Pixelate Image Online — Mosaic Censor for Photos
Censor part of a photo with a classic pixelated mosaic effect. Pixelate Image is ideal when you want an obvious block-style hide — faces on TV news, sensitive data in screenshots, or anonymized identities in reports. Draw square or circle regions, control block size, and export PNG without sending your file to the cloud.
How to use this tool
- Open Pixelate Image and upload your JPG, PNG, or WebP file.
- Click Square or Circle and place the shape over the content to censor.
- Resize the shape with corner handles and move it by dragging inside.
- Use the intensity slider to increase or decrease pixel block size.
- Download your pixelated PNG when the censor looks right.

Frequently asked questions
- What is the difference between pixelate and blur?
- Pixelate replaces detail with visible square blocks (mosaic censor). Blur softens detail with a smooth out-of-focus effect. Choose pixelate for obvious redaction; choose blur for subtle privacy.
- Can I control how blocky the pixelation looks?
- Yes. The intensity slider adjusts block size — lower values create finer pixels; higher values create larger mosaic squares.
- Can I pixelate multiple areas in one image?
- Yes. Add as many square or circle regions as you need and adjust each one independently.
- Is pixelating images online free?
- Yes. Reels Editor's Pixelate Image tool is free with no account and no watermark on exports.
- What formats can I upload?
- JPG, PNG, and WebP uploads are supported. Downloads export as PNG.
