How to Redact PDF vs Adobe Acrobat (Free vs Paid)

What real redaction means

Real redaction permanently removes the sensitive content from a PDF. The output is flattened: there is no hidden text layer underneath the black boxes, nothing to select, copy, or reveal by editing the file. When someone opens the redacted PDF, the removed words are simply gone.

That is very different from covering text with black highlighting, black rectangles in a word processor, or drawing shapes over a PDF in a viewer. Those tricks only change what the text looks like. The words are still stored in the file, and anyone with basic PDF software can select the "hidden" text, copy it, delete the covering shape, or extract it. There have been well-known public cases where documents "redacted" this way leaked the exact information they were supposed to protect.

So the test is simple: after redacting, try to select the text under a black box, search the document for a redacted word, and copy-paste from that area. If anything comes back, it was not real redaction. Both BGone's Redact PDF tool and Adobe Acrobat's redaction feature pass this test — they produce flattened output with no recoverable text layer.

Side-by-side comparison

How to redact a PDF with BGone (free)

1. Open the tool. Go to BGone's Redact PDF tool. Nothing to install, no account to create.
2. Upload your PDF. Choose the file from your device. Because processing happens entirely in your browser, your file never leaves your device.
3. Mark what to remove. Draw boxes over every name, number, address, or paragraph that must go. Work page by page, and do not rely on highlighting — draw a full redaction box over each item.
4. Check for hidden copies. Search the document for each sensitive term before you redact. If a name appears in a header, footer, or appendix, it needs its own redaction box. Also check metadata-style fields like author names if the document carries them.
5. Apply the redaction and download. Apply, then download the flattened PDF. Open the downloaded file and try to select or search for a redacted word — you should find nothing.
6. Keep your original safe. Redaction is permanent. Store the unredacted original somewhere secure and separate before you share the redacted copy.

How to redact a PDF with Adobe Acrobat

1. Open your PDF in Acrobat. Use Acrobat Pro (or the current Acrobat plan that includes redaction), and open the document you need to clean.
2. Find the Redact tool. Open the Tools view and choose Redact. Acrobat offers two modes: mark areas by hand, or search-and-redact by text pattern, such as phone numbers or email addresses.
3. Mark or search for sensitive content. Draw boxes over items by hand, or run a pattern search and review every match before confirming. Pattern search is fast, but always review the matches — it can catch things you meant to keep or miss unusual formats.
4. Apply the redaction. Apply the redactions. Acrobat removes the underlying text and flattens the result, just like BGone.
5. Sanitize and save. Acrobat can also strip hidden information such as metadata, comments, and hidden layers. Use that step if your document contains them, then save a new copy.
6. Verify before sharing. Reopen the saved file and search for a redacted term. Confirm that nothing is selectable or searchable under the black boxes.

Acrobat's advantage is scale: pattern search, batch processing across many files, and audit-friendly workflows for teams. For a single document, the result is the same as BGone's free tool — a flattened PDF with the sensitive text permanently gone.

When Acrobat makes sense

• Enterprise and compliance teams. If your organization needs audit logs, role-based access, centralized licensing, or a documented redaction workflow, Acrobat fits into that structure. A free browser tool is not designed to be an enterprise system.
• Batch workflows. Redacting the same pattern across hundreds of pages or dozens of files is where Acrobat's search-and-redact and batch features pay for themselves.
• Combined PDF work. If you already use Acrobat daily for editing, forms, e-signatures, and document comparison, redaction is one more feature inside a tool you already pay for.

For everyone else — a freelancer cleaning up one contract, a landlord sharing a lease, a student filing an application, a small business handling HR paperwork — the free tool does the same core job without a subscription.

Before you share: a quick checklist

• Search the redacted file for every sensitive term. Zero matches is the goal.
• Try to select text under each black box. Nothing should be selectable.
• Check every page, including headers, footers, appendices, and scanned-image pages.
• Check the file name. A filename like "John-Smith-medical-record.pdf" can leak what the redaction hid.
• Keep the original separate. Once you share the redacted copy, you cannot undo it — and you should not want to.

For a deeper walkthrough of the BGone tool itself, see our guide on how to redact a PDF. If the document you are cleaning started as a scanned file or needs text edits first, you can also convert the PDF to Word — but remember that editing in Word is not redaction, and the final redaction should still happen in a tool that flattens the output.
