Redact PDF Online Free
Permanently remove sensitive information from a PDF. Draw black boxes over anything private, and the pages are flattened so the hidden content can’t be recovered — all in your browser, nothing uploaded.
Frequently Asked Questions
Is my PDF uploaded to a server?
No. Redaction runs entirely in your browser. Your sensitive document never leaves your device.
Is the redacted content truly removed?
Yes. To guarantee the underlying content is gone, each page is flattened to an image with the black boxes baked in — the hidden text cannot be copied or recovered.
Why does the output lose selectable text?
Because true redaction requires flattening the page to an image so nothing remains underneath the black boxes. That is the trade-off for guaranteed removal.
Can I redact multiple pages?
Yes. Navigate between pages and draw as many redaction boxes as you need on each one.
Is it free?
Yes — completely free, no account, no watermark, no limits.
