I recently received an email from a gPost reader asking how we blur text in our screenshots (example: Gmail multiple inbox tutorial.) The majority of the screenshots on groovyPost are taken with an application called Snagit, available for both Windows and Mac. Snagit is one of my favorite tools because of its flexibility and feature set. You can do almost anything with it, yet it’s still super simple to use. The only downside, it’s not free. That said, I believe you get what you pay for and in this case, I have no issue dropping a few bucks to buy an amazing tool.
Why use blur?
Put simply, blurring out text is better than the alternative – redaction. Blur also doesn’t draw attention away from the important part of a screenshot. Take a look at the two examples below. On the left, we redacted the text to mask sensitive data; on the right, I used a blur filter. Since we’re probably not running an intelligence agency, blacking out sections of a screenshot with a big black box just doesn’t look attractive. The same can be said for YouTube videos, but adding blur to videos requires an entirely different program.
Let’s add blur!
To start out, you need to have a screenshot that has text you want to blur out. Maybe it’s personal information you don’t want to share with the world. As an example, I’ve pulled an Amazon order confirmation we’re going to block out the address from.
The below screenshot is small on purpose because it’s just an example of a possible screenshot choice, it’s not important.
Now that we have a screenshot to work with, from the Tools tab, you can decide if you want to blur using the Smooth filter or the Pixelate feature. Both work equally well, it just depends on the look you’re after. Keeping things simple, I’m going to click the down arrow and use a smooth filter with 25% intensity.
Now draw a box around the area of the screenshot that you want to blur out.
The default for both Smooth and Pixelate Blur is 25%. You can play with the intensity level by clicking on the region you selected and hitting the down arrow on the toolbar as shown above. The default setting is normally enough to render the text unreadable but still discernable that it was at one point text. See below for examples of the various levels of blur intensity.
To compare blur levels I compiled this shot below. As you know, even 10% is almost enough to render the blur unreadable. However, if you want to make sure people don’t decipher any sensitive data, you’ll need to apply at least 20%. Anything over 50% is obviously overkill.
Below is the end product of the screenshot after I’ve applied a blur to hide the shipping address and cropped out the sides. How does it look?
That covers adding blur to screenshots in Snagit. If you decide to buy a copy, please use this link to buy a copy of Snagit. Although the price will be the same for you, I will get a few bucks for the referral. Think of it as a tip for all this amazing information you just got for free. 😉
