Redact PDF Permanently Free Online
Permanently redact PDF content online free. Securely remove sensitive text and images from PDFs forever.
About Redact PDF Permanently
Permanently redact sensitive information from PDFs so it cannot be recovered, copied, or revealed by zooming. PDF AI Tools replaces selected content with solid blocks at the PDF content-stream level — not as a removable annotation.
Most PDF annotation tools let you draw a black rectangle that can be removed by any reader. Permanent redaction modifies the underlying content stream so selected text and images are gone from the file structure itself.

Frequently Asked Questions
What is the difference between this and drawing a black box?
A drawn box is a PDF annotation that any reader can remove. Content-stream redaction physically removes the data from the PDF.
Can the redacted content be recovered by any tool?
No — the content is replaced in the PDF object model, not hidden behind an overlay.
Does it work on images inside PDFs?
Yes — image areas are overwritten with opaque rectangles, removing the pixel data.
Is this suitable for FOIA and legal discovery?
Yes — content-stream redaction meets the technical standard for legal document production redaction.
