Hide sensible information by adding a professional blur effect to your images, pictures or screenshots with the free and open-source tool Pinta.
Create a Screenshot
First you need a picture where you want to apply the blur effect. In this example I’ve chosen my Github profile settings page. It does not contain any sensible information, but for this demo we want to blur the Biographie section of the screenshot.
Select Area to blur
Next open the Image with Pinta and select the area you want to apply the blur effect.
Apply Blur Effect
Go to Effects > Blurs > Gaussian Blur and select a desired radius. For simple text fields I recommend a radius of 10, for pictures 50.
Review the Image
That’s all! The sensitive information is now blurred. Make sure to re-check the rest of the image and blur other relevant sections as well.
