How does the pixelation process work?

The pixelation process works by downsampling your image to a lower resolution (dividing dimensions by the pixel size) and then scaling it back up. For example, with an 8px pixel size, a 800x600 image becomes 100x75, then is scaled back to 800x600, creating 8x8 pixel blocks.

What image formats can I upload?

You can upload common image formats including JPG, JPEG, PNG, GIF, and WEBP. The tool processes images client-side, so there are no file size restrictions beyond your browser's capabilities.

In what formats can I download my pixelated image?

You can download your pixelated image in three formats: PNG (best for quality and transparency), JPG (smaller file size, good for photos), and WEBP (modern format with excellent compression).

Is my image stored on your servers?

No, all image processing happens entirely in your browser. Your images are never uploaded to our servers, ensuring complete privacy and security. The pixelation algorithm runs locally on your device.

Is this safe to use this pixelated image generator?

Yes. This tool follows a privacy-first approach: pixelate and blur run only in your browser. There are no server uploads, so the original image is not sent to our servers, stored, or shared. You can edit and download locally on your device.

Can I use it for sensitive images?

Yes. Because conversion happens only in the browser, no image data leaves your device. Faces, IDs, documents, and other sensitive photos stay private on your computer — nothing is uploaded to a server.

Is this tool free to use?

Yes. The Pixelate Image Generator is 100% free. You can pixelate or blur images, use multiple selections, and download the result with no account, watermark, or paid plan required.

What pixel size should I use?

The ideal pixel size depends on your goal: Use 1-4px for subtle effects, 8-16px for noticeable pixelation, and 32-64px for extreme retro effects or strong privacy protection. Start with the presets and adjust the slider to fine-tune.

Can I use pixelated images commercially?

Yes, you can use pixelated images created with this tool for any purpose, including commercial use. However, make sure you have the rights to the original image you're pixelating.

Does pixelation reduce image file size?

Pixelation can reduce file size when using formats like JPG or WEBP, as there's less detail to compress. PNG files may remain similar in size. The actual file size depends on the pixel size, original image complexity, and chosen format.

Overview

How image pixelation / blur image works?

Pixelation groups nearby pixels into larger blocks so details become unreadable. Blur softens the same area instead. Use either effect to hide faces, IDs, or other sensitive spots while keeping the rest of the photo clear.

Add one or more selections, then set Pixelate or Blur, Rectangle or Circle, and amount for each area. The preview updates as you move or resize the markers.

JPG, PNG, WebP, and similar images stay on your device. Need a tighter frame first? Use the Image Cropper.
