📚 Did You Know? The Importance of Proper Redaction

Redaction is the process of obscuring or removing sensitive information from a document before publication or sharing. In the digital age, this is crucial for protecting against identity theft. However, improper redaction can create a false sense of security. For example, simply drawing a semi-transparent black box over text in a PDF editor can sometimes allow the underlying text to be copied. This tool avoids that risk by creating a completely opaque, solid-color layer that is "flattened" into the final image, ensuring the covered data is truly and permanently hidden.
