Compress a video
Phones record in very high quality, so a short clip can weigh hundreds of megabytes — too heavy for email, messaging or upload limits. Compressing re-encodes the video at a smaller bitrate so it fits and sends easily.
You choose the balance: a little compression keeps near-original quality, more compression makes a tiny file for quick sharing.
It all runs in your browser with WebAssembly — your video is never uploaded to a server.
Frequently asked questions
Is it free?
Yes, free and no sign-up. The video engine loads once (~30 MB), then everything is local.
Is my video uploaded?
No, never. The compression is 100% local.
How small can it get?
It depends on the source and the quality you choose — you can often cut the size by half or more.
