About this tool

MOV files mostly come from iPhones, iPads and Macs. The problem: a MOV doesn't always open on Windows, on Android or on some websites. MP4 plays on every phone, computer, social network and messaging app. Drop the video: when possible, the frames are simply copied into an MP4 with no quality loss. Everything happens in your browser.

When to use it

Share on social media or messaging apps

MP4 is the format Instagram, TikTok, YouTube, WhatsApp and most websites expect.

Play the video on any device

TVs, Android phones, iPhones and computers all play MP4.

Edit or archive

Editing apps import MP4 without extra plug-ins.

How to use

  1. Drop your MOV file.
  2. Untick “Keep sound” if you don't want it.
  3. Start the conversion to MP4.
  4. Download the MP4 or move on to compression.

How it works

MP4 is just a “container”: it can hold the same frames as the MOV. When the video codec is compatible (H.264, HEVC), the tool copies the frames without recompressing them, which takes seconds and loses nothing.

Otherwise (VP8, VP9 or AV1, common in WebM and MKV), the video is re-encoded with your device's codecs. Conversion runs in your browser with the Mediabunny library; your file is never uploaded.

Tips for best results

  • If the file is too large, compress the MP4 afterwards.
  • Keep the original until you've checked the MP4.
  • A recent computer converts much faster than an old phone.
  • For other output formats (WebM, MOV, MKV), use the general video converter.

Common problems and fixes

Conversion fails right away

Your browser may not support video processing: use a recent Chrome, Edge, Safari or Firefox.

Conversion takes a long time

The video must be re-encoded because its codec doesn't fit in an MP4 as is. Wait, or use a computer.

My AVI file is rejected

Browsers can't read AVI: convert it with installed software (VLC, HandBrake).

Frequently asked questions

Is quality preserved?

Yes when the frames are simply copied. When re-encoding, quality stays high but isn't bit-for-bit identical.

Is my video uploaded?

No, conversion happens entirely in your browser.

Is there a size limit?

No fixed limit: it depends on your device's memory. Several gigabytes work fine on a computer.

Is the sound kept?

Yes, unless you untick “Keep sound”.
