Redact a PDF online, free

Upload a PDF and Re-Doc finds the personal data in it for you: names, ID and account numbers, addresses, phone numbers and emails. Scanned pages get permanent black boxes. Text-based PDFs get the real values swapped for realistic synthetic ones, so the file still reads normally. Your first 10 pages are free.

What Re-Doc changes

Orange boxes are what Re-Doc finds on its own. Text-based files keep their layout, and each real value is swapped for a realistic synthetic one.

What to removePage 2 of 3
Checklist

What to remove, and what to keep

Usually removed

  • Names: of people, signatories and contacts
  • Contact details: emails, phone numbers and postal addresses
  • ID and account numbers: national IDs, tax IDs, bank and card numbers
  • Anything you name: add a plain-language instruction such as "also remove the company name"

Usually kept

  • Headings, tables and page layout
  • Amounts, terms and clauses you did not ask to remove
  • The PDF format itself
Tip

Drawing a black rectangle over text in a normal PDF editor often leaves the words underneath, and anyone can copy them out. Re-Doc removes or replaces the underlying text, not just what you see.

How it works

Three steps

  1. STEP 1

    Upload

    PDF, Word, TXT, scan or photo, up to 50 MB. Sign in with Google; the first 10 pages are free.

  2. STEP 2

    Review

    Re-Doc highlights every change. On scans you can add or remove boxes; for any file you can describe what to keep or remove in plain words.

  3. STEP 3

    Download

    Get the safe copy in the same format you uploaded, with the layout unchanged.

Frequently asked questions

01Is it really free?
Yes. The first 10 pages are free after you sign in with Google. No card is needed. After that, paid plans start at $11 a month for 500 pages.
02Do I have to find the personal data myself?
No. Re-Doc detects it automatically and highlights every change. On scans you can add or remove boxes in the editor before downloading.
03Will the redaction be permanent?
Yes. For scans, the pixels under each black box are destroyed. For text-based PDFs, the original value is replaced in the text itself, so it cannot be copied back out.
04How large can the PDF be?
Up to 50 MB per file.
