- Device & OS

- Scenario
- Viewing or editing a scanned PDF document that contains unwanted tooltips from alternative text metadata.
- Observed behavior
- A tooltip pops up stating that the page contains a background image with hidden text when interacting with the PDF.
Before removing metadata or hidden text, ensure you have a backup copy of your original PDF, as the sanitization process permanently deletes alternative text and other hidden document data.
Use the Sanitize Document Command in Adobe Acrobat
This is the most effective method for removing hidden text, metadata, and unwanted tooltips from a PDF you did not create.
The Sanitize Document feature is designed to strip out hidden information, including the alternative text that triggers the background image tooltip on scanned documents.
Open your PDF in Adobe Acrobat, navigate to the 'Tools' menu at the top, and select the 'Redact' option.
In the secondary Redact toolbar that appears, click on 'Sanitize Document'.
A dialog box will appear warning you that hidden data will be permanently removed. Click 'OK' to proceed and then save the sanitized PDF file.
Disable Alternative Text in the Source Application
If you are the creator of the PDF, the best approach is to prevent the tooltip from being generated in the first place.

Frequently Asked Questions
Why does my PDF say it has a background image with hidden text?
This occurs in scanned PDFs when optical character recognition (OCR) or document-creation software (like Adobe Acrobat Capture) adds the recognized text behind the image as alternative text or hidden searchable text. The viewer displays a tooltip to notify you of this hidden metadata.
Does the Sanitize Document tool remove anything else besides the tooltip?
Yes, the Sanitize Document tool in Acrobat strips out all hidden information. This includes metadata, hidden layers, comments, attachments, and alternative text. Make sure to save a backup before using it if you need to retain other document properties.
Can I disable tooltips for all PDFs directly in my viewer?
Tooltip display behavior depends on your PDF viewer's preferences. In some viewers, you can disable document tooltips or accessibility pop-ups in the application's General or Accessibility settings, though sanitizing the metadata directly from the file is a more permanent fix that works across all viewers.
