🫥Blur / Pixelate Region

Sellers publish more sensitive images than they realise: a screenshot of an order confirmation with a buyer's address, a warehouse photo with a supplier's label and price, a lifestyle shot with a car number plate, or a customer review picture with a child in the background. The Blur / Pixelate Region tool lets you blur part of image content or pixelate image online with precise control over what is hidden, and then apply the same regions to a whole batch of similar images. It is a censor image tool that keeps the rest of the photo sharp.

How it works

1. Drop one image, or a set that shares the same layout, such as screenshots from the same app.
2. Draw regions on the preview: drag a rectangle or an ellipse, or paint freehand with the brush for irregular shapes.
3. Pick an effect per region: Blur (Gaussian, with a strength slider), Pixelate (block size in pixels) or Solid (an opaque colour bar).
4. Adjust, move or delete regions until only the sensitive parts are covered.
5. Process. In batch mode the regions are stored as percentages of width and height, so they land in the same relative place on every image, then download the ZIP.

Regions are applied at full resolution, not on the preview, so a small blur on the screen is a proportionally small blur on a 4000 px original.

Why it matters

Hiding information is not the same as hiding it well, and the wrong method can be undone.

• Light blur on text can be partially recovered by comparing against candidate strings; for anything that must stay secret, use pixelate with blocks of at least 12 to 16 px or a solid bar.
• Pixelation of faces with large blocks is irreversible in practice, but a slight blur is not, so when you blur face in photo content for privacy, use strong settings.
• Marketplaces have their own rules: Amazon and Daraz forbid promotional text, phone numbers and watermarks on product images, so covering a supplier's contact details is often required, not optional.
• Data-protection law in the EU, the UK and many other regions treats faces, plates and addresses as personal data. A review screenshot used in an ad without redaction is a complaint waiting to happen.

Blur and pixelate also have a softer use: obscuring a not-yet-released product in a teaser, or hiding a competitor's brand in a comparison image.

Tips

• Use Solid for addresses and order numbers, Pixelate for faces and plates, and Blur only where the goal is aesthetic softening rather than secrecy.
• Extend regions a few pixels beyond the text or face; edges reveal more than you expect.
• For batches of screenshots, take them at the same zoom and window size so regions align.
• If every face in a photo needs hiding, the Face Blur (Auto) tool finds them automatically.
• Cropping is sometimes cleaner than blurring; the Image Cropper can simply remove a sensitive margin.
• Remove the GPS and camera data too with the EXIF / Metadata Remover, and use the Watermark Tool if the goal is discouraging copying rather than hiding data.
