Pixelate Image
Pixelate Image — instantly, in your browser, with nothing uploaded.
Drag & drop your image here, or click to choose. Everything runs in your browser — nothing is uploaded.
Pixelating replaces blocks of pixels with their average colour, which is the standard way to obscure faces, number plates, addresses and account details in a screenshot before sharing it. Choose the block size and the preview updates live.
Frequently Asked Questions
How do I use the pixelate image tool?
Drop your image onto the box above, adjust the controls, and the preview updates as you drag. When it looks right, choose PNG, JPG or WEBP and press Download. Nothing is uploaded at any point.
Are my files uploaded to a server?
No. The file is decoded and re-encoded directly in your browser using JavaScript and WebAssembly, and never leaves your device. That is what makes it safe for private photos, client work and anything confidential, and it is why the tool keeps working with your network disconnected once the page has loaded.
Is pixelation safe for hiding sensitive information?
Only with large blocks. Lightly pixelated text can sometimes be recovered, because a small block still carries a lot of information about what was underneath. For anything genuinely sensitive use a large block size, or cover the area with a solid shape instead.
Is there a limit or a watermark?
No limits, no watermark, no signup and no cost. Because the work happens on your own device there is no server bill to cover, so there is nothing to meter — the only real constraint is your device’s memory on very large files.
Does this work on Windows, Mac, iPhone and Android?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install and no account needed. Chrome, Edge, Firefox and Safari are all supported.
