Hide faces, text and numbers in a picture. Runs on your device.
Solid block paints the area in one flat colour, black to start with. Nothing of the original is left under it, so it is the choice for a password, an ID or account number, an address or a face you must not show. Pixelate cuts the area into square cells and gives each cell the average colour of the pixels in it. Blur smears the area softly. Both keep a rough impression of what was there, which is why they look more natural on a face in a holiday photo and why they are the wrong choice for anything sensitive. Each region has its own effect, so one picture can have a solid block over a card number and a blur over a bystander. Regions are applied in the order of the list, each on top of the one before.
A blur or a coarse pixelation does not delete information, it mixes it. Short text, a number plate or a small face can sometimes be partly recovered when the blur is light, because the mixing follows a known pattern and software can work backwards from it. A bigger block size or a larger blur radius makes this harder, but nobody can promise where the safe point is for a given picture. Solid block has no such problem: the pixels are replaced, not changed, so there is nothing to work back from. This page says so next to the effect choice for that reason. If a picture would cause harm in the wrong hands, use Solid block, and pick a block size or radius only for pictures where a soft look matters more than certainty.
The file you download is drawn again from pixels and saved as a new image. The original pixels under every region are replaced in that new image, and the old ones are not stored anywhere in it. The camera details, the GPS location, the capture time and the other metadata that phones and cameras write into a photo are not copied, so they are gone too. A JPEG is saved as a JPEG at quality 0.92; a PNG or WebP is saved as PNG. The picture keeps its pixel size unless it is larger than your device can handle, and the page tells you before you save. The rotation flag that phones store is applied first, so the regions land on the same content you saw. A transparent PNG under a solid block becomes opaque in that area.
Your picture is opened by your browser's own image code and drawn on a canvas inside this tab. There is no upload step and no server that receives pictures. The page counts visits with Google Analytics; those counts say which tool was opened, never a file name, an image, a position or a size. While you work, the page shows a smaller copy so dragging stays smooth; when you save, the full-size picture is opened again and the regions are applied to it. Memory sets the limits: single images up to 100 megapixels, or 50 on a phone. This tool does not find faces or plates by itself, and it does not work on PDFs; to hide something on a PDF page, turn the page into an image first and hide it there.
Sometimes, in part. A light blur or fine pixelation over a short number, a licence plate or small text can be partly recovered by software. A solid block cannot, because the pixels are replaced. For a password, an ID number or an address, use Solid block.
No. The file is drawn again from pixels, so the GPS location, camera model and capture date from a phone photo are not in it. A JPEG comes out as a JPEG at quality 0.92, and a PNG or WebP comes out as a PNG.
No. You draw each rectangle yourself. There is no detection, so check every face or plate in the picture before you share it. A new image opens with one example area in the middle, which you can move, resize or delete.
Not here. This tool works on JPEG, PNG and WebP. To hide text on a PDF page, turn the page into an image with the PDF to JPG tool, hide the area on the image, then turn the image back into a PDF. The text is then a picture, so it cannot be selected.
Touch and drag on the picture to draw a rectangle. Drag a rectangle to move it, or one of its handles to resize it. Each handle has a 44 pixel touch area. Touch outside the picture to scroll the page. The Undo and Redo buttons keep up to 100 steps.
Yes. Choose Add region, then press an arrow key to move the region by about 1 display pixel. Shift with an arrow resizes it, Alt makes each step ten times larger, and Delete removes it. Ctrl or Command with Z undoes the last step.
