- Product
- PDF Accessibility Checker 3.0
- Device & OS
- not provided
- Scenario
- Running an accessibility check on a PDF document and encountering empty tag errors.
- Observed behavior
- Deleting the empty tag's content object prevents the PDF document from opening or saving correctly.
Before making structural changes to your PDF tags, save a backup copy of the original document to ensure you can revert if the document layout or readability is inadvertently affected.
Change the Empty Tag to a Page Artifact
Convert the problematic content object into a page artifact rather than deleting it to maintain document integrity while passing accessibility checks.
Deleting content objects associated with empty tags is not recommended. Doing so removes essential structural elements from the PDF code, which typically corrupts the file or causes untagged-content errors. Converting the tag to an artifact safely tells screen readers to ignore the empty space without breaking the document.
Open the tags tree panel in your PDF editing software or PDF Accessibility Checker and locate the specific empty tag causing the error.
Right-click on the specific content object associated with the empty tag to open the options menu.
Select 'Change Tag to Artifact' from the available menu options.
In the dialog box that appears, set the artifact type to a 'Page artifact' and click 'OK' to apply the change.
Save the file, ensure the document remains readable, and re-run the accessibility check to confirm the empty tag error is resolved.

Frequently Asked Questions
Why does deleting an empty tag corrupt my PDF document?
Deleting a tag's content object completely removes underlying structural data required by the PDF format. This unexpected structural loss can trigger critical errors when the software attempts to read, open, or save the document.
What is a page artifact in PDF accessibility?
A page artifact is a graphical or structural element in a PDF (such as a decorative background, a line, or a layout empty space) that does not contain meaningful text. Marking an element as an artifact instructs screen readers and accessibility checkers to safely ignore it.
Can an empty tag cause my PDF to fail an accessibility check?
Yes. PDF Accessibility Checkers (like PAC 3.0) frequently flag empty tags because accessibility standards require all structural tags to contain readable content, alternative text, or be explicitly designated as artifacts.
