Same quality bar. Still free. Still no upload.
Your files never leave your device
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop a photo or video
PNG, JPEG, WebP, MP4 or WebM. The file is read in this tab only.
2. Detect or draw boxes
Auto faces via MediaPipe or the browser FaceDetector API. Draw amber boxes for plates, screens or anything detection misses.
3. Export blurred media
Download a PNG or JPEG still, or a canvas-re-encoded WebM/MP4 when your browser supports captureStream.
Questions
Does auto face detection upload my photo?
No. Detection runs in your browser. MediaPipe may download a small WASM and BlazeFace model from a CDN on first use; your image or video is never sent with that request. If MediaPipe cannot load, the tool falls back to the browser FaceDetector API or manual boxes only.
Can I blur license plates and screens?
Yes. Turn on Draw blur box and drag rectangles over plates, UI, badges or anything else. Manual boxes are fixed for the whole video export. Auto face boxes can refresh while recording when MediaPipe VIDEO mode is available.
Will video export work in Safari?
Often not. Safari frequently lacks canvas.captureStream or a usable MediaRecorder path. Use Download current frame PNG there, or open Chrome, Edge or Firefox for a full blurred clip. Same limit as the free video trimmer and social compress tools.
Is the blur reversible?
Strong pixelate or blackout permanently destroys detail in those pixels for practical recovery. Light Gaussian can leave structure if strength is low. Prefer pixelate or blackout for sensitive faces and plates, and double-check coverage before you share.
Do my files get uploaded anywhere?
No. This free tool runs entirely in your browser using the Canvas and File APIs. The file you choose is read into memory on your own machine, processed there, and offered back as a download. Nothing is sent to a server, which is also why it keeps working with your network off.
Is it actually free, or is there a catch?
Actually free, with no account and no limit, because it costs nothing to run. The work happens on your device rather than on our hardware. That is different from generating with an AI model on Versely, which does cost credits. There is no free tier for generation.

These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
