What does a face anonymizer actually do?

It finds the faces in an image and destroys the identifying pixels — here by blurring, pixelating, or covering each detected face. Blurify also strips the photo's EXIF metadata on export, because GPS coordinates can identify a photo's subject as surely as a face can.

How do I anonymize a face in a photo?

Drop the photo in the editor, wait a second for detection, and every face appears outlined and selected. Pick a style — blur, pixel blocks, or a solid bar — and download. Only want some faces hidden? Untick the rest. The whole thing takes under a minute.

Blur, pixelate, or a solid bar — which anonymizes best?

All three are destructive edits in the export. Blur is the most photographic; pixelation reads as deliberate censoring; a solid bar replaces the region entirely and is the strongest choice. The Blur faces and Pixelate a face pages go deeper on the first two.

Can an anonymized face be recovered from the export?

Not from the pixels — the export re-encodes the image with the regions rewritten, so there is no original face hiding under a filter. One honest caveat: very coarse pixelation of tiny regions has been reconstructed in research settings, so use a generous block size — or the solid bar, which leaves nothing to reconstruct.

Does it anonymize every face in a group photo?

Yes — each face is detected as its own region, ten or fifty of them, and all start selected. Keep your friends visible by unticking them; the strangers in the background stay hidden.

Is this face anonymizer free? What's the catch?

Free, no account, no watermark, and the upload auto-deletes within an hour. Blurify stores no face descriptors or biometric data and keeps no library of uploads — the anonymizer is the product, not your photos.

Faces are hidden — is the photo now anonymous?

The pixels are one of three jobs. The file's metadata (stripped automatically here) and the context around the photo — captions, uniforms, a recognizable place — are the other two. The How to anonymize a photo guide walks through all three.

How it works for anonymous.

Drop the photo
JPEG, PNG, WebP, HEIC/HEIF — up to 20 MB. It goes straight to encrypted storage and auto-deletes within an hour.
Every face comes back outlined
AWS Rekognition detects each face separately — group shots included. All of them start selected; untick a face to keep it visible.
Pick the anonymization style, export
Gaussian blur, pixel blocks, or a solid bar, set per face. The export rewrites the pixels and strips EXIF and GPS metadata — the anonymization is in the file, not on top of it.
