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.

Whakangaromia he PDF — Kore Utu, I Tō Tirotiro, Kāore he Adobe Pro

Whakaponotia te tuhinga whakatapu, ngā ingoa, ngā tau pūkete, ngā hainatanga, me ngā whakaahua kia mangu pūmau. Whakangaromanga awa-ihirangi pono — ehara i te tapawhā mangu noa i runga.

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.

The same engine the PDF Edit editor ships, running 100% in your browser. No upload, no signup, no Adobe Pro $19.99/month paywall.

Ko te whakangaromanga te mahi PDF kotahi e mōhiotia ana ko ngā ihirangi e mahia ana e koe, mā te whakamāramatanga, ko ngā ihirangi tino whakatapu o te tuhinga — motika ture, PII, mea muna ā-pakihi, rekōta hauora. Heoi ko ētahi atu taputapu whakangaromanga ipurangi kore-utu — Smallpdf, iLovePDF, PDF24, te putanga paetukutuku o Adobe — ka tono kia tukuna ērā ihirangi tonu ki ā rātou tūmau i mua i te tukunga ki a koe ki te whakangaro.

That's structurally insane. Ko te tino tikanga o te whakangaromanga, kia kaua ngā ihirangi whakatapu e wehe atu i tō mana whakahaere. We run the redaction in your browser tab. There is no server-side copy of your PDF — pre-redaction or post-redaction.

Whakangaromanga Pono ki te Tuhi i tētahi Tapawhā Mangu

The single most important thing about PDF redaction: ko te taupoki kitea i te tuhinga ehara i te whakangaromanga. 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:

Pāwhiri me te tō ki te tīpako i te tuhinga “whakangaro” — kei reira tonu ia hei tuhinga
Kape me te whakapiri i te kōwhiringa — kua riro mai katoa te ihirangi
Huakina te PDF i tētahi ētita tuhinga → kei roto te tuhinga i te XML / awa-ihirangi mārama
Whakahaerehia te OCR i tētahi hopukanga mata o te whārangi hei whakahoki mai i te wāhanga e kitea ana

This is the famous rahuatanga whakangaromanga 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: pouaka mangu kitea e taupoki ana i te ihirangi, AND horoinga awa-ihirangi that actually deletes the text from the PDF's underlying data. Visually identical, but the text data is genuinely gone.

Ko Wai e Whakangaro PDF?

Roia + paralegal

Ngā tukunga kōti, ngā hua kōkiri, ngā whakautu FOIA / rekōta tūmatanui. Ko ngā ture kōti i te nuinga o ngā mana whakahaere o te US e tono ana i te whakangaromanga pono (horoinga awa-ihirangi) mō tētahi tuhinga e tukuna ana ki te marea kei roto ai he motika, he ihirangi PII rānei.

HR + tāmi mahi

Te tiri i te kōrerorero kiritaki i roto, engari te whakangaro i tōna ingoa + mōhiohio whakapā kia kore ai te mata e mōhiotia. Te whakangaro rānei i ngā raraunga kāmahi mai i ngā reta tukunga i mua i te tuarihanga.

Whakahaere hauora

Ngā rekōta e taupokina ana e HIPAA e tiriparahia ana mō ngā rangahau, ngā whakaaro tuarua, ngā inihua rānei — ka whakangaromia ngā tohutohu tūroro i mua i te tuarihanga.

Whakaritenga + arotake

Ngā tuhinga ahumoni e tiriparahia ana ki ngā kaiarotake, ngā kaiwhakarite, ngā kaitohutohu o waho — ngā tau pūkete, ngā ingoa kiritaki, me ngā tatauranga muna ā-pakihi e whakangaromia ana ki te whānuitanga.

Kāwanatanga + rekōta tūmatanui

Ngā whakautu FOIA / ture rekōta tūmatanui i te wā ka pupurihia ētahi wāhanga o tētahi tuhinga i raro i te wāhanga whakawātea — ko te whakangaromanga pono te paerewa ture mō te aha e tukuna ana.

Ko ngā tāngata e tiri ana i tētahi PDF whakatapu

Ngā tauākī pēke me ngā tau pūkete, ngā tuakiri me ngā wāhi noho, ngā kirimana hainatia kei te pīrangi koe ki te tiri i ngā kupu matua anake — whakangaromia ngā mea kia kore e haere.

He Aha te Tikanga o te Whakangaro i te PDF?

In the PDF context, "redact" means te tango pūmau, te muru rānei i ngā ihirangi mai i tētahi whārangi 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.

Ngā mea noa hei whakangaro:

Tohutohu whaiaro — ngā ingoa, wāhi noho, tau haumarutanga pāpori, tau waea, wāhitau īmēra
Taipitopito ahumoni — tau pūkete, tau kāri nama, tau aratohu pēke, tau utu, ngā moni mahi
Motika ture — ngā kōrero motika roia-kiritaki, hua mahi, ngā moni whakatau
Mea muna ā-pakihi — ngā tikanga rangatira, rārangi kiritaki, ingoa kaiwhakarato, raraunga utu
Hauora — ingoa tūroro, taukaea mate, rā maimoatanga, rongoā (e taupokina ana e HIPAA)
Hainatanga + whakaahua — ki hea atu tētahi hainatanga, whakaahua tuakiri, tohu kitea ranei e whakaaria ana

He aha te rerekētanga o te whakangaromanga me te tapawhā mangu?

Ko te tapawhā mangu i runga noa ka huna i te tuhinga ki te kanohi — ka taea e tētahi te kape-whakapiri kia whakahokia mai te tuhinga. Ko te whakangaromanga pono (tā mātou e mahia ana) ka muku i te tuhinga mai i te kōnae. He ōrite ki te kanohi, engari kua ngaro tūturu te raraunga.
