How to Redact a PDF Free Online (Permanently, No Account)
Permanently redact sensitive information from a PDF online for free — black out text, names, and numbers. No account, no server upload.
PDF redaction permanently removes sensitive information — names, addresses, account numbers, confidential data — from a document before sharing it publicly. FixMyPDF's redaction tool does this in your browser for free, with no account and no upload to any server.
What PDF Redaction Actually Means
True redaction permanently destroys the underlying data beneath the black box. Simply drawing a black rectangle over text in Acrobat or Preview doesn't redact — the text is still in the PDF and can be selected, copied, or even revealed by removing the rectangle. Proper redaction removes the content from the file completely.
How to Redact a PDF Online for Free
Go to fixmypdf.in/tools/redact. Upload your PDF. Click and drag to draw redaction boxes over sensitive content on each page. Click "Apply Redactions" — the content under each box is permanently removed and replaced with a solid black rectangle in the PDF structure, not just overlaid.
What to Redact
Common redaction targets in legal and business documents: personal names in medical or legal records; account numbers and financial data in shared reports; addresses and contact information in FOIA-requested documents; signature fields containing real signatures; confidential clauses in contracts sent for non-confidential review.
Redaction vs Drawing a Black Box
A drawn black rectangle in most PDF editors is an annotation layer — the underlying text remains selectable. True redaction removes the underlying content. After applying redaction with our tool, attempt to select text in the redacted area — nothing will be selectable, confirming permanent removal.
Privacy: Why In-Browser Redaction Matters
If you're redacting sensitive information before sharing, the last thing you want is to upload the unredacted version to a server where it might be logged, cached, or stored. Our browser-based processing ensures the sensitive original never leaves your device — redaction happens entirely in your browser.
Redacting Metadata Too
When sharing a redacted PDF, also remove metadata that might contain sensitive information — author name, organisation, original creation date, GPS data from embedded images. Use our metadata remover after redacting for complete document sanitisation.
After Redacting
Once redacted, verify by trying to select text in the redacted areas. Then compress the redacted PDF for smaller file size before sharing. The black boxes don't add significant file size, but redaction may remove large blocks of text/image data that compress well.
