This guide will show you how to blur sensitive data within screenshots in text articles on Clueso. Blurring helps protect privacy and hide confidential information like email addresses, API keys, or personal data before publishing. Follow these steps to blur sensitive information in your screenshots:
1

Select the screenshot

Begin by selecting the screenshot that contains the sensitive information. Hover over it to reveal the editing toolbar — you’ll see a pen icon at the top-right corner of the image.Click the pen icon to open the screenshot editor.
2

Select the Blur tool

In the screenshot editor toolbar, you’ll see a row of annotation tools:
  • Select — move and resize shapes
  • Crop — crop the image
  • Rectangle — draw a rectangle overlay
  • Circle — draw a circle overlay
  • Arrow — draw an arrow annotation
  • Spotlight — highlight an area
  • Blur — blur a region
Click the Blur tool to activate it.
3

Draw the blur area

Click and drag across the specific area you want to blur. A blur rectangle will appear over the selected region, obscuring the content underneath.You can draw multiple blur regions on the same screenshot. After drawing, you can:
  • Resize the blur area by dragging its handles
  • Move it by clicking and dragging
  • Adjust the corner radius using the slider in the right panel
  • Delete it by selecting it and pressing Delete
4

Save your changes

When you’re satisfied with the blur, click Save edits at the bottom of the editor to apply the changes. Click Discard and exit if you want to cancel without saving.The blur is permanently applied to the image — readers will not be able to see the original content underneath.

Common Use Cases

Sensitive dataExample
Email addressesBlur user@company.com in settings screenshots
API keys and tokensBlur sk-abc123... in developer dashboard captures
Personal informationBlur names, phone numbers, or profile pictures
Financial dataBlur revenue figures, billing details, or pricing

Use the corner radius slider in the right panel to give your blur rectangles rounded corners for a more polished look.
If you need to highlight an area instead of blurring it, use the Spotlight tool — it dims everything except the selected region.
