PNG, JPG, WebP — the image stays in your browser
Pixels are averaged in blocks — that is why details disappear instead of just looking smaller. The preview is rendered at screen size for speed; the export runs the same calculation over the full-resolution image, so a large photo may take a second.
About Pixelate Image
Pixelate a whole image: drag the slider to pick a block size, the preview follows live, download the PNG when it looks right.
The method is averaging inside blocks, not blurring. The picture is cut into N×N squares and each is filled with its average colour — detail is genuinely discarded rather than smeared. That makes it a better fit than Gaussian blur for hiding ID numbers, plates and faces, where nothing should remain recoverable.
Pixelation is not magic, though. At small block sizes (4–6 px) outlines and shading survive, and AI reconstruction tools can make a decent guess at what was behind it. For passwords or ID numbers, go past 16 px — or cover the area with solid black.
Preview and export are two separate passes: the preview runs at screen size for speed, the export re-runs the same block grid at full resolution, so downloading a large photo may take a second. They match visually.
The output is lossless PNG, so saving does not cost another generation of quality. The whole image is processed — this version has no region selection (say the word and it can be added).
It all runs in the browser; the image is not uploaded.
Frequently asked questions
Can pixelation be reversed?
With large blocks (16 px and up) essentially no. At small sizes the outline survives and AI reconstruction can make a guess.
Can I pixelate just one area?
This version processes the whole image. Region selection can be added if needed.
Why does the preview look like a different block size?
The preview scales the block size to screen size; the export recomputes on the full resolution. The visual proportion matches.
What format is the output?
Lossless PNG. Convert it with the image converter if you need a JPEG.
Is the image uploaded?
No, everything runs on a canvas in the browser.
