Result

This page opens the blur tool in pixelate mode for censoring photos and screenshots — drop in the image, drag rectangles over everything that must stay private and download the cleaned copy.

Mosaic pixelation is the standard way to redact documents, chat screenshots, license plates, addresses and account numbers: each marked block is replaced by its average color, so the original text is destroyed rather than just dimmed. Keep the block size large for text — small mosaics on high-resolution screenshots can sometimes be partially reconstructed.

You mark every region yourself, so nothing is missed and nothing extra is hidden. The photo is processed locally in your browser and is never uploaded anywhere.

Executed in Browser

Your files and inputs never leave this device. Processing runs completely offline. 100% Secure.

Accepted Formats & Rules

Draw any number of rectangular regions with the mouse or a finger, with a removable region list.
Two censoring modes: blur with adjustable strength or pixelate with adjustable block size.
One-click button to select the entire photo, plus an honest live preview of the final effect.

Key Benefits

✓ 100% Client-Side: the photo is censored entirely in your browser and never uploaded anywhere.

✓ You stay in control: you draw every region yourself, so exactly what you mark gets hidden — no guesswork.

✓ Real pixel effects: multi-pass box blur and true mosaic pixelation are baked into the downloaded file.

Use Cases

• Do you need to blur a stranger's face or your child's face before posting a photo publicly?
• Do you want to pixelate a license plate, an address or a name on a photo or screenshot?
