BlurSnap

BlurSnap is a Windows screenshot utility built around an inverted workflow: instead of capturing a screen and then hunting for sensitive details to hide, the capture opens fully blurred and you paint to reveal only the parts you actually want to show. Anything you don't reveal stays hidden.

Paint to reveal — Press a global hotkey, select an area, and the editor opens with everything obscured. A brush uncovers the regions that matter; brush size, blur strength, hotkey and save folder are all configurable.

Hold to peek — Hold a key to see the original underneath, so you can find what you're looking for without guessing, then it blurs back. While peeking the editor is view-only, so nothing gets saved by accident.

Frosted glass mode (optional) — Goes a step further and replaces hidden regions with a plain sheet instead of a blur — useful when a screenshot is headed to a wider or less familiar audience.

Nothing to peel off — The hiding is applied to the pixels of the exported file rather than drawn as a separate layer, so there is no overlay to remove from the saved image.

Works entirely offline — BlurSnap makes no network calls at all: no cloud processing, no uploads, no accounts, no telemetry.

Finish in one step — When you're done, the result is copied to the clipboard and saved automatically.
