🧽 Screenshot Cleaner
Clean one screenshot locally by manually obscuring or cropping visible regions, then export a new flattened JPG or PNG copy.
Drop a screenshot here, or click to choose a file
One JPG, PNG, or WebP only. This browser-only version supports files up to 25MB.
All processing stays local in your browser by default. Nothing is uploaded.
Waiting for screenshot
After you upload a screenshot, tighten the crop if needed, add manual masks or screenshot strips, then export a new flattened JPG or PNG copy.
Screenshot Workspace
Start with the crop bar or corner handles, then add masks or strip presets only where needed.
Mask Style
Output Format
PNG keeps the pixel output as-is. JPEG automatically flattens onto white. Changing the output format makes the old result stale.
Changing this only affects the download filename. It does not re-export or change the current workspace.
Export Result
After you tighten the crop or add at least one mask and export, the preview for the current workspace will appear here.
The export only changes the visible regions you cropped or masked manually. It does not mean metadata was removed or that the file is suitable for formal sharing or formal submission.
Current Scope
This version handles one JPG, PNG, or WebP screenshot at a time. You can add manual rectangular masks, drop in quick top/bottom/row strips, optionally apply one final crop, and export a new flattened JPG or PNG copy locally in your browser.
It is not a formal redaction or sanitize tool. It does not decide what should be hidden, and it does not promise safe sharing, anonymization, or formal-submission readiness.

Hard Disclaimer
All processing stays local in your browser by default with no uploads. But this tool only changes the visible regions you crop or mask manually. It does not check whether you missed other sensitive details.
`Solid cover`, `pixelate`, and `blur` are only visual effects. Visual effects are not the same as secure redaction, guaranteed anonymization, or safe-to-share claims.
