Frequently asked questions
Which video formats can I compress?
MP4, MOV, MKV, WebM, AVI, M4V, WMV, FLV, MPEG, 3GP and MPEG-TS (TS, MTS, M2TS). The result is always an MP4.
How much smaller will my video be?
It depends on the source. A 4K phone video usually shrinks a lot at the Recommended or Strong level. A video that was already compressed for the web changes less. The page shows the size before and after.
Is the sound kept?
Yes, the audio track is kept and encoded in AAC at 128 kbps.
What is the maximum size?
500 MB per video on the free plan, and more on paid plans. Video compression counts as one file in your free daily allowance.
Can I only change the format, without compressing?
Yes, use a converter such as MOV to MP4 or MKV to MP4 instead. Links are below.

Why phone videos are so heavy
Phones record at a very high bitrate, often in 4K, to keep every detail. For sharing, a lower bitrate and a 1080p or 720p resolution look almost the same on a screen and take a fraction of the space.
What each level does
Light keeps the original resolution with a high quality setting. Recommended limits the video to 1080p with a more efficient setting. Strong limits it to 720p. Smaller videos are never enlarged. Sound is kept as AAC at 128 kbps.
An MP4 that plays everywhere
Whatever you upload (MOV from an iPhone, MKV, AVI, WMV), you get an MP4 in H.264 and AAC, prepared for streaming so it starts playing before it is fully downloaded.
