Common FAQ about Top 7 PDF Redaction Tools to Redact Content in PDF for Free

Q:Why can't I apply redactions in Adobe?

If the PDF redaction tool doesn’t work in Adobe Acrobat, the PDF might be locked. You can go to “File” > “Properties” to change the security settings. Or, choose “Tools” > “Protect” > “Encrypt” > “Remove Security” to remove the protection. If you are not the owner of the document, contact the author.

Q:Can I redact a secured PDF?

You can redact a password-protected PDF in two ways. One is to enter the correct password within a PDF software program to get editing permission. The other is to use a PDF password remover to get rid of the security restriction for PDF redaction.

Q:How do I black out text in a PDF without redacting it?

To black out the text in a PDF file without redacting it, use the PDF annotation feature in a PDF software program to add a shape over it. In SwifDoo PDF, navigate to “Annotate”, click the “Shape” drop-down arrow to choose “Rectangle”, draw a rectangular area around the text and fill the shape with a color you like. Covering, blurring, or blacking out content with shapes will not permanently remove it and others can delete the shapes to get the content later.
