Redact a PDF: black out text and images for good

Hide names, account numbers and anything else in a PDF so it can't be recovered. Draw boxes or let Find text mark emails, phone and card numbers and dates — the content under each box is removed, not just covered.

Quick answer

How do I permanently redact text in a PDF?

In Mergevanta's Redact PDF tool, draw boxes over what you want gone or use Find text to mark words, emails, phone and card numbers, then press Redact PDF. The text, image pixels and drawings under each box are deleted from the file, not just covered, so they can't be copied or uncovered.

FAQ

Redact PDF questions

It's gone. The characters, image pixels and drawings under each box are deleted and the old content is purged from the file, so searching or copying the redacted area finds nothing.

Files up to 4 MB are redacted on Mergevanta's server — encrypted end to end, processed in memory and never stored. Larger files are redacted in your browser and never leave your device.

Above 4 MB, each page with a box is redrawn in your browser as an image with the boxes painted in, so nothing under them survives. Those pages lose their selectable text; pages without boxes stay exactly as they were.

Yes. Find text spots emails, phone numbers, card numbers, dates, web links, Indian PAN and Aadhaar numbers and US Social Security numbers, plus any words you type. Check the matches, as unusual formats can be missed.

Draw boxes over a scanned page and the image pixels under them are removed. Find text only searches real text, so run OCR PDF first if you want to search a scan.

It also deletes the document's title, author and other metadata, attached files and scripts. Comments, links and form fields that sit under a box are always removed.

Not in the redacted file — that's the point. Keep your original somewhere safe if you might need the full version.
