Can I pixelate only one area?

Yes. Choose area mode and draw a rectangle over the region to pixelate.

Will output size change?

No. The mosaic is scaled back to the original width and height.

No. Pixelation is entirely client-side.

Is this image tool free to use?

Yes. You can use this tool directly in your browser for free, without account creation or hidden upload limits.

Do my files leave my device?

No. Processing happens locally in your browser, so your files stay on your device and are not uploaded to our servers.

Will the output match the preview?

Yes. The preview is scaled for display, but exports use the original image resolution and the same processing settings you chose.

What is Pixelate?

Block-pixelate the full image or a selected rectangle with an adjustable block size. Great for redacting details or creating mosaic effects while keeping output dimensions unchanged.

Trust and privacy are built into the workflow. No files leave your device during processing, and there is no account setup required. That makes Pixelate suitable for personal photos, client assets, product images, and everyday creative work.

How to use Pixelate

Upload or drag your image into the tool above.
Adjust the editing controls until the live preview looks right.
Choose an output format (and quality when relevant).
Download the edited image — processing stays on your device.

Tip: preview at a comfortable zoom, then export once you are happy — repeating lossy saves can add compression artifacts.
