To redact a PDF online, upload it to Redact PDF AI, choose which kinds of personal data to remove (names, emails, phone numbers, addresses, IBANs, card numbers), review the redactions the AI proposes, and download the result. The output is flattened, so the redacted text is deleted from the file rather than hidden under a black box.

How to redact a PDF online in 4 steps

  1. 1

    Upload your PDF

    Drop a PDF, JPG or PNG into the box above. Scanned documents are fine: built-in OCR reads the text first. Files travel over TLS and are processed on EU and Swiss-hosted Azure infrastructure.

  2. 2

    Pick what to redact

    Tick the categories that matter for this document — people, emails, phone numbers, addresses, organizations, dates, IBANs, credit cards — and add any words that must always (or never) be redacted.

  3. 3

    Review the AI’s redactions

    The AI marks every match on every page. Open the Studio editor to remove a false positive, keep a term, or draw a box over something it missed.

  4. 4

    Download the redacted PDF

    Export a flattened copy. Try to select or search for the redacted text: there is nothing left to find, because the page was rasterized and the text layer removed.

Why a black box is not a redaction

Most "redacted" PDFs that leak were made by drawing a black rectangle over text in a PDF editor. The rectangle is an annotation; the text underneath is still in the file and can be selected, copied, searched, or extracted by any free tool. A real redaction deletes the content. Redact PDF AI rasterizes every page and drops the text layer and metadata, so the redacted output cannot be reversed. Before sending any redacted PDF, try to highlight the black areas: if you can select text, it was never redacted.

How to tell whether a redaction can be undone

What the AI redacts for you

You choose the categories per document. Anything the AI flags can be kept or removed in the editor before you export.

  • People’s names, including initials and signature blocks
  • Email addresses, including obfuscated ones
  • Phone numbers in local and international formats
  • Postal addresses
  • Organization and company names
  • Dates, including dates of birth
  • IBANs and bank account numbers
  • Credit and debit card numbers

Step-by-step guides per data type and document: names, email addresses, IBANs, card numbers, medical records, lease agreements and all redaction guides.

How it compares to other free online PDF redactors

Most free online redactors work like a highlighter: you find and mark every sensitive item yourself. That is fine for a one-page letter and unworkable for a 60-page bank statement or a scanned contract. The difference is who does the finding.

Frequently asked questions

Is it really free to redact a PDF here?

Yes. You can upload and redact your first document without creating an account. Signing up gives you free credits for more pages; paid plans start at US$50 a month for 1,000 pages when you redact regularly.

Is it safe to upload confidential documents to an online redactor?

Your file is encrypted in transit and at rest, processed on Microsoft Azure in Europe and Switzerland, deleted automatically (or immediately after download if you prefer), and never used to train AI models. The platform runs on infrastructure holding SOC 2 Type II and ISO 27001 certifications and is HIPAA-eligible.

Can a redaction made here be undone?

No. The output is rasterized and the original text layer is removed, so there is nothing to recover by copy-paste, search or PDF forensics. Only redactions made by drawing a shape over text can be undone, which is why we do not do that.

Does it work on scanned PDFs and photos of documents?

Yes. Built-in OCR reads the text inside scans, faxes and phone photos (JPG, PNG) in more than 100 languages before the AI looks for personal data, so a scanned contract is redacted as reliably as a digital one.

How do I redact a PDF without Adobe Acrobat?

Use a browser-based redactor like this one. Acrobat Pro’s Redact tool is reliable but needs a paid subscription and you must search for each item yourself; here the AI finds the personal data for you and the export is permanent.

Can I redact a PDF on a Mac or an iPhone?

Yes, it runs in any modern browser on macOS, iOS, Windows and Android. If you would rather use built-in tools, read our guides to redacting in Preview on a Mac and on an iPhone or iPad, including where those tools fall short.

Which file types can I redact?

PDF, JPG and PNG. Images are treated like scanned pages and come back as a redacted PDF.

Can I redact many PDFs at once?

Yes. Signed-in users can upload a whole batch and download the results as one archive, and developers can automate the same pipeline through the REST API.
