or click to select it
Convert a MOV video (the typical iPhone format) to MP4, compatible with almost any device, player and social platform, without installing anything or uploading the file to a server.
Re-encodes both the video and audio of a MOV file into the MP4 container using H.264 (video) and AAC (audio), the most widely compatible combination available today.
Use cases
- Convert iPhone-recorded videos before uploading them to a site that doesn't accept MOV.
- Share a video with someone whose device can't play MOV.
- Prepare a video for editing in software that only accepts MP4.
How it works
- 1

Once it's done, download the converted video.
Technical details
Uses ffmpeg.wasm inside a Web Worker in your browser. Unlike a simple container swap, this re-encodes the entire video, so it can take several minutes depending on the file size and your device's power — a heavier process than, say, extracting just the audio.
Frequently asked questions
Why does this take longer than other conversions?
Re-encoding video (not just extracting audio) requires re-processing every frame, which is far more CPU-intensive, especially running single-threaded in the browser.
Does the video keep its quality?
It uses a balanced quality setting, very close to the original to the eye; re-encoding always involves some minimal lossy compression.
