PDF Redact / Blackout

Lets you draw blackout rectangles over sensitive areas (SSN, account numbers, addresses)
Exports a flattened PDF (pages are re-rendered as images with the blackout applied)
Runs locally — your PDF isn’t uploaded

Because the output is flattened, text will not remain selectable/searchable.
If you need to keep selectable text, use a dedicated “text redaction” workflow (harder to do safely in-browser).
