# Pixelate or blur part of an image

Cover faces, names or numbers by pixelating or blacking out a region.

## How it works

Drag a rectangle over the part of an image you want obscured, and pixelate it, blur it or black it out. The image never leaves your browser, which matters more here than for most tools.

Black boxes are the only reliably safe option. Pixelation and blurring have both been reversed — for text especially, where the character set is small and known, depixelation attacks recover the original with high accuracy. A pixelated house number or licence plate should be treated as visible, not hidden.

This tool destroys the pixels rather than covering them, so the underlying data is genuinely gone from the output file. Drawing a black rectangle over a region in a PDF or an office document usually does not do that — the original content stays in the file underneath the annotation, and that has caused a long series of real-world leaks of supposedly redacted documents.

Metadata is separate. Removing a face from the image does not remove the GPS coordinates in the EXIF header, so use the metadata tool as well when it matters.

> This tool runs entirely in your browser. Nothing you enter is sent to a server, logged or stored, and the page keeps working with the network disconnected.

## Common questions

### Is pixelation safe for redaction?

No. Pixelation and blurring have both been reversed, especially for text where the character set is small. Use a solid block for anything sensitive.

### Is the hidden content really gone?

Yes here — the pixels are overwritten before encoding. Black rectangles drawn over PDFs and documents often leave the original text in the file underneath.

### Does this remove location data?

No. That lives in the EXIF metadata, which is separate from the pixels. Strip it with the metadata tool.
