How it works
Paste or drop a screenshot
Take a screenshot and press Ctrl+V right on this page — no need to save a file first. Nothing is uploaded.
Drag over the sensitive parts
Each rectangle is filled with solid black, pixelated, or blurred — your choice per area. Undo with Ctrl+Z.

The export is re-encoded from a clean canvas: covered pixels are destroyed, not hidden, and all metadata is dropped automatically.
Why screenshot redaction goes wrong
Two classic mistakes leak information from "redacted" images. The first is covering instead of destroying: drawing a black box in a PDF or layered image editor leaves the original text underneath, recoverable by anyone who removes the layer. The second is trusting blur: pixelated and blurred text can often be reconstructed, because short strings (card numbers, passwords) have few possible renderings to match against.
This tool avoids both: every redaction replaces the actual pixels on a flat canvas before export, and the default mode is solid black — the only style that's mathematically irreversible.
What people redact
A hidden bonus: metadata is stripped
A redacted screenshot that still carries EXIF data can leak where and when it was taken — and some formats embed a thumbnail of the unedited image. Because the export here is re-encoded from a clean canvas, none of that survives. To check any image's metadata, try our metadata remover.

Frequently asked questions
How do I redact a screenshot without uploading it?
Paste it on this page (Ctrl+V / Cmd+V) or drop the file, drag rectangles over the sensitive parts, and download. Everything runs in your browser — the image never reaches a server.
How do I black out text in a screenshot?
Load the screenshot (paste or drop it), keep Solid black selected, and drag a rectangle over the text. The pixels underneath are replaced with black before export — not covered by a layer someone could remove later.
Is blurring sensitive information safe?
Not always. Blurred and pixelated text can sometimes be reconstructed, especially short strings like passwords and account numbers. For anything truly sensitive, use solid black — it destroys the pixels completely and is the default here.
Can the redacted areas be removed to reveal the original?
No. Unlike PDF redaction mishaps where a black box covers intact text, this tool permanently replaces the pixels before export. The downloaded file contains no trace of the covered content.
Does the exported screenshot contain metadata?
No. The export is re-encoded from a clean canvas, which drops all EXIF metadata — location, device info, timestamps — and any embedded thumbnail of the original.
Can I redact several areas with different styles?
Yes. Pick a style, drag a rectangle, switch styles, drag the next one. Each area keeps its own style, and Undo removes the most recent.
