Screenshot Privacy Scrubber
Draw exact redaction regions, flatten them into new pixels, and export a cleaned PNG with an optional manifest.
What This Tool Does
Screenshot Privacy Scrubber removes selected regions by painting opaque pixels into a newly encoded image. Unlike an annotation overlay, the exported PNG contains no recoverable text or image pixels beneath each black region.
How to Use
- Choose a screenshot and drag across every name, message, identifier, face, location, or account detail that should not be shared.
- Undo or clear inaccurate regions, then export the flattened PNG.
- Open the exported file and inspect it at full size before sending it.
How the Analysis Works
Pointer coordinates are mapped to source-image pixels, rectangles are filled on the raster canvas, and the complete canvas is encoded into a new PNG. The optional manifest contains rectangle coordinates but no OCR text.
Limits and Responsible Use
The tool does not automatically discover private information or inspect cropped-out browser data. Manual review can miss small details, reflections, filenames, tabs, notifications, or context that remains sensitive even after text is covered.
Examples
Share a support screenshot
A dashboard screenshot containing an email, account ID, and private note
Result: A flattened PNG with all three regions replaced by opaque pixels.
Frequently Asked Questions
Can someone remove the black rectangles?
Not from the flattened PNG: the underlying pixels are replaced. Keep the original file private.
Why not use blur?
Blur can preserve recognizable structure and may be partially reversible. Opaque replacement is the safer default.
