Is redaction truly permanent?

Yes. The tool permanently removes the selected text and images from the PDF structure. The content cannot be recovered by copying, searching, or extracting text from the file.

How is this different from drawing a black box?

Drawing a black shape in an image editor or annotation tool only covers content visually — the text is still in the PDF and can be selected, copied, or found via Ctrl+F. Redaction removes the underlying data entirely.

Can I redact images as well as text?

Yes. The manual selection tool lets you draw redaction boxes over images, photos, or any visual area on the page.

Does redaction affect the rest of the document?

Only the marked areas are affected. All surrounding text, images, and formatting remain exactly as they were.

Can I undo a redaction?

Not after downloading the file. Redaction is permanent. Always keep a backup of the original PDF before redacting.

Does it work with scanned PDFs?

Yes. For scanned PDFs, you can manually draw redaction boxes over any area. Text search redaction only works on PDFs with selectable text layers.

Is there a limit to how many areas I can redact?

No. You can mark and redact as many areas as needed across all pages.
