PhotoFiltre7 - www.photofiltre.com
I usually do my basic photo editing in PhotoFiltre7. Every now and then, I need to blur sensitive data. Originally, I used the smudge tool, looks like a pointing finger in the toolbar, until I realized that PhotoFiltre has a built in blur option.
For this example I took a screenshot of DavesComputerTips.com and just going to demonstrate the blurring tool. So open your picture in PhotoFiltre and click on the pointing tool in the toolbar on the right-hand side.
Click and drag around the section you want blurred. You'll notice a dotted border forming. Everything inside this border will be blurred. I just dragged it around the first few words in my screenshot.
Then click on the Filter option in the top menu. Then click on Soften. Then you have two options, Blur and Blur more. If your blurring text the Blur one isn't sufficient. I click on the Blur more. This opens a little box that gives you more control over the blurring process.
Adjust the slider to your taste. Click on Direct preview to see how it's going to look before being applied. I just left it on 9 pixels and then click on OK. I used the smudge tool before, but the blur option gives a cleaner look.
