What coordinate system does the tool use?

The tool uses PDF points with the origin (0,0) located at the bottom-left corner of the page.

Can I redact multiple areas at once?

Yes, you can provide a list of multiple rectangles in either JSON or CSV format to redact several fields in one operation.

Is the redaction permanent?

Yes, the tool renders a new PDF with opaque black boxes placed over the specified coordinates, effectively masking the underlying content.

What is the purpose of the 'Show Redaction Label' option?

It allows you to display a text label (e.g., 'NAME' or 'ID') inside the black redaction box to help identify what information was removed.

Are there limits on file size?

The tool supports PDF files up to 300MB.
