Can the blacked-out information be recovered?

No. The pixels are permanently overwritten with a solid color. Unlike blur, which can sometimes be reversed with image analysis, a blackout is irreversible.

Is blackout safer than blur?

Yes. Blur-based redaction can potentially be reversed using image processing techniques. A solid blackout replaces pixels entirely, making recovery impossible.

Can I redact multiple areas?

Yes. Draw as many rectangles as needed. Use the Undo button to remove the last redaction if you make a mistake.

Can I change the blackout color?

The default is black, but you can also choose white or a mosaic pattern for different use cases.

Is my image sent to a server?

No. All processing happens entirely in your browser. Your image and its contents never leave your device.

Image Redaction Tips & Use Cases

Privacy Protection — Before Sharing Documents

Always redact personal identifiers (ID numbers, account numbers, home addresses) from scanned documents or screenshot images before sharing them via email or messaging apps.

Social Media — Remove Background Information

Photos sometimes accidentally capture sensitive information in the background — documents, whiteboards, license plates. Redact this content before posting. Even small text is readable when digitally zoomed.

Business — Mask Confidential Figures

Share contracts, quotes, or internal reports externally with sensitive numbers and names blacked out. This lets you provide useful reference material while protecting confidential details.
