Redact PDF Documents
Permanently hide sensitive information from your PDF files. Draw redaction boxes over text, images, or any content you want to remove — securely and irreversibly.
About PDF Redaction
Confileo's PDF Redaction tool permanently removes sensitive text and information from a PDF. Everything runs in your browser, free and without signup, and your files are deleted automatically after processing.
Hiding sensitive information with a black box is dangerous — the text underneath can still be copied or recovered. True redaction removes the data permanently, which matters for lawyers, HR teams and anyone sharing official documents.
Confileo's PDF Redaction tool deletes the underlying content — ID numbers, bank accounts, names — rather than just covering it, so it cannot be retrieved. Mark the text or areas, download the redacted file, and the rest of the document stays intact.

PDF Redaction — Frequently asked questions
Is the redacted text truly removed?
Yes. Redaction removes the underlying content — not just a black box you can copy behind.
Can redacted information be recovered?
No. Once redacted and downloaded, the removed content cannot be retrieved from the file.
How do I permanently delete sensitive info from a PDF?
Mark the sensitive text or area, apply redaction, and download a file with that information fully removed — not just hidden.
What is the difference between redaction and a black box?
A black box can be removed or copied behind. Redaction here deletes the underlying data so no trace remains.
Can I use it to hide ID numbers or bank accounts?
Yes. Ideal for removing ID numbers, bank accounts and names before sharing contracts and official documents.
Does the rest of the document stay intact?
Yes. Only what you marked is removed; the rest of the content and formatting stays unchanged.
Can I redact images, not just text?
Yes. You can cover any area of the page, including images, logos and signatures, and the content underneath is removed.
Once redacted, can the hidden text still be copied or searched?
No. The underlying text is removed, so it cannot be selected, copied or found by search.
Is this safe for official or legal documents?
Yes. Because the content under each redaction is deleted rather than just hidden, it is suitable for sharing sensitive or legal documents.
Is this tool really free?
Yes. Every Confileo tool is free to use with no daily caps, no watermark on your output and no credit card required.
Do I need to create an account?
No. You can use the tool straight away without signing up or logging in.
Are my files safe and private?
Yes. Your files are processed for the task you requested and then deleted automatically — they are never shared or kept.
Does it work on my phone?
Yes. The tool runs in any modern browser, so it works the same on desktop, tablet and mobile with nothing to install.
