Pixelate Image Online Free

A pixelate image tool replaces part of a picture with large square blocks, the mosaic effect used to censor faces and text. Here you draw one rectangle, pick a block size and download a copy where only that rectangle is pixelated.

1. Click Choose files and pick your image. 2. Drag a box over the face, plate or text. 3. Set Effect strength to choose the block size. 4. Check the live result and click Download to save the image.

Raise Effect strength. The value is the width of each block in pixels, so 12 gives roughly 12-pixel squares and 40 gives much chunkier ones. Values are kept within 2–100.

Not by this tool, and large blocks remove most detail. Researchers have shown, though, that short and predictable text under small blocks can sometimes be guessed. Use a big block size, cover the whole item, and crop out anything truly sensitive.

Yes. Type 0 for both positions and 100 for both area sizes, and the entire picture turns into blocks. It’s a quick way to make a pixel-art style background or a deliberately unreadable preview.

Yes. You don’t need an account, and the exported image carries no SocQ branding or watermark. Use it as often as you need, on desktop or mobile.

No. Pixelation runs on a canvas in your browser and the result is generated locally. Your image isn’t uploaded to SocQ, which is useful when the picture contains private details.

JPG, PNG, WebP and AVIF images up to 30 MB and 40 megapixels each. A JPG is saved as a JPG at 90% quality and other formats as PNG, both at the original width and height; in a PNG the rest of the image keeps its full quality.

You can pixelate up to 20 images at once with the same box, then save them with Download ZIP. Each pass handles one rectangle; for a second area, open the downloaded image again and pixelate the next spot.

Both hide identity when the setting is strong enough. Pixelation looks like obvious censoring and is easier to judge at a glance, while blur looks softer and blends into lifestyle photos. Check the result at full size either way.
