Q: Can a pixelated image be reversed or unblurred?

No. Pixelation replaces the original pixels in a block with a single averaged color, permanently destroying the detail. Once you download the pixelated image, the covered information cannot be recovered from that file.

Q: Is my image uploaded to a server?

No. All processing happens locally in your browser using the HTML Canvas API. Your image never leaves your device, so there is nothing for us to store or see.

Q: What image formats are supported?

You can load PNG, JPEG, and WebP images, and export your result as PNG, JPEG, or WebP at the original resolution.

Q: What is the difference between pixelate and blur?

Blurring smoothly smears pixels together, while pixelation replaces areas with large solid blocks (a mosaic). Pixelation is generally harder to reverse and is the standard choice for hiding faces, license plates, and sensitive text.

Drop a photo, drag to select an area (or auto-blur every face), and download — all in your browser. No upload, no sign-up, no watermark.
