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.
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.
