FAQs

1. Can blurred or pixelated redactions be reversed?

Yes, weak blurring or pixelation can sometimes be undone using AI tools or image enhancement software. For secure redaction, use solid black boxes or permanent removal methods.

2. Why should metadata be removed when redacting an image?

Even after redacting visible content, metadata can still contain sensitive details like GPS location, author information, and timestamps, hence its important to clean meta data.
