Redact PDF Online
Permanently remove sensitive information from PDFs before sharing. True redaction deletes data — not just hides it.
PDF redaction is the process of permanently removing sensitive, confidential, or private information from a document. Unlike covering text with a black box, true redaction deletes the underlying data so it can never be recovered, copied, or searched.

Redact PDFs with OmnisPDF
PDF Redaction is available on our Business plan. Permanently remove sensitive text, images, and metadata from your documents.
Legal and Regulatory Compliance
Courts, government agencies, and healthcare organizations require that sensitive data be permanently removed from documents before they are shared or filed publicly. PDF redaction is the standard method for meeting these requirements under HIPAA, GDPR, FOIA, and court rules.
HIPAA and GDPR Requirements
HIPAA mandates that protected health information (PHI) be permanently removed before sharing medical documents. GDPR requires that personal data be properly anonymized when fulfilling data subject requests. Simply covering information with a black box does not meet these standards — true redaction is required.
Permanent vs. Visual Redaction
Visual redaction (placing a black rectangle over text) is a common mistake. The text remains in the file and can be copied, searched, or extracted using free tools. True redaction permanently deletes the data from the PDF. OmnisPDF uses true redaction to ensure your sensitive information is completely gone.

Frequently Asked Questions
What does it mean to redact a PDF?
Redacting a PDF means permanently removing sensitive information — such as names, Social Security numbers, financial data, or confidential text — by blacking it out so it cannot be recovered or copied.
Is PDF redaction truly permanent?
Yes. Unlike simply placing a black rectangle over text, true redaction permanently deletes the underlying data from the file. The redacted content cannot be recovered, copied, or searched.
What is the difference between redaction and hiding text?
Hiding text with a black box is purely visual — the text is still in the file and can be copied or extracted. Redaction permanently removes the data from the PDF, making it impossible to recover.
Is PDF redaction required for HIPAA and GDPR compliance?
Yes. HIPAA requires that protected health information (PHI) be permanently removed before sharing documents. GDPR requires that personal data be properly anonymized. PDF redaction is the standard method for meeting both requirements.
Does OmnisPDF offer PDF redaction?
Yes. PDF Redaction is available on OmnisPDF's Business plan ($13.99/month). It permanently removes sensitive text, images, and metadata from your documents directly in your browser.
What types of content can be redacted from a PDF?
You can redact text (names, addresses, account numbers), images (photos, signatures, logos), and metadata (author name, creation date, software info). OmnisPDF's redaction tool handles all three types.
