About Privacy Screenshot Redactor
Mask only the areas you choose
Upload or paste a screenshot, drag boxes over sensitive regions, then adjust each region with blur, pixelation, or a solid color. Undo, redo, resize handles, and the region list make it easier to refine the mask before exporting.
Local output with optional text detection
Text detection can suggest boxes for recognized words, but you stay in control of what is kept or removed. The edited image is rendered in the browser and can be copied or downloaded as PNG, JPEG, or WebP.
FAQ
Common questions and answers about this topic.
Are my screenshots uploaded to a server?
No. The screenshot you upload or paste, the boxes you draw, the OCR text detection, and the exported image are all processed entirely in your browser. Nothing is sent to or stored on any server, so even highly sensitive screenshots never leave your device.
Blur, pixelate, or solid color — which one truly removes the data?
A solid color cover at 100% opacity is the only option that truly removes the content underneath — those pixels are painted over and cannot be recovered from the exported image. Pixelation is medium protection (harder to reverse, but not guaranteed for predictable content such as text). Blur is the weakest, because a degraded version of the original still survives. For passwords, ID numbers, or anything that must never leak, use a solid cover at full opacity.
Why can blurred or pixelated content sometimes be recovered?
Blur and pixelation do not delete the original pixels — they transform them mathematically, so a degraded copy of the underlying signal remains in the exported image. Light blur, small pixel sizes, or predictable content (such as digits in a fixed font) can be partially reconstructed with deblurring or depixelation techniques. Increasing the blur radius or pixel size lowers the risk, but for truly irreversible redaction switch to a solid color cover.
How do I redact several sensitive areas at once?
Drag as many boxes as you need — each region is independent, so you can give one a solid cover and another a blur. The redaction list shows every box for quick selection or deletion, and undo/redo help you refine placement. To handle a lot of text at once, enable the experimental auto-detect, and OCR proposes boxes around recognized words that you can keep, adjust, or delete before exporting.
