- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Fixing incorrect language attributes in PDF tags to ensure proper document compliance and accessibility.
- Observed behavior
- Adobe Acrobat does not feature a built-in automated Preflight fixup that strips out language attributes globally across all elements.
Before modifying structural tags, ensure you have a backup of your original PDF document, as deleting or altering tags can heavily impact accessibility features and screen reader compatibility.
Create a Preflight Check and Manually Correct Tags
Configure a custom Preflight profile to isolate unexpected language attributes in your structure elements, then clear them manually.
Adobe Acrobat does not include a built-in automated fixup to globally remove all 'Lang' attributes from structure elements or marked-content sequences.
Instead, you can create a custom Preflight check to identify any language attribute that does not match your expected primary language. Once identified, you can manually clear or correct the specific tags.
Go to 'Tools', select 'Print Production', and then click on 'Preflight' to open the profile configuration dialog box.
In the Preflight window, select 'Options' and then 'Create New Preflight Check'. Set the target to search for structure elements and marked-content sequences.
Add a condition to flag any 'Lang' attribute that does not start with your expected language code (for example, check for any language attribute NOT starting with 'en' for English).
Execute the newly created Preflight profile. This will generate a report listing all elements that contain an unexpected language attribute.
Open the 'Tags' navigation pane on the left sidebar. Locate the flagged structure elements, right-click each one, choose 'Properties', and delete or correct the text in the 'Language' field.

Frequently Asked Questions
Why do PDF tags have language attributes?
Language attributes in PDF tags define the specific language of a text segment. This is essential for assistive technologies, such as screen readers, to accurately pronounce words and switch audio dictionaries on the fly.
Can I simply delete all tags to remove the language attributes?
Yes, but it is highly discouraged. Stripping all tags from a PDF will completely destroy the document's logical reading order and accessibility compliance. It is much better to identify and correct the specific faulty tags.
How do I view the language of a specific tag in Acrobat?
Open the Tags panel from the left sidebar, right-click the specific structure element, select Properties, and view the 'Language' field under the Tag tab.
