What is Pixelate or blur?

Before sharing a screenshot or a photo, it is wise to cover what shouldn't be seen: other people's faces, license plates, addresses, phone numbers or bank details. This tool lets you censor just those areas.

You paint over them with a brush or draw a rectangle, and the chosen part is pixelated or blurred. If you make a mistake, you undo the last stroke; the rest of the image stays intact.

How to use it

  1. Drag in the image you want to censor.
  2. Choose the effect, “Pixelate” or “Blur”, and its strength.
  3. Select “Brush” and set its size, or “Rectangle” for straight areas.
  4. Paint or drag over the areas you want to hide; use “Undo” if you make a mistake.
  5. Click “Download image”.

Technical details

The effect is generated on a full copy of the image and composited with a mask made from the brush strokes (round stroke with a configurable radius from 1 to 100) or rectangles. Pixelation shrinks the image into blocks whose size grows with the strength (from 2 px up to about 1/22 of the longer side) and enlarges it again without smoothing. Blur chains two downscale and upscale passes with high-quality interpolation, producing a strong, blockless blur. The result is exported at full resolution in the original format at quality 0.92. Accepts images up to 40 MB, HEIC included.

Frequently asked questions

How do I pixelate a face in a photo?

Choose “Pixelate”, raise the strength and paint over the face with the brush. Download the image once it is well covered.

How do I hide a license plate or a detail in a screenshot?

Select the “Rectangle” tool and drag over the text. For sensitive data use a high strength.

Is it better to pixelate or blur?

Both hide well at high strength. Pixelation gives the classic blocky effect and blur looks smoother and more polished.

Can I undo a stroke?

Yes. “Undo” removes the last stroke and “Clear all” returns to the original image.
