Question

Auto-tagging fails Accessibility

  • April 7, 2026

Why does the Accessibility Auto-Tag make tags that fail the Accessibility Checker? Every little thing is wrapped up in TH, TR, and TD tags unnecessarily. Workarounds?

    Can you list all the places that I can turn OFF so that Acrobat doesn’t suddenly decide to re-do (and therefore mess up) all my tags? This is important, by the way.

    If you can, please tell how to turn off auto-tagging tendencies in:

    1. In the interface
    2. In Edit > Preferences
    3. Any background processes
    4. Windows Registry edits

    Hi ​@Mike Witherell,

     

    To disable auto-tagging in Adobe Acrobat, open Preferences> (Ctrl+K or Command+K on Mac), select Accessibility> from the categories, and deselect> "Enable cloud-based auto-tagging for accessibility."

     

    More info here: Enhance document accessibility with cloud-based auto-tagging.

    Hi Souvik,

    Thank you! That is 1 of 4 requests, so far. It would be good to have a comprehensive answer on this that includes the other 3 topics.

    Having the Cloud-based tagging turned on in Preferences is worse results than if the preference is turned off. Both make tags that immediately fail the accessibility checker.

    Is there an alternative remediative solution?

    Hello,


    Thanks for reaching out.
    Create a copy of the document and try the following:

    In the meantime, have you tried the Cloud-based auto-tagging feature? 

    1. Create a copy of your document

    2. Launch Acrobat > Menu > Preferences > Accessibility > Other Accessibility options

      1. Check “Enable Cloud-based auto-tagging” for accessibility

      2. Click Ok 

      3. Relaunch Acrobat (optional)

    1. Open the document > Tools > Prepare for Accessibility 

      1. Click “Automatically tag PDF.”

      2. Once done, save the document and check. 

    After you are still required to check the tags manually sometimes.


    To review Auto-Generated Tags: After the auto-tagging process, manually review the generated tags in the Tags panel to ensure that each TH (table header) and TD (table data) is correctly nested within TR (table row) tags.

     

    Correct Tag Structure: 

    Ensure that each TR is a child of Table, THead, TBody, or TFoot.

    Confirm that TH and TD elements are children of TR tags.

     

     

    Use Accessibility Check Tools: 

    Utilize the Full Check/Accessibility Check tool in Acrobat to identify specific tagging errors and accessibility issues. This tool can provide insights into why the tags may not be compliant.

    Access the tool via Tools > Accessibility > Full Check.


    Wait for more inputs from experts.

    Unfortunately the cloud-based tagging is extremely innaccurate, which causes the user to have to manually move tags in the tag tree, which then causes the app to crash.  This is clearly a programming issue and we would just like your company to fix it. It’s been eight days since the latest faulty update, and it seems there’s an issue with each update you’ve sent out.  Your app is almost completely unusable for accessibility tagging at this point. I’ve received instructions on how to collect and submit a crash log, which I will be doing, but the updates should have been tested before the roll out.  I will be suggesting our department uses a different software as this is completely unacceptable with the Title II deadline looming.

    Hi ​@th_4209,

     

    Thanks for writing in! We completely understand your frustration.

     

    Auto-Tagging analyzes spacing, alignment, and borders.

    So, anything that looks like a grid , gets tagged as a tableEven if it’s just layout text (columns, forms, aligned paragraphs).

     

    If working on important and larger documents, the best way to work on documents for accessibility is to tag them on the source document, and then create a tagged copy of the file in PDF (if applicable).

    • Microsoft Word: use styles, proper tables
    • Adobe InDesign: use tagged export

    Then export a tagged PDF.

     

    This should eliminate most of the issues related to accessibility tagging.

     

    Also, instead of sharing a crash log for accessibility related issues, if you can share a sample document along with the accessibility report attached to the file, it would be really helpful for us to investigate the issue further.

     

    Look forward to hearing from you.

     

    Regards,

    Souvik
