A lawyer friend of mine once “redacted” a PDF by drawing black rectangles over the sensitive text in Preview, then saving it. The text was still there. You could select it, copy it, paste it into a text editor, and read every word. She sent this to opposing counsel.
This happens more often than you’d think. In 2023, Paul Manafort’s legal team made the same mistake in a federal court filing — their “redacted” text was fully readable by anyone who knew how to copy-paste. It made national news.
Real redaction permanently removes the underlying text data from the PDF. Drawing a box over it is cosmetic — the text is still embedded in the file. If you’re handling anything sensitive — legal documents, medical records, financial data, HR files — the distinction matters enormously.
Why Adobe Isn’t the Answer for Most People
Adobe Acrobat Pro has a proper redaction tool. It works well. It costs $22.99/month.
For a law firm or a compliance department, that’s fine. For a freelancer who needs to redact something twice a year, it’s absurd. You’re paying $276 annually for a feature you use for ten minutes.
And here’s what really bothers me: redaction should be a basic PDF feature, not a premium upsell. It’s a security tool. Gating it behind a $23/month subscription means most people just won’t do it properly.
Free and Low-Cost Options That Actually Work
Option 1: Google Drive + a Workspace Add-On
If your PDFs are already in Google Drive — and for most people working in Google Workspace, they are — the cleanest approach is editing them right there.
Super PDF Editor is a Workspace add-on that includes a redaction tool. You open the PDF in Drive, select the text or area you want to redact, and it permanently removes the content. No downloading, no separate app, no subscription required for basic use.
The key advantage: it works where your files already live. No “download → edit → re-upload” dance.
Option 2: LibreOffice Draw (Free, Desktop)
LibreOffice can open PDFs and let you delete or cover content. It’s free and open-source. The downside: it sometimes mangles complex PDF layouts, and you need to be careful that you’re actually removing text data and not just covering it visually.
Option 3: PDF-XChange Editor (Windows Only)
A solid desktop option for Windows users. The free version includes basic redaction. The interface is cluttered but functional. Not an option if you’re on Mac or Chrome OS.
How to Verify Your Redaction Actually Worked
Whatever tool you use, always verify:
- Open the “redacted” PDF in a different viewer
- Try to select text in the redacted area — if you can select it, the redaction failed
- Use
Ctrl+A(orCmd+A) to select all text, then paste into a text editor - Search for keywords from the redacted content
If any of those reveal the hidden text, your redaction is cosmetic, not real. Go back and use a tool that actually strips the text data from the file.
The Stakes Are Higher Than You Think
Bad redaction isn’t just embarrassing — it can be a legal liability. GDPR, HIPAA, and various state privacy laws require that personal data be properly removed when requested. A black box that doesn’t actually remove the data doesn’t meet that standard.
Take the extra sixty seconds to do it right. Your future self — and your clients — will thank you.
