How to Fix Misaligned PDF Redaction Marks in Acrobat
Question details
The user needs to correct the alignment of redaction marks that are improperly covering the text underneath the selected area.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Redacting sensitive text in a PDF document using the standard selection tool.
- Observed behavior
- The Acrobat redaction tool places a black mark below the selected text, partially covering the line underneath instead of the intended text.
Verify that your PDF document is not a poorly scanned image, as misaligned OCR (Optical Character Recognition) text layers frequently cause the text selection tool to snap to the wrong baseline.
Define a Custom Redaction Area Using the Control Key
Bypass the default text selection snapping behavior by manually drawing the exact redaction box.
When Acrobat's text selection tool detects invisible formatting or overlapping text baselines, it may snap the redaction mark to the wrong line. Overriding this snapping behavior allows you to pinpoint the exact redaction area.
Open your PDF in Acrobat, go to the 'Tools' menu, and select the 'Redact' option.
Instead of clicking and dragging normally, press and hold the 'Control' (Ctrl) key on your keyboard.
While holding the Control key, click and drag your cursor over the exact text you want to redact to draw a precise rectangle.

Adjust Redaction Tool Properties
Change the redaction mark's visual properties to avoid obscuring nearby lines with thick borders or incorrect fill colors.

Frequently Asked Questions
Why is my PDF redaction selecting the wrong lines?
This often happens due to invisible formatting layers, misaligned OCR text, or irregular line spacing in the PDF file. These issues cause the automatic selection tool to snap to the wrong baseline. Manually drawing the redaction area usually bypasses this error.
Can I remove a redaction mark after drawing it?
Yes. Before you apply the redactions and save the document, you can select the redaction mark and delete it. However, once applied and saved, redaction permanently removes the underlying text and cannot be undone.
How do I change the color of the redaction mark from black to white?
Before marking the text, right-click the redaction tool to open its Properties. From there, you can change the 'Fill Color' setting from the default black to white or select 'No Color' so it blends perfectly with your document's background.
