited only by your hardware.
Common use cases
- iPhone and camera footage that must play on Windows PCs, Android phones, and smart TVs
- Sending MOV recordings through email, WhatsApp, or a work chat that blocks QuickTime files
- Preparing Apple-shot video for browser-based editors and web platforms that only accept MP4

Pro tips for MOV to MP4 conversion
- Check whether your iPhone or camera recorded HEVC (H.265) inside the MOV; re-encoding to H.264 MP4 guarantees playback on older devices and platforms without HEVC decoders, at the cost of a larger file.
- If the MOV carries a second audio track or timecode metadata, expect the MP4 to keep only the primary audio — verify the sound after conversion rather than assuming every track survived.
- For 4K MOV footage, pick a mid-range quality setting instead of the maximum: H.264 at moderate quality is visually indistinguishable on most screens and keeps the MP4 a fraction of the source size.
