Pixelate Image
Create a blocky mosaic effect across a photo. Change the block size to move from a subtle pixel texture to a strongly abstracted image.
- Adjust the pixelation block size
- Apply the effect across the full image
- Keep the source image’s outer dimensions
Choose the block scale
Smaller blocks retain more recognizable detail. Larger blocks replace wider areas with coarse color patches.
Build a deliberate graphic effect
Pixelation can simplify a busy photograph into a background or stylized image. Compare the result at the intended viewing size.
Keep geometry separate
The effect changes how the image looks, not its composition. Crop or resize first if the final output needs different boundaries.
Do not use it as secure redaction
Pixelation can leave information inferable. For confidential text or faces, use an appropriate irreversible redaction process instead.
Pixelate Image FAQs
This page applies pixelation to the entire image, not a selected region.
Not necessarily. Encoding and image format also determine output bytes.
Increase the block size until the desired level of detail disappears. The effect covers the entire image, so use a crop first if you only want a smaller composition. Do not rely on pixelation to securely hide confidential text or identities.
