What does redact a PDF mean?

Redacting a PDF means permanently removing or blacking out sensitive content — names, addresses, account numbers, social security numbers, signatures, or anything else that shouldn't be in the published version. Proper redaction has two parts: a visual black rectangle covering the content, AND a content-stream scrub that actually deletes the underlying text from the PDF. Without the second part, anyone can recover the redacted text by selecting it, copying, or running text extraction — the famous redaction-fail problem that's burned governments, law firms, and Fortune 500 companies repeatedly.

How do I redact a PDF?

Drop the PDF on pdfedit.com/redact-pdf. The editor opens with the redaction tool active. Drag a black rectangle over any text, image, or region you want gone. The redacted content is permanently removed — visual cover + content-stream scrub. Save the redacted PDF. No account, no upload, no Adobe Pro.

How do I redact a PDF for free?

Use this tool — 100% free, no signup, no daily quota, no Adobe Pro $19.99/month subscription. Drop the PDF, drag rectangles over the content to redact, save. The redaction runs entirely in your browser using pdf-lib.

How do I redact a PDF without Adobe Pro?

Use pdfedit.com/redact-pdf. Adobe Acrobat Pro charges $19.99/month for redaction; ours is free, runs in your browser, and provides the same content-stream scrub Adobe does (visual cover + underlying text deletion). The difference: Adobe also runs server-side in their web version (your PDF uploads to Adobe's servers); we run 100% locally.

How do I redact text in a PDF?

Drop the PDF here. After the one-time permanence warning, drag a rectangle over the specific text you want to remove. The text is deleted from the PDF's content stream — it's not searchable, not selectable, not extractable, not recoverable from the saved file.

How do I redact information on a PDF?

Same answer — drop the PDF, drag rectangles over the information you want gone (names, account numbers, signatures, photos, anything). The redaction deletes both the visual content and the underlying text data.

How do you redact in PDF?

Three steps: (1) drop the PDF on this page; (2) confirm the permanence warning; (3) drag rectangles over what you want gone. Save when done.

Is this PDF redaction tool free?

Yes. 100% free forever — no trial, no premium tier, no per-file charge, no daily quota. Adobe Acrobat Pro charges $19.99/month for the same feature.

No. The redaction runs entirely in your browser. This matters MORE for redaction than for any other PDF operation — the content you're redacting is by definition the most sensitive thing in the document (legal privilege, PII, trade secrets, healthcare data). Uploading a PDF to redact it on someone else's server is structurally backwards. Smallpdf, iLovePDF, PDF24, and Adobe's web version all upload. We don't.

Is the redaction permanent?

Yes. The redacted content is permanently removed from the PDF's content stream — not just covered with a black rectangle. Search engines, OCR tools, copy-paste, and text-extraction tools all return nothing for the redacted region. This is what Adobe calls 'true redaction' and what court rules require for legal filings.

What's the difference between redaction and a black rectangle on top?

Critical difference. A black rectangle on top of text (using a markup tool, image, or basic 'cover' tool) only hides the text visually. The underlying text is still in the PDF — anyone can select it, copy it, run text extraction, or use OCR on a screenshot to recover it. Real redaction (what we do, what Adobe does) deletes the underlying text from the content stream. Visually identical, but the data is actually gone. The Manafort court filing scandal in 2019 was a famous redaction-fail where a US prosecutor submitted a 'redacted' filing where the text was just covered, and journalists copy-pasted to reveal the contents within minutes.

Can I redact images and signatures, not just text?

Yes. The black rectangle covers anything in its bounds — text, images, signatures, scanned content, lines, shapes. The visual cover is opaque black, and any text under the rectangle is also content-stream deleted.

Can I undo a redaction?

Inside the editor session, yes — Ctrl+Z works on redact rectangles like any other element. After you Save and download, the redaction is permanent in the saved file. There's no recovery from a saved redacted PDF (which is the whole point — if redactions could be undone, they'd be useless).

Why is the confirmation modal there before I can redact?

Same reason Adobe shows one — redaction is permanent in the saved file. The one-time modal makes sure you're not redacting accidentally. After confirming once per session, you can drag as many redaction rectangles as you want without further prompts.

Is redacting a PDF legal?

Yes — redaction is the standard practice for filing legal documents publicly while protecting privileged or private information. US courts, the GDPR (EU), and HIPAA (US healthcare) all explicitly require redaction for certain content categories. The legal question isn't whether redaction is legal, it's whether the redaction was done properly — which is why content-stream scrub matters more than just a black rectangle.

Is there a file-size limit?

No artificial limit. Memory is the only ceiling.

Does it work on mobile?

Yes — iPhone Safari, iPad, Android Chrome — though redaction is much more accurate with a mouse than a finger. For high-stakes redaction (legal filings, medical records) use a desktop.

Does it work offline?

Yes once the page has loaded. The PDF Edit engine is cached in your browser.

What is the best free PDF redaction tool?

For privacy-first redaction with no upload, no Adobe Pro paywall, and true content-stream scrub (not just a visual black rectangle), we believe pdfedit.com is the best free option. For desktop-only batch automation, Adobe Acrobat Pro is the gold standard but costs $19.99/month and requires the desktop app. Most other free 'redaction' tools online either upload your file or only draw a black rectangle without scrubbing the underlying text — neither is acceptable for genuinely sensitive content.

Hoʻopau Maoli vs Kaha ʻana i Huinahā ʻEleʻele

The single most important thing about PDF redaction: ʻo ka uhi ʻana i ka kikokikona ʻAʻOLE ia he hoʻopau. 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:

Kaomi a huki e koho i ka kikokikona “i hoʻopau ʻia” — aia mau ia ma ke ʻano he kikokikona
Kope a pakomu i ke koho — ua hoʻihoʻi piha ʻia ka ʻike

E holo i ka OCR ma luna o kahi kiʻi paʻi o ka ʻaoʻao e hoʻihoʻi i ka ʻāpana ʻike ʻia

This is the famous hoʻopau-hāʻule 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.

He Aha Ke ʻAno o Redact ma ka PDF?

In the PDF context, "redact" means ka wehe mau ʻana a i ʻole ka hoʻopau ʻeleʻele i ka ʻike mai loko mai o kahi ʻaoʻao PDF, 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.
