MOV to MP4

Upload a .mov file (Apple's QuickTime format, the default recording format on iPhones, iPads, and Macs) and convert it to .mp4 — the most widely supported video format across all devices, browsers, and platforms. The tool re-encodes using H.264 video and AAC audio, which produces a clean, universally playable MP4.

This is especially useful when sharing videos from Apple devices with Windows or Android users, uploading to platforms that prefer MP4, or embedding video on a website where broad codec support matters.

Everything runs in your browser using ffmpeg.wasm — your video is never uploaded to a server. The first load takes a few seconds to download the WebAssembly runtime.

Frequently asked questions

Why not just rename .mov to .mp4?

MOV and MP4 are both container formats that can hold similar codecs, but they're not identical. A simple rename may work sometimes, but often produces playback issues because the internal metadata structure differs. This tool re-encodes the video properly so the result is a valid, universally compatible MP4.

Will the conversion lose quality?

There is a small quality loss from re-encoding, as is inherent in any transcode between lossy codecs. The tool uses CRF 23 (ffmpeg's default for H.264), which is a high-quality setting where the loss is imperceptible for most content. If your source MOV is already H.264, the result will be visually identical to most viewers.

Does this upload my video to a server?

No. The conversion runs entirely in your browser using ffmpeg.wasm. Your video stays on your device throughout the process.
