How to Compress a Video Online
Drop your video and pick a preset: smaller file for sharing, balanced for most uses, or best quality for archiving. Compression runs on your device — typical videos shrink 60–80% with little visible difference.
Tip: compressing twice doesn't shrink much more and adds artifacts. Use the strongest preset from the start.
