What does Blur & Pixelate do?

Before you post a screenshot or a photo, it often contains something that should not be public: faces of people who did not agree to appear, a car's number plate, a house number, a name on a delivery label, an e-mail address, a bank detail or a QR code. This tool lets you hide those areas by drawing boxes over them and choosing how to cover them.

Three ways to hide information

  • Pixelate replaces the area with large coloured blocks – the classic look used on television.
  • Blur smooths the area with a strong Gaussian-like blur, which looks softer and more natural in photos.
  • Black box covers the area with solid black. This is the only method that removes the information completely, so use it for text, numbers, passwords, QR codes and documents.

The strength slider sets the block size or blur radius relative to the image, so the effect looks the same in the preview and in the full-size download. For privacy, stronger is safer: light pixelation or blur of short text can sometimes be guessed or partly reversed.

Marking areas

Drag on the preview to draw a box around each area; you can mark as many as you need. Undo removes the last box and Clear areas removes them all. Whole image applies the effect to the entire picture, which is useful for blurred backgrounds or spoiler-free previews. The dashed outlines are only guides and do not appear in the saved image.

Private by design

It would be self-defeating to upload a sensitive picture to a website in order to hide its sensitive parts. Here the image is processed on your device: it is never uploaded or stored, and the downloaded copy contains no trace of the original pixels in the covered areas.

How to blur part of an image

  1. Drop your image, choose it or paste a screenshot with Ctrl+V.
  2. Pick Pixelate, Blur or Black box and set the strength.
  3. Drag over each area you want to hide.
  4. Click Save image and download the censored copy.

Frequently asked questions

Is the metadata removed too?

Yes. The image is re-encoded, so EXIF data such as GPS location is not included in the result.

Can I blur a face automatically?

Not yet: you mark each area yourself, which also means nothing is missed by mistake.
