Pixelated
Deliberate square blocks, not a soft blur
The painted area is reduced to a coarse grid and enlarged with smoothing disabled. Everything outside the brush mask remains unchanged.
- Start with the full image
- Get an immediate result without drawing a selection first.
- Paint any shape
- Switch to selected-area mode and brush over one or several details without forcing them into a rectangle.
- Choose block size
- Use smaller blocks for a light mosaic or larger blocks for stronger visual abstraction.
- Keep the rest untouched
- Brush processing redraws only the painted mask and preserves the rest of the image.
Pixelate an image in three steps
Always review the final export at its intended display size before treating pixelation as privacy protection.
- 1
Upload the image
Choose the photo or screenshot that needs a visible mosaic treatment.
- 2
Paint the area and set blocks
Use the whole image or brush over every detail to hide, then adjust block size from 4 to 128 pixels.
- 3
Review and export
Confirm the intended detail is sufficiently obscured, apply the edit, and download the PNG.
Obscure a detail or create a blocky visual style
Pixelation is manual and visible. Blur Faces remains the better tool when faces should be found automatically.
Screenshots
Cover one account number, address, message, or interface detail before sharing.
Creative effects
Turn the full image into an intentionally blocky graphic or low-resolution treatment.
Background details
Reduce the readability of one sign, label, or small area without blurring the entire frame.
Pixelation must be reviewed for the actual privacy risk
A mosaic changes visible pixels but no fixed block size can guarantee that every kind of underlying information is unrecoverable.
- Use larger blocks and inspect the exported result at the size where it will be shared.
- The brush supports multiple freehand strokes; automatic object detection is not included.
- Use Blur Faces for automatic face privacy and Unpixelate Image only for improving already blocky images.
