Pixelate Image
Add a blocky mosaic to a photo to censor faces, plates, or private details — with an adjustable pixel size and a live preview — all inside your browser.
The Pixelate Image tool covers a photo in a blocky mosaic, right in your browser.
Turn up the pixel size to censor faces or sensitive details, then download. Nothing is uploaded.
How to pixelate an image
- Upload your image. Drag it in or click to choose a file.
- Set the pixel size. Larger blocks mean stronger censorship.
- Check the preview. The mosaic updates as you slide.
- Download. Save the pixelated copy to share safely.
Censor with confidence
Screenshots and photos often reveal things you did not mean to share — a face, an address, an on-screen message. A heavy mosaic makes those details unreadable.
Doing it locally means the sensitive original is never uploaded anywhere, so the private data stays private.
- Private: the mosaic is applied on your device.
- Adjustable: from a light effect to full censorship.
- Permanent: the downloaded copy cannot be un-pixelated.
- Instant: a live preview as you tune the size.

Censorship is often about privacy. To strip hidden location and camera data from a photo as well, the EXIF Viewer & Remover removes its metadata.
If you only need to hide one corner, the Image Cropper can isolate a region first. And to shrink the file before sharing, the Image Converter compresses and converts it.
Frequently Asked Questions
Is my image uploaded to pixelate it?
No. The mosaic is applied on a canvas in your browser, so the image never leaves your device. This matters when you are hiding sensitive details.
Can I control how blocky it looks?
Yes. The pixel-size slider sets how large each block is, from a fine mosaic to heavy censorship where features are unrecognisable.
Is the pixelation reversible?
No. Pixelating permanently discards the original detail in the downloaded copy, which is exactly what you want for censorship. Keep your original file separately.
Does it pixelate the whole image?
Yes, this tool applies the mosaic across the whole image. To hide only one area, crop that region first, pixelate it, and place it back.
What is it good for?
Common uses are hiding faces, license plates, addresses, screen contents, and other private information before sharing a photo or screenshot.
