Blurring faces is the simplest way to share footage without exposing the people in it. The catch with most online tools is that you upload your private clip to a stranger's server first, which defeats the purpose. Supercut detects and blurs faces on your device in the browser, so the footage you are trying to protect never leaves your machine.
You might blur faces to publish street footage, post a clip filmed in public, share a classroom or workplace recording, or hand a video to a wider audience without identifying bystanders. In each case the people in frame did not agree to be recognizable, so removing their identity before you share is the responsible move. Here is the part most tools get wrong. To blur a face, software has to find the face first, and many web editors do that by uploading your video to their servers. The exact footage you are trying to keep private ends up copied onto someone else's computer. Supercut runs face detection in your browser, on your own device, so the sensitive clip stays with you the whole time. Your footage is never uploaded. Only your text prompt is sent, so the AI knows what edit to plan.
You do not scrub a timeline or draw boxes by hand. You drop your clip into the browser and type what you want in plain English, like "blur the faces in this video." Supercut runs an on-device face detector over the clip, works out the region where faces appear, and then blurs that area using FFmpeg compiled to WebAssembly. If it cannot find a face, it falls back to a full-frame privacy blur so the people in the clip are still covered. Because everything runs in the browser, the work happens on your own processor. There is no upload queue and no account needed to try your first export. Once the page has loaded you can keep editing even if your connection drops. When the preview looks right, you export, and the blurred clip is the only file that gets saved out.
Face blur works best on clear, well-lit, front-facing footage. Profiles, fast motion, heavy shadow, masks, and very small faces far in the background are harder to detect. If faces are scattered to opposite sides of the frame, or someone walks in and out, a single subject framed near the center is the most reliable case, so always watch the full preview before you export rather than spot-checking one frame. If a face is missed, you have options in the same session: increase the blur strength in your prompt, or fall back to a full-frame blur for guaranteed coverage. To remove identifying audio such as a spoken name, trim that section or replace the audio track. And if the clip is headed to a specific platform, blur first and then export with a TikTok, Reels, or Shorts preset so it is ready to post in one pass.
Go to supercut.cc and drag your video into the browser. It loads straight into the editor and stays on your device. There is no upload, and no account is needed to try your first export.
In the command box, type something like "blur the faces in this video." The AI reads only your text, not your footage, and plans the edit. Supercut then runs face detection on-device and applies the blur.
Supercut runs an on-device detector over the clip to locate where faces appear, then blurs that region. If no face is found, it applies a full-frame privacy blur instead so no one is left uncovered.
Play the blurred clip in the preview panel and watch it all the way through. Check tricky moments like profiles, fast movement, and people entering or leaving the frame to confirm every face you care about is covered.
When it looks right, export. The blurred video is rendered on your device and saved locally. Your original footage never left your machine, and the file you share is the protected one.

No. Face detection and blurring run on your device in the browser. That is the whole point: the sensitive footage you are trying to protect is never uploaded. Only your text prompt is sent so the AI knows what edit to plan.
It works best on clear, well-lit, front-facing footage and a single subject near the center of the frame. Profiles, heavy shadow, fast motion, masks, very small distant faces, and people spread to opposite sides of the frame are harder to cover, so always review the full preview before exporting.
Supercut falls back to a full-frame privacy blur, so everyone in the clip is still obscured rather than left exposed. You can also ask for a full-frame blur directly when you want guaranteed coverage.
You can try your first export free with no account. Unlimited watermark-free exports and every tool are part of a paid plan, which starts at 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 one time for lifetime access. You can cancel anytime.
Blurring faces removes the most obvious identifier, but it is not a guarantee of full anonymity. Voices, names spoken aloud, tattoos, clothing, badges, and license plates can still identify people, so review the whole clip and remove or obscure those details too.
