Blur Sensitive Information in a Screenshot Before You Share It

Screenshots leak more than people mean them to: an email address in the header, a name in a sidebar, a balance in the corner.

Screenshots are the most casually shared images there are, and they routinely carry more than the thing being pointed at: the account email in a corner, a customer's name in a list, a notification that slid in at the top, an order number, a balance. Most of it is invisible to the person sharing because they have stopped noticing their own interface.

Look at the edges first

The subject of the screenshot is almost never the problem. The problem is the browser tab titles, the sidebar, the account menu, the notification banner and the taskbar. Scan the border of the image before you scan the middle.

How to censor it

Drop the screenshot into the tool and drag a box over each thing that should not be public. Every box is applied at full resolution, so what you see is what downloads. Use as many boxes as you need, adjust the strength, then download the PNG.

Use pixelate at a large block size for text

Text is the easiest thing to recover from a weak censor. A gentle blur on a short string — a six-digit code, a short name — can sometimes be worked back by someone determined. Pixelation with a large block size removes far more information. When it matters, crank it until the shape of the text is gone entirely, not just soft.

The strongest option is cropping

If the sensitive part is at the edge, crop it off rather than obscuring it. Removed pixels cannot be recovered by anyone, which is a stronger guarantee than any amount of blur. Use the cropper for that, then blur whatever is left in the middle.
