Frequently asked questions
How does the video compressor work?
Pick a target size of 10, 25, 50, or 100 MB and the tool re-encodes the video in your browser until it fits under that cap. Nothing is uploaded.
Will compressing reduce the quality?
Some quality loss is unavoidable when you shrink a file, because the tool lowers the bitrate to hit your target. The smaller the target, the more visible the difference.
Is there a watermark or a sign-up?
No watermark, no sign-up, no ads. The tool is free and handles files up to 500 MB.
Does it work on a phone?
Yes, it runs in any modern browser. On iPhone, very large videos can run out of memory, so shorter clips work best there.
