Make your video smaller without sending it anywhere
Compression happens in your browser. Your file never leaves your computer, never touches a server, and there is no upload wait — which also means there is no file-size cap imposed by someone else’s bandwidth.
Why videos are too big
Phones record at very high bitrates, and a 4K clip can run hundreds of megabytes for a few seconds. Most places you want to send it are far smaller: Gmail stops at 25MB, Slack at 1GB on paid plans and much less on free ones, and most contact forms are stricter still.
Compressing re-encodes the video at a lower bitrate, and optionally scales it down. The picture changes a little; the file gets a lot smaller.
Which setting to choose
- Balanced — the default. Good quality at a much smaller size. Right for almost everything.
- High quality — barely visible change, more modest savings. Use when the video matters more than the megabytes.
- Smallest file — caps the video at 1280px wide and compresses hard. Use when something has a limit you must get under.
Already-compressed files
If your video is already an efficiently encoded MP4, compressing again may not help — and can even make it slightly larger. The tool tells you when that happens rather than handing back a bigger file and calling it a win.
