Stop Blurring Your Sensitive Information in Screenshots

Want to hide parts of a screenshot that contain personal info, such as  💳 number? That’s a good idea, but you should stop using tools that pixelate, blur, or use other effects like swirls to hide this info—it’s almost like baiting strangers into trying to see what’s been redacted.

Unredacter can easily reveal text hidden using crude effects such as pixelation. It’s a free tool available for anyone to use, and it’s been created to generate awareness about the dangers of sharing poorly hidden text in screenshots.

The next time you want to share a screenshot online, use better tools to hide your personal data. The safest tool for most people is solid color blocks. You can quickly draw a solid color rectangle over sensitive information to make it almost impossible to decipher. On Windows and Mac, any free image editor can do it.
