How to compress a video to 500 MB
Choose a long recording or a large phone or camera video and keep the 500 MB target, or enter another limit. The compressor picks a bitrate and resolution that fit, encodes the video in your browser, and measures the finished file before offering the download. Nothing is uploaded, so a multi-gigabyte file is fine.

What to expect
- Supported inputs
- Any media file this browser’s engine can read.
- What happens
- The default limit is 500 MB. Bitrate is estimated from the limit and the video's length, and the resolution steps down when the budget is too tight for a sharp picture. The output is checked against the limit. A smaller video is never made larger to fill it.
- Limits
- A long video takes a while to encode in a browser. Device memory and unsupported codecs can prevent an export; the page says so rather than handing over a broken file.
