Trim a video online, free, private, no upload

Cut a video down to the part that matters without uploading it anywhere. Supercut decodes, trims and re-exports your clip entirely in your browser, so nothing is sent to a server. Tell it the range in plain English and get a clean, trimmed file back.

    The trim runs locally and you preview it instantly. Export the trimmed clip in seconds, it stayed on your device the whole time.

Tips

  • Lead with your hook in the first 3 seconds for social.
  • Cut dead air at the start and end before adding captions.
  • Trim first, then compress, so you are not shrinking footage you will drop.

Why it stays private

Supercut decodes, edits and exports your video entirely in your browser with WebAssembly. Your footage is never uploaded, the only thing that leaves your device is the text of your prompt, so the AI knows what edit to plan. Read more in our Privacy Policy.
