Practical guide
What is Redact PDF Online?
Redact PDF Online permanently removes sensitive information from PDF pages so it cannot be selected, searched, or copied from the redacted areas.
Unlike drawing a black box on top of text, Converto rewrites every page that contains a redaction as a high-resolution image after overwriting the selected regions. That destroys underlying text, vectors, and image pixels on those pages. Search for names, emails, and phrases; click selectable text; or draw regions on scans. Metadata is cleared on the rewritten output. Untouched pages keep their original vector content.

Helpful answers
Frequently asked questions
Quick answers about redact pdf online and how this page works.
Is this the same as covering text with a black box?
No. Affected pages are rewritten so underlying text and pixels in marked regions are destroyed, then appearance boxes/labels are burned into the image.
Can I redact scanned PDFs?
Yes. Draw rectangular regions on page previews. Those pages are rasterized with the marked pixels overwritten.
Is Redact PDF free?
No. It is a premium Converto tool with private storage and 24-hour cleanup.
Will metadata be removed?
Title, author, subject, keywords, and related metadata fields are cleared on the rewritten output.
