Question details
The user needs a solution or workaround to prevent Adobe Acrobat Pro from freezing when applying redactions to a PDF document.
- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Applying redactions to hide sensitive information in a PDF document, often under tight deadlines.
- Observed behavior
- A blank confirmation dialog appears after applying redactions, causing the application to freeze completely and requiring a force-quit via Task Manager.
Before applying these workarounds, ensure you have saved a backup copy of your original unredacted PDF, as forceful closures via Task Manager can lead to document corruption.
Print the Document to Adobe PDF as an Image
Bypass the redaction dialog bug by flattening the PDF document into an image before applying the redaction marks.
This method converts the entire document into a flat image, which eliminates the underlying text layers that often trigger the redaction glitch. Note that this will increase the file size and make the document text non-searchable.
Open your PDF document in Adobe Acrobat, go to File, and select Print.
Select 'Adobe PDF' from the printer dropdown list. Click on the 'Advanced' button and check the box for 'Print as Image'.
Click OK and then Print to save the new PDF file. Open this newly created file, apply your redactions, and verify the document before distribution.
Force Redaction via JavaScript Debugger
Use a quick console command to execute the redaction process without triggering the buggy confirmation dialog box.
Redact PDFs Smoothly with WPS Office

Frequently Asked Questions
Why does Adobe Acrobat freeze when I apply redactions?
This is a known software glitch in certain Acrobat updates where the confirmation popup fails to render properly. It results in an invisible or blank dialog box that blocks the application interface, making it seem frozen.
Will the 'Print as Image' workaround increase my PDF file size?
Yes, printing a PDF as an image removes standard text layers and vector data, converting pages into flat images. This typically results in a significantly larger file size and makes the text non-searchable.
Is the JavaScript debugger solution permanent?
No, the JavaScript console command 'this.applyRedactions();' is a temporary workaround for the current document session. You will need to run the script each time you wish to apply redactions until an official patch is released.
Can I recover my PDF if Acrobat crashes during redaction?
If Auto-Save is enabled, Acrobat may prompt you to recover the document upon restarting. However, to prevent data loss, it is highly recommended to manually save a copy of your document before initiating the redaction process.
