Pixelate an image or selected area
Use the image pixelator to create a blocky mosaic effect without opening Photoshop or another desktop editor. You can pixelate the full image, a rectangular selection or a custom area painted with the brush.
Pixelation works well when you need to visibly censor text, faces, identifiers or other details before sharing an image online.

How to pixelate an image
Pixelating a photo takes four quick steps.
Select an area
Choose Whole image, Rectangle or Brush depending on what you want to pixelate.
Set the pixel size
Use smaller blocks for a subtle effect or larger blocks to hide more detail.
Export the image
Download your pixelated image as JPG, PNG or WebP.
Use cases
When to use image pixelation
Censor sensitive details
Pixelate text, addresses, contact details, account numbers or other information that should not be readable.
Hide faces and identifiers
Cover a face, license plate, badge or username with clear mosaic blocks.
Create a pixel-art look
Apply larger pixels to the whole photo for a stylized low-resolution effect.
Edit only one area
Pixelate part of an image while leaving the rest sharp and unchanged.
Blur ↔ Pixelate
Pixelate vs blur
Pixelation creates visible square blocks and clearly signals that an area has been censored. Blur produces a softer effect and is often better for subtle visual focus.
Try the Blur Image tool →Local processing
Pixelate privately in your browser
Your photo is processed locally by your browser. BlurringTool does not need to upload the image to a server to create the pixelation effect.
