Good to know
Your device does the compressing, one processor core at a time, because that is what a static website like this can do in a browser. It is slower than a desktop program: as a guide, on a laptop one minute of 1080p video takes from about a minute to a few minutes to compress to 720p, depending on how much is happening in the picture.
A sensible limit is files up to about 1 GB on a computer and a few hundred MB on a phone. The result is written to memory before you download it, so very large videos can run out.
The result is an MP4 with H.264 video and AAC sound, which plays almost everywhere. If your video is already well compressed, the tool tells you instead of giving you a bigger file.
Questions
Is my video uploaded?
No. The video stays on your device. The engine that compresses it runs in your browser.
Why is it slower than some other sites?
Other sites send your video to their computers. Here, your device does the work, using one processor core in the browser. It takes longer but the video never leaves you.
What's the best setting?
Balanced at 720p suits most clips: it usually makes a phone video several times smaller and still looks good on any screen.
Can I stop it?
Yes. Press Cancel at any time. Nothing is saved until the job is finished.
