Blur or Pixelate an Image
Hide what should not be shared — a face in a crowd, a licence plate, an address on a screenshot. Drag a region and apply blur or pixelation, repeat for as many areas as you need, and download. Sensibly for a censoring tool, the photo never leaves your device.
100% private — this tool runs in your browser. Your file is never uploaded to any server.
How it works
Drag a rectangle over the area to hide, press Apply, and the effect is baked into the image at full resolution — then drag the next region and apply again, as many times as needed. Leave the image untouched by a selection and Apply censors the whole picture instead. The effect is destructive on purpose: the download contains the blurred or pixelated pixels themselves, with the original detail genuinely absent, unlike cropped-out regions in some document formats that travel along hidden. One honest note on strength: modern software can sometimes reconstruct text from light pixelation, so for anything sensitive — documents, plates, faces you must protect — choose Strong, which discards far more information than any reconstruction can recover.
Step by step
Add your image
Drop a photo or screenshot, or tap to choose.
Select a region
Drag a rectangle over what should be hidden — or select nothing to affect the whole image.
Apply
Pixelate or blur is baked in at full resolution. Repeat for more regions.
Download
Save the censored copy — the hidden detail is not in the file.
Frequently asked questions
How do I blur just one part of a photo?
Drag a rectangle over that part and press Apply — only the selected region changes. Then drag the next area and apply again; each application is baked in, so you can censor several spots in one session.
Pixelate or blur — which hides things better?
Pixelate at Strong is the safer choice for text and faces: it reduces the region to large flat blocks that carry almost no recoverable detail. Light blur, by contrast, can sometimes be partially reversed by modern reconstruction software. When it truly matters, use Strong.
Can someone undo the blur and see what was there?
Not from the downloaded file if you used Medium or Strong — the original pixels are replaced, not hidden. The realistic risk is Light applied to text, where reconstruction tools have had some success. This is exactly why the strength setting exists.
Why is a censoring tool that uploads photos a bad idea?
Because the moment your photo reaches someone’s server, an unredacted copy exists outside your control — the very thing censoring was meant to prevent. This tool does the work in your browser precisely so that no such copy is ever created.
Can I blur a face in a group photo without affecting the rest?
Yes — that is the main use. Drag a tight rectangle around the face, choose Strong pixelate, and apply. The rest of the photo keeps its full original sharpness.
I applied the effect in the wrong place — can I undo it?
Re-add the file (drop it again) to start from the clean original. Applications are baked in as you go, so there is no step-by-step undo — work from the most important region to the least.
Does the effect reduce quality outside the selected region?
The untouched areas are copied at full resolution. Saving a JPG re-encodes once at high quality, which is not visible; a PNG source saves losslessly with the alpha channel intact.
What is the difference between this and cropping the area out?
Cropping removes the area and changes the picture’s framing; censoring keeps the composition and hides only the detail. For an ID photo where the layout must stay recognisable — or a screenshot where context matters — censoring is usually what you want.
