How to compress a video to 25 MB

What to expect
- Supported inputs
- Any media file this browser’s engine can read.
- What happens
- The default limit is 25 MB. Bitrate is estimated from the limit and source size, then the output is checked against the limit and original file size. A smaller input is never intentionally expanded to fill the limit.
- Limits
- A bitrate estimate is not a size guarantee. Very short size budgets, unsupported codecs, or device memory limits can prevent a valid export.

Questions
Many email and upload forms reject files over 25 MB. You can change the limit if you need a different cap.
About a minute at 1080p, or about two minutes at 720p. Longer videos are scaled down automatically; for the best picture, trim the clip first.
The export stops instead of handing you an oversized file. Trim the video, raise the limit, or try a different file.
