Practical Example & Use Case
Common Real-World Scenario
Blacking out bank account numbers and home addresses on bank statements before submitting them as proof of income for rental applications.
Technical Notes & Limitations
Browser Engine Architecture
Draws solid opaque black vector rectangles over target coordinate areas using `pdf-lib` so the underlying text cannot be selected or copied.
Frequently Asked Questions
Can someone un-redact the PDF to read the text?
No. The redaction burns permanent vector rectangles directly onto the content stream, making underlying content inaccessible.
