Convert a video to MP4

How it works

1. Drop the video onto the box. MOV, M4V and MP4.
2. Choose whether to keep the sound.
3. Press Convert to MP4. It finishes in seconds, because nothing is re-encoded.

Frequently asked questions

Why is this so much faster than other converters?

Because most of them re-encode when they do not have to. A QuickTime .mov from an iPhone already holds H.264 or HEVC video and AAC audio — the same things an MP4 holds. All that differs is the container around them. This copies the tracks into an MP4 box as they are, so it takes about as long as reading the file and costs no quality at all.

Will it convert anything to MP4?

No, and a converter that claims it will is usually re-encoding behind your back. This takes MOV, M4V and MP4 whose picture is H.264 or HEVC (H.265, what an iPhone records by default). Something in another codec — ProRes, for instance — cannot be copied across as it stands, and you will be told so rather than handed a slow re-encode you did not ask for. Compress video re-encodes on purpose.

My MP4 will not play on an older device.

Rewrapping will not fix that: if the picture is in a codec the device cannot decode, the box around it makes no difference. Compress video re-encodes to a widely playable H.264 and is the tool for that.

Does the file get smaller?

Barely — the tracks are the same size, so only the container overhead changes. What does change is that the index is written at the front, so the file starts playing before it has finished downloading. If you need it smaller, that is Compress video.

Is my video uploaded?

No. It is read and rewritten in your browser, which is why a 150 MB file is fine here on the free plan when 20 MB is the limit elsewhere.
