Permanently remove sensitive information from a PDF — names, account numbers, addresses, or any text or region you need to hide. oMyPDF's Redact PDF tool lets you highlight text to auto-detect matches or draw redaction boxes manually, then burns the redactions into the PDF so the content is truly gone — not just covered. Everything runs in your browser — nothing is uploaded.

Frequently asked questions
Is the oMyPDF redact tool free?
Yes. Redacting PDFs is 100% free with no watermark and no sign-up required.
Is the redaction really permanent?
Yes. Unlike just drawing a black box on top, pages you redact are flattened to an image with the black marks burned in, so the underlying text and content are destroyed and can't be copied or recovered.
Can I redact every instance of a word?
Yes. Type a word or phrase in Find & redact and it marks every match across all pages. Review the marks, adjust if needed, then apply.
Will the rest of my document stay searchable?
Pages you don't redact keep their original selectable text. Only pages that contain a redaction are flattened to images.
Are my files safe?
Redaction runs entirely in your browser — your document never leaves your device, which is exactly what you want for sensitive files.
