Share second.
Select a region and reduce its visible detail with the free Blur tool. Keep secrets outside the capture, and check the exported image before sharing.
Region blur · Editable annotations · Free for Windows
Maxisnap’s Blur tool reduces detail inside a rectangle you draw over a screenshot. It includes earlier annotations in that region, which helps when cleaning up a capture for a ticket, tutorial, or chat. Blur is visual obscuring, not a guarantee that sensitive text cannot be inferred. For passwords, API keys, or other secrets, capture a smaller area, crop the secret out, or use a fully opaque redaction tool before exporting.
Security researchers have demonstrated recovery of pixelated text in Bishop Fox’s Unredacter research. A flattened image and a hidden secret are different things: always inspect the actual file you intend to share.
Check the whole screenshot
Check customer and teammate email addresses. Leave out addresses the recipient does not need, especially in a public ticket or tutorial.
Look for credentials in terminals, settings panels, and authorization headers. Keep them outside the image you share; blur alone is insufficient. Revoke or rotate any credential already exposed.
Review account numbers, order references, and customer identifiers. Remove information that is unrelated to the issue you are explaining.
Check browser address bars, private dashboard links, and query strings. A URL can contain a customer identifier or an access token.
Keep times that help explain the bug. Remove them when they expose a private session or activity that is irrelevant to the recipient.
Check names, avatars, messages, and channel titles around the area you captured. Crop unrelated conversations out before posting publicly.

- 01
Capture the screenshot
Press Ctrl+Alt+5 for a region or Ctrl+Alt+6 for the full screen. Choose a capture area that excludes passwords, API keys, and other secrets where possible.
- 02
Select the Blur tool
Click Blur in the editor toolbar, or press B with the default shortcuts. The current Windows app has one blur effect; it does not offer a blur-type selector or intensity slider.
- 03
Drag across the region
Drag a rectangle over the detail you want to obscure. Repeat for other regions. Earlier annotations in the selected area are included in the effect, and the blur remains editable in the editor.
- 04
Export and inspect
Use Save or Ctrl+S to export a file, then open that file and inspect the result before sharing. Use the editor’s Upload button when ready. Ctrl+Alt+7 starts a new region capture and upload; it does not upload this edited image.
Blur screenshot FAQ
How do I blur text on a screenshot?
Capture with Ctrl+Alt+5, select Blur or press B, and drag over the text. Save the edited screenshot and inspect the exported file. Blur reduces visible detail; for passwords or tokens, exclude the secret from the capture or crop it out.
Can blurred or pixelated text be recovered?
Sometimes. The result may still reveal enough structure to infer the original text. Saving the effect into an image does not guarantee secrecy. Remove sensitive content from the shared image rather than relying on blur alone.
Does Maxisnap blur cover earlier annotations?
Yes. The effect includes the screenshot and annotations drawn before that blur region. Those objects remain editable in the editor, so moving or deleting them can change the result. Inspect the final exported image before sending it.
Can I change the blur type or intensity?
Maxisnap 2.5.2 has a single Blur tool with a fixed effect. You can change the selected region, but there is no Gaussian-versus-pixelation selector or strength slider.
How should I remove a password or API key?
Capture a smaller region or use Crop to leave the secret outside the exported image. If cropping is unsuitable, use an editor with a fully opaque redaction tool and export a flattened copy. Maxisnap’s current filled shapes are translucent, so they are not a substitute for an opaque redaction block.
