Hide a face, a number plate, an address on an envelope or an account number on a screenshot. The pixels underneath are replaced rather than covered, so there is nothing left to uncover.
Anything you are about to send, post or attach to a complaint. It is opened here on your device.
Choose blur, pixelate or a solid block, set the brush size, and drag over the part you want gone. Undo steps back if you go too far.
You get a PNG with the obscured areas baked in. Send that one and keep your original.
People have leaked the exact thing they meant to hide by drawing a black box over it in an editor and saving a file that still had the original underneath. Anything that keeps layers, and several phone editors do, means the covering can be peeled back off.
This flattens the picture as you paint. Each stroke reads the pixels that are there, replaces them with a blurred or pixelated version of themselves, and writes that back. By the time you save there is no hidden layer, because there never was one.
A word on pixelation. A coarse mosaic over a face is genuinely hard to reverse, but a light mosaic over a short, predictable string, a six digit code or a number plate, is weaker than it looks, because there are few enough possibilities to work through. If what you are hiding is short and guessable, use a solid block.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
Practical limits depend on the tool, browser and available device memory. Large files can fail even when no explicit limit is shown. Keep an original and use a smaller job if this device cannot finish it.
No, and there is no daily limit either. There is nothing to sign up for.
Not from the file you save. The pixels are replaced before the file is written, so the detail is not in there to recover.
Blur for faces and backgrounds, pixelate when you want it to be obvious something was hidden, and a solid block for anything short and guessable like a code or a number plate.
So the rest of the picture stays sharp. JPG would add its own softening to text and screenshots, which is the opposite of what you want on the parts you are keeping.
Paint over a face, a number or an address and choose how it is hidden: blur, pixelate or a solid block. You set the brush size and, for blur and pixelate, the strength. The pixels are replaced in the picture itself, so what was underneath is not in the saved file as a hidden layer.
You can undo your last dozen strokes, and the save button stays off until you have painted something, so you cannot save an unchanged picture by mistake.
For text and numbers, use the solid block. A light blur or a fine pixelation on small print can sometimes be guessed back, and a block cannot be. Blur and pixelate are fine for faces and for general softening.
The picture you work on is limited to 1600 pixels on its longest side, so a very large photo is saved at that size. The result is always a PNG, and camera details such as the location are not carried over. The brush is freehand, and there is no automatic face detection.
