Use the Mark Redaction tool to first mark content, then permanently remove the data by applying redaction. Redaction marks appear as solid, colored boxes.
With Redaction tools, you can mark those visible contents including text, graphics and images in PDFs, and then permanently remove them (the data) from the PDFs by applying redaction on them. Redaction marks commonly appear as colored boxes with filled-in solid color, but you can also set it to display codes, custom text, or just a blank area.
To permanently redact content from your document:
- With the Redaction Tool Properties dialog, set your Redaction mark appearance. See Setting Redaction Properties.
- Select the Mark Redaction tool at Document > Redaction > Mark Redaction or click the icon on the Task > Redaction toolbar.
- Do one of the following to mark the content you want to remove:
- Move your pointer around or over text and select the text you want to remove when the cursor changes to .
- Move your pointer to an area with no text When the cursor changes to , drag a rectangle box to cover the entire selected area.
Note: When hold the pointer over a marked area, it will preview how the redaction marks will look when applied.
- Right-click one marked area and select Apply from the context menu to apply it permanently. If you want to apply all marked areas in the current PDF, select Apply All.
- In the pop-up Apply dialog box, check which types of content covered by the marked area to remove. If you check the option Remove all references to the marked contents, all referred object data will be remove from the PDF. Click Apply to execute redaction.
Note: Redaction can not be undone after it is applied. To avoid inadvertent mistakes, we strongly recommend you to prepare a copy of the original PDF before you execute redaction handling; or save the redacted PDF as a new file with a different name, location or both.
