Question 1

Is redacting a PDF the same as covering text with a black box?

Accepted Answer

No. Covering text with a black rectangle is not true redaction — the underlying text remains selectable and extractable. MyPDFBoy removes content from the PDF content stream, making it permanently unrecoverable.

Question 2

Does my PDF get uploaded to a server?

Accepted Answer

No. All processing happens entirely in your browser using your device's CPU and memory. Your PDF never leaves your machine.

Question 3

What file size limit does the redaction tool support?

Accepted Answer

The redaction tool supports PDF files up to 50MB.

Question 4

Can I redact multiple areas across different pages?

Accepted Answer

Yes. You can draw redaction zones on any combination of pages in a multi-page PDF. All zones are applied in a single processing step.

Question 5

Will redaction remove metadata like author name or creation date?

Accepted Answer

Yes. The redaction process also strips XMP metadata, bookmarks, and incremental save history that could otherwise reveal document history.

Question 6

Can I undo a redaction zone before applying?

Accepted Answer

Yes. You can undo and redo zone drawing actions with Cmd+Z / Cmd+Shift+Z before you click Apply. Once applied and downloaded, the redaction is permanent.
