Accepted files are PNG, JPEG and WebP, within the 20 MB limit.

Frequently asked questions

How do I calculate coordinates in percentages?

Locate the area relative to the total width and height. For example, an area starting at one quarter of the width corresponds to 25 percent for x. Do the same for y, width and height.

Is pixelation better than blur?

Pixelation is described as irreversible and works well to make text unreadable. Blur may be enough to soften a face or background, but it can sometimes be reversed with specialized tools.

Can I mask several areas in the same image?

Yes, the field expects one area per line with four values. Add as many lines as needed, then check each area in the result before downloading the final image.
