Free tool
Pixelate part of an image
Censor sensitive information in screenshots and photos — API keys, faces, addresses, spoilers. Drag a rectangle and it gets pixelated, blurred, or covered with a solid bar. Then download. Your image never leaves your device — everything runs in your browser.
Drag a rectangle over anything you want to hide. Each selection is censored instantly with the selected mode — mix pixelation, blur and bars freely in one image.
How it works
- Drop in an image, browse for a file, or just paste a screenshot with ⌘V / Ctrl+V.
- Pick a mode — pixelate, blur, or black bar — and drag a rectangle over anything you want to hide. Each selection is censored instantly, and you can mix modes freely in one image.
- Download the result as a lossless PNG. The hidden areas contain only averaged blocks, blurred color, or solid fill — the original detail is gone from the file.
Why no-upload matters
Most online pixelation tools send your image to their servers to process it — which is a strange thing to do with a screenshot you're censoring precisely because it contains secrets. This tool is different by construction: the image is opened, edited and saved entirely on your device using your browser's canvas. There is no upload, no processing queue, no copy of your image anywhere but your own machine.
Frequently asked questions
Is my image uploaded to a server?
No. The entire tool runs in your browser — the image is loaded, censored and saved locally on your device. Nothing is transmitted anywhere, which is exactly what you want when the image contains sensitive information.
Should I pixelate, blur, or use a black bar?
For text, pixelate with a block size at least as large as the text height — once a whole character collapses into one square there is very little shape left to read. Blur looks softer and suits faces and backgrounds, but weak blur on text can be partially reconstructed, so turn it up or switch to pixelation when the content matters. A black bar is the blunt instrument: nothing survives it, and it looks like nothing survived it.
Can the censoring be reversed?
Pixelation and bars performed here are destructive: the downloaded PNG contains only the averaged blocks or the solid fill, not the hidden pixels. For highly sensitive data, use a larger block size or a bar, and censor a slightly larger area than strictly necessary.
What image formats are supported?
Anything your browser can open — PNG, JPG, WebP, GIF (first frame), AVIF and more. The result always downloads as a lossless PNG.
Is it really free?
Yes — free, no signup, no watermark, no limits. Because everything runs on your device, it costs us nothing to offer, so there's no catch.
Censoring something specific?
The blocks you just dragged out are the same thing minia.art makes on purpose — type a prompt and get pixel art back: sprites, scenes, icons, avatars, looping animations. Try it free — 20 generations a month, no credit card.
