Before we dive into the how-to, let's discuss the importance of blurring text in screenshots.

Regardless of the method you choose, there are some best practices to keep in mind when blurring text in screenshots:
  1. Ensure Complete Obscurity: Make sure the blurred area completely covers the sensitive text, leaving no discernible characters.
  1. Use a Contrasting Color: When manually blurring text, use a color that contrasts with the background to ensure the blurred area is clearly distinguishable.

By following these best practices and using the right tools for the job, you can ensure that your screenshots maintain privacy and confidentiality while still conveying the necessary information.
