Before sharing a scanned ID, a screenshot, or a photo with someone else's face in it, you often need to hide one specific detail — a face, an Aadhaar or PAN number, an account number. Upload your image, click and drag over the area to hide, and this tool permanently pixelates that region by downscaling and re-rendering it, so the original detail can't be recovered from the output file. Everything runs in your browser; nothing is uploaded to a server.
Real redaction versus covering something up
Drawing a black box over sensitive text in a PDF is famously unsafe — the original content is still in the file underneath and can be extracted. Pixelating a region of an image is different in kind: the selected area is downscaled to a coarse grid and redrawn, and the output is a freshly rasterised image with no trace of the original pixels anywhere in the file. There is no layer to peel back because the detail was destroyed rather than hidden.
What to hide before sharing
The common cases are faces of people who did not consent to being posted, and identifying numbers on documents — Aadhaar, PAN, account numbers, addresses on a utility bill being used as proof. Select generously rather than tightly: partial digits can often be inferred, and a number that is half visible is not protected. If several separate areas need hiding, apply the blur, then re-upload the result and blur the next area.
Check the result before you send it
After applying, the tool shows the blurred image so you can confirm the selection actually covered what you intended. This is worth genuinely looking at rather than skimming — a selection that missed by a few pixels leaves the first or last digit of a number readable, which can be enough. The blur is permanent in the output, so keep your original if you might need the unredacted version later.
Frequently asked questions
- Is the blurred detail really unrecoverable, or just visually hidden?
- The selected region is downscaled to a tiny grid and redrawn — the output file is a freshly rasterized image with no trace of the original pixel data underneath, unlike drawing a box over text in a PDF (where the original content can still be extracted from the file).
- Can I select more than one area?
- This tool handles one selection per pass — apply the blur, then re-upload the result to blur a second area if needed.
- Can I undo after applying the blur?
- No, once applied the pixelation is permanent in the downloaded file — keep your original photo if you need it again.
- Are my photos uploaded to a server?
- No — that's the point of this tool. Processing happens locally in your browser; the original image never leaves your device.
- Can the blurred area be reversed?
- No. The pixel data in that region is destroyed and replaced, so there is nothing in the output file to recover it from.
- Can I blur several areas at once?
- One selection per pass. Apply the blur, then re-upload the result to blur the next area.
