    I’ve heard blur is not destructive. Please use a paintbrush on 100% opacity if you do this

      When I post pictures with blurred information, I replace the info with something trollish and then blur it. Nobody appreciated that so far. :(

      Depends on the kind of blur. Some kinds can indeed be almost perfectly removed if you know the used blurring function, others are destructive. But, yes, don’t take that chance. Always delete/paint over sensitive information.

      Source: we had to do just that in a course I took a long time ago.

        I prefer sampling the surroundings, typing out a different number or text over it, then blurring with a non destructive effect.

        wouldn’t you also need to know in what kind of pattern the blur was applied. I am sure if you do it multiple times starting from multiple non identical partitioning of the region, it will be impossible.

        Always paint over sensitive information.

        Not in PDF tho. There, the stroke is saved in metadata…

        Actually not always, there is a script that can recover text from mosaic’d screenshots if the font and pixellation technique is known. I just use a fake mosaic – the easiest way is to paste a bitmap of non-confidential text from elsewhere in the screenshot and then apply the filter.
