Photo Censor is a free image tool that runs entirely in your browser — pixelate, blur or black out parts of an image. No upload, no account, no limits.
Hide parts of an image before you share it. Drop in a screenshot or photo, drag a rectangle over anything that should not be visible, and it is covered immediately — as pixelation, as a blur, or as a solid black box. Areas stack up as you go, with undo for the last one and a clear for all of them.
The censoring is baked into the pixels, not laid over the top: the file you download has had the original detail destroyed in those regions, so there is no hidden layer to peel back the way there is with a highlight in a PDF or a shape pasted over a slide. And, like every image tool here, the picture is processed on canvas in your own browser and never uploaded.
The black box. It replaces the pixels outright, so nothing about the original survives. Pixelation and blur discard most of the detail but not all of it, and researchers have recovered text from lightly pixelated images before — they are fine for faces or background clutter, and the wrong choice for an account number.
No. The regions are drawn into the image itself and then exported, so the download contains no original pixels underneath and no separate layer — unlike a black rectangle pasted over a PDF or a slide, which can often simply be moved.
Never. It is decoded and redrawn on a canvas in your browser, which you can confirm by disconnecting from the network — the tool keeps working.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
