Video Compressor

Compress Video Online — Free

Shrink a video's file size while keeping it watchable — pick a quality level, and a smaller file downloads automatically, no software to install.

How to Compress a Video

Upload your video and choose "Smaller file," "Balanced," or "Higher quality" depending on how much you're willing to trade size for sharpness. Click "Compress Video" and, once it's done, the compressed file downloads automatically — with a quick comparison of the original size against the new one.

How This Tool Works

This runs a real video encoder — the same kind of software used by professional video tools — compiled to run directly in your browser. It re-encodes the video at a different quality setting, which is where the size reduction comes from: lower settings allow more compression at the cost of some visual detail, higher settings keep more detail at a larger size. Because all of this happens on your own device rather than a server, it's slower than a typical online compressor — expect processing to take roughly as long as the video itself, and plan on more for longer or higher resolution files.

Good Uses for This Tool

Getting a video under an upload or email attachment size limit, shrinking a phone recording before sharing it, saving storage space on a large video library, or reducing file size before uploading somewhere with a slow connection.

Is It Actually Private?

Yes. The entire compression process runs locally in your browser using WebAssembly — your video is never uploaded to a server.
