Question details
The user needs to count the number of stamp annotations in a PDF, categorized by stamp type and specific pages.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Managing and tracking specific PDF stamps across multiple pages in a large document for auditing or review purposes.
- Observed behavior
- The user requires exact counts for each type of stamp per page, which involves identifying the stamp's internal name through scripting or manual filtering to generate an accurate total.
Ensure that all stamps have been successfully applied to your PDF document and note that JavaScript solutions require the internal name of the stamp, which may differ from its visible label.
Count Stamps Manually via the Comments Panel
Use the built-in filtering tools in the comments panel to quickly view and count stamp annotations without writing any code.
This method is ideal for users who need a quick visual count of their stamps. By isolating stamps from other annotations, the panel automatically displays the total number.
Navigate to the right-hand pane in your PDF editor and click on the 'Comments' or 'Annotations' icon to open the full list of document markups.
Click the filter icon (usually shaped like a funnel) at the top of the Comments panel. Select 'Stamps' from the list of annotation types to hide all other comments.
Look at the top or bottom of the filtered Comments list. The panel will display the total number of filtered items, giving you your document-wide stamp count.
Use Acrobat JavaScript for Automated Counting
Implement a custom JavaScript to scan annotations, match internal names, and calculate precise totals per stamp type and page.

Frequently Asked Questions
Why does my JavaScript not recognize the PDF stamp name?
When using JavaScript, you must use the stamp's internal system name (often found in the AP property) rather than the visible label displayed in the user interface. Custom stamps typically have unique, auto-generated internal names.
Can I filter other types of annotations besides stamps?
Yes. The comments panel in most professional PDF editors allows you to filter by various annotation types, including highlights, text boxes, sticky notes, and drawing shapes.
Are PDF stamps counted as regular comments?
Yes, standard PDF stamps are treated as annotation objects. This means they will appear alongside text comments and highlights in your document's comment list.
Do I need programming skills to count PDF stamps?
Not necessarily. If you only need a basic document-wide count, you can use the built-in filter feature in the Comments panel. Programming skills are only required if you want to automate page-by-page breakdowns using JavaScript.
