Selected areaPixelate faces and private details
Choose Selected area and draw a rectangle around the whole face, from forehead to chin. This example uses 32 px blocks. You choose the area to cover; the shirt and park stay clear.
Pixelate a license plate
Draw a rectangle that includes every character and the edges of the plate. Here, 24 px blocks cover the sample plate. Open your downloaded photo at full size to check the result before sharing it.
Pixelation makes details harder to recognize, but does not guarantee they cannot be recovered. For passwords, account numbers, or confidential text, solid color redaction is safer.
Pixelated effect examples
The same 1536 × 1024 px photo at four block sizes, displayed at the same scale. Compare the roof edges and trees to see how much detail each setting retains.
Start at 16 px for visible texture, or try 32–64 px for a bold mosaic. Your photo keeps its original width and height at every setting.
What is image pixelation?
Image pixelation is an effect that replaces groups of pixels with larger blocks of color, creating a blocky or mosaic appearance. It can be used for visual effects or to make selected details harder to recognize.
Make something pixelatedPixelation vs. blur:
what’s the difference?
| Pixelation | Blur | |
|---|---|---|
| Method | Groups pixels into blocks | Blends adjacent pixels |
| Look | Sharp, mosaic squares | Soft, smooth shapes |
| Control | Pixel block size | Blur radius |
| Use | Retro effects, obscuring details | Soft backgrounds, obscuring details |
This tool applies pixelation, not blur. Neither replaces secure redaction.
Frequently
asked questions
Can I undo my edits?
Use Undo to go back through your last 40 changes. Reset keeps your photo but applies 16 px blocks to the whole image again. Choosing a different photo clears your previous edits.
Can I pixelate just part of an image?
Yes, you can pixelate one rectangular area at a time. To select without dragging, choose Select center area, then adjust Left, Top, Width, and Height. Each number is a percentage of the image. Drawing a new rectangle replaces the old one.
How do I make a photo more pixelated?
Increase Pixel size, up to 100 px. Larger photos usually need larger blocks for a noticeable effect, especially when you view them on a small screen.
Can I pixelate a picture for free?
Yes. All editing and downloads are free, with no account or watermark.
Which download format should I choose?
Choose PNG to keep transparent backgrounds and avoid extra compression that can reduce detail. JPG works well for photos, but turns transparent areas white. WebP keeps transparency and often gives you a smaller file. All three keep your photo’s original width and height.
Are my uploaded images private?
Your photos stay on your device while you edit. We do not receive or store them. Download your finished photo before refreshing or closing this page, or your edits will be lost. Files you have already downloaded stay on your device.
Which files and image sizes can I use?
Use JPG, PNG, or WebP files up to 25 MB and 32 megapixels, with neither side longer than 8192 pixels. Some phones and computers may struggle with large photos. If a photo will not open or download, try a smaller copy.
