Compression runs in your browser. The video never leaves your device unless you choose to share it.

Why? Compression is solved. FFmpeg has been doing this for 25 years. There's no reason to upload your private clips to some server, wait in a queue, and download a watermarked result.

What you can do

  • Compress videos right in your browser — High / Medium / Low / target-size presets.
  • Paste a link from TikTok, YouTube, Instagram, X — we fetch the file for you.
  • Extract audio from any clip as MP3.
  • Trim & split a video down to just the part you want.
  • Share for 24 hours with an auto-previewing link that embeds in iMessage, Discord, and Slack with a thumbnail and inline player.

How it works

FFmpeg.wasm runs entirely in your browser. The ~30 MB engine downloads once and gets cached. After that, compression works offline.

The link-download & share features run on a small server because browsers can't fetch files from third-party sites. Files dropped into the share bucket auto-delete after 24 hours — no permanent storage, no accounts.

No login. No "premium tier." No "3 free conversions." Just pick a video and go.
