How to Add Purpose or Overlay Text to a PDF Redaction
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Applying privacy or freedom-of-information (FOIA) exemption codes to redacted PDF content.
Observed behavior
The user wants to display custom text or predefined redaction codes directly over the blacked-out sections of a PDF document.
Before you start

Ensure you have Adobe Acrobat Pro installed, as the redaction tool is not available in the free Adobe Acrobat Reader. It is highly recommended to save a backup copy of your original PDF before applying any permanent redactions.

Solution 1Recommended

Add Overlay Text via Redact Tool Properties

Configure your overlay text settings before applying redaction marks to ensure all subsequent redactions automatically display the chosen text or code.

By setting the properties before marking your document, you can streamline the process of applying uniform exemption codes across multiple pages.

1
Open the Redact Tool

Open your PDF in Adobe Acrobat, navigate to the 'Tools' menu, and select 'Redact'.

2
Access Redaction Properties

Click on 'Properties' in the secondary Redact toolbar to open the Redaction Tool Properties dialog box.

3
Enable Overlay Text

Check the box next to 'Use Overlay Text' located under the Appearance tab.

4
Choose Text or Code

Select 'Custom Text' to manually type your own label, or select 'Redaction Code' to choose from built-in FOIA or U.S. Privacy Act codes from the dropdown menu.

5
Apply the Redaction Mark

Click 'OK' to save the settings, then highlight the text or draw a rectangle over the area you wish to redact. The chosen text will appear over the redaction marks.

Customizing the Appearance: You can change the font style, size, and color of the overlay text in the same Properties dialog to ensure it is easily readable against the redaction fill color.

Frequently Asked Questions

Can I add custom redaction codes in Adobe Acrobat?

Yes, you can add custom redaction codes. In the Redaction Tool Properties, select 'Redaction Code', click 'Edit Codes' at the bottom of the window, and use the interface to add new code sets or individual entries tailored to your organization.

Why is my overlay text not showing up on the redaction?

Overlay text will only appear if the 'Use Overlay Text' option is checked in the Redaction Properties. Additionally, ensure that the font color selected contrasts with the redaction fill color (for example, choose white text if your redaction fill is black).

Can I change the font size and color of the redaction overlay text?

Yes. When you open the Redaction Tool Properties or right-click a redaction mark to view its specific properties, you can customize the font, size, color, and alignment of the overlay text under the Appearance tab.

Is redaction permanent in Adobe Acrobat?

Redaction becomes permanent only after you click 'Apply' in the Redact toolbar and save the document. Once applied and saved, the underlying text or images are permanently removed and cannot be recovered.
