Pixelate / blur
Drop images and obscure them with pixelation or Gaussian blur. Apply to the whole image, or to a specific x,y,w,h rectangle (e.g. to redact a face or sensitive label).

When to use this tool
Privacy redaction (faces, addresses, phone numbers, account IDs) before sharing screenshots or photos. Pixelate is the more recognisable "redacted" look; blur is gentler and looks more natural.
Step by step
- Use the inspector or any image editor to find the rectangle of pixels to redact.
- Drop the image(s).
- Pick mode (pixelate or blur) and amount. 12 is a sensible pixelate default; 16 for blur.
- Enter the area as
x,y,w,h— or leave blank to apply to the whole image. - Click Apply.
Use cases
- Bug reports. Blur a customer's name in a screenshot before sharing.
- Photos. Pixelate a license plate or face before posting.
- Documentation. Redact API keys in tutorials.
- Whole-image blur. Soft-focus background for text overlays.
FAQ
Is pixelation reversible?
Effectively, no — for sensitive data the result is one-way. (Theoretically, weak pixelation of low-entropy text can sometimes be reversed; use a large block size or switch to a heavy blur for true privacy.)
How do I find the right x,y,w,h?
Drop the image into the inspector or open it in an editor with rulers; the top-left corner is (0, 0).
Is the redaction "burned in"?
Yes — the output is a fresh PNG/JPG/WebP with the redaction baked into the pixels. No layer to peek through.
