Redact a PDF — Free, In Your Browser, No Adobe Pro
Permanently black out sensitive text, names, account numbers, signatures, and images. True content-stream redaction — not just a black rectangle on top.
Drop a PDF — the editor opens with the redaction tool active. Drag a rectangle over anything you want gone (text, images, signatures), and the redacted content is permanently removed from the file. Visual black box plus underlying content-stream scrub: search engines, OCR tools, and text-extraction utilities all return nothing where the redaction sits. The same engine the PDF Edit editor ships, running 100% in your browser. No upload, no signup, no Adobe Pro $19.99/month paywall.
Why local-only matters more for redaction than anything else
Redaction is the one PDF operation where the content you're working on is, by definition, the most sensitive content in the document — legal privilege, PII, trade secrets, healthcare records. Yet every other free online redaction tool — Smallpdf, iLovePDF, PDF24, Adobe's web version — has you upload that exact content to their servers before they let you redact it.
That's structurally insane. The whole point of redaction is that the sensitive content shouldn't leave your control. We run the redaction in your browser tab. There is no server-side copy of your PDF — pre-redaction or post-redaction.

How to Redact a PDF — Step by Step
-
Drop your PDF
Drag any PDF onto the dropzone above, or click Select PDF to browse. The file loads into your browser memory only — no server upload at any point.
-
Confirm the permanence warning
A one-time modal warns that redaction is permanent — the same warning Adobe Acrobat Pro shows. Click Continue to enter redact mode. (You only see this once per session.)
-
Drag rectangles over sensitive content
Drag a black rectangle over any text, name, number, signature, or image you want gone. Each rectangle deletes the underlying content from the PDF's content stream — not just covers it visually.
-
Save the redacted PDF
Click Save to download. The redacted content is permanently gone from the saved file — anyone who opens it in Acrobat, Preview, or any text-extraction tool gets nothing back where the redaction sits. This is permanent: keep an unredacted copy of the original if you might need it later.
True Redaction vs Drawing a Black Rectangle
The single most important thing about PDF redaction: visually covering text is not redaction. If you use a markup tool, image overlay, or basic "cover" feature to put a black rectangle on top of text, the underlying text is still in the PDF file. Anyone can:
- Click and drag to select the "redacted" text — it's still there as text
- Copy and paste the selection — full content recovered
- Open the PDF in any text editor → text is in plain XML / content streams
- Run OCR on a screenshot of the page to recover the visible portion
This is the famous redaction-fail problem that has burned governments, law firms, and Fortune 500 companies. The 2019 Manafort court filing where US prosecutors "redacted" a document and journalists copy-pasted to reveal the contents within minutes is the textbook case.
Real redaction (what we do, what Adobe Acrobat Pro does, what court rules require) has two layers: visual black box covering the content, AND content-stream scrub that actually deletes the text from the PDF's underlying data. Visually identical, but the text data is genuinely gone.
Redact PDF vs Adobe Acrobat Pro, Smallpdf, iLovePDF, PDF24
| Feature | PDF Edit | Adobe Acrobat Pro | Smallpdf | iLovePDF | PDF24 |
|---|---|---|---|---|---|
| PDF uploaded to a server? | No — 100% local | Yes (web) / No (desktop) | Yes | Yes | Yes |
| Cost | Free forever | $19.99/month | Free + paid | Free + paid | Free + paid |
| Account required? | Never | Yes | Free tier limited | Free tier limited | Free tier limited |
| True content-stream redaction (text actually deleted)? | Yes | Yes | Varies by tier | Varies by tier | Varies |
| Permanence warning? | Yes (one-time confirmation) | Yes | Limited | Limited | No |
| Daily limit? | None | None (paid) | 2 tasks/hour free | Free tier capped | Tier-based |
| Watermark on output? | No | No | Free tier: some | Some tools | No |
| Works offline after load? | Yes | Desktop yes / web no | No | No | No |
For a one-off redaction on a sensitive document, the calculus is brutal: pay Adobe $20/month for proper redaction with the desktop app, or use one of the free web tools that uploads your sensitive content to their server. Or use this — free, local, with the same content-stream scrub Adobe ships.
Who Redacts PDFs?
Lawyers + paralegals
Court filings, discovery production, FOIA / public-records responses. Court rules in most US jurisdictions require true redaction (content-stream scrub) for any document filed publicly that contains privileged or PII content.
HR + recruiting
Sharing an applicant's resume internally with reviewers, but redacting their name + contact info to keep the screen unbiased. Or redacting compensation data from offer letters before sharing.
Healthcare admin
HIPAA-covered records shared for research, second opinions, or insurance — patient identifiers redacted before sharing.
Compliance + audit
Financial documents shared with auditors, regulators, or external counsel — account numbers, customer names, and trade-secret figures redacted to scope.
Government + public records
FOIA / public-records-act responses where parts of a document are withheld under exemption — true redaction is the legal standard for what gets released.
Anyone sharing a sensitive PDF
Bank statements with account numbers, IDs with addresses, signed contracts where you only want to share the key terms — redact what shouldn't travel.
What Does Redact Mean in PDF?
In the PDF context, "redact" means permanently removing or blacking out content from a PDF page, in a way that the removed content cannot be recovered from the saved file. The word comes from editorial usage — "to redact" originally meant to edit a document for publication, including censoring sensitive parts. In digital PDFs, proper redaction has a specific technical meaning: both the visible content (covered with an opaque black rectangle) AND the underlying content-stream data (the actual text bytes in the PDF file) are removed.
Common things to redact:
- Personal identifiers — names, addresses, social security numbers, phone numbers, email addresses
- Financial details — account numbers, credit card numbers, bank routing numbers, salary figures, transaction amounts
- Legal privilege — attorney-client privileged communications, work product, settlement amounts
- Trade secrets — proprietary formulas, customer lists, supplier names, pricing data
- Healthcare — patient names, diagnoses, treatment dates, prescriptions (HIPAA-covered)
- Signatures + photos — anywhere a signature, ID photo, or other visual identifier appears

What does redact a PDF mean?
Permanently removing or blacking out sensitive content from a PDF in a way that the removed content cannot be recovered. Real redaction = visual black box + content-stream scrub. Just covering text with a rectangle is NOT redaction.
How do I redact text in a PDF?
Drag a rectangle over the text. The text is deleted from the PDF's content stream — not searchable, not selectable, not extractable.
How do I redact information on a PDF?
Same answer — drag rectangles over the information you want gone (names, account numbers, signatures, anything).
Is the redaction permanent?
Yes. The redacted content is permanently removed from the PDF's content stream. Search engines, OCR tools, and text-extraction utilities all return nothing for the redacted region.
What's the difference between redaction and a black rectangle?
A black rectangle on top only hides text visually — anyone can copy-paste to recover the underlying text. Real redaction (what we do) deletes the underlying text from the file. Visually identical, but the data is actually gone.
Can I redact images and signatures?
Yes. The black rectangle covers anything in its bounds — text, images, signatures, scanned content.
Can I undo a redaction?
Inside the editor session, yes (Ctrl+Z). After Save and download, the redaction is permanent.
Is my PDF uploaded?
No. The redaction runs entirely in your browser. This matters more for redaction than for any other PDF operation — Smallpdf, iLovePDF, PDF24, and Adobe's web version all upload. We don't.
Is redacting a PDF legal?
Yes — redaction is the standard practice for sharing legal documents while protecting privileged content. US courts, GDPR, and HIPAA all require redaction for certain content. The legal question is whether the redaction was done properly — which is why content-stream scrub matters.
Is there a file-size limit?
No artificial limit.
Does it work on mobile?
Yes, but redaction is much more accurate with a mouse than a finger. Use a desktop for high-stakes redaction.
Does it work offline?
Yes once the page has loaded.
What is the best free PDF redaction tool?
For privacy-first redaction with no upload, no Adobe Pro paywall, and true content-stream scrub, we believe pdfedit.com is the best. For desktop / batch automation Adobe Acrobat Pro is the gold standard but costs $19.99/month.
