Acrobat Action : Tooltips Remover
Tooltips Remover is an Action for Acrobat 10, 11 and DC
You asked Acrobat to automatically detect form fields and now your newly made form is full of nice hundreds fields.
Well, but… on roll-over each of these hundreds fields display a yellow Tooltip, made from the field name and often not really relevant, so it may be confusing for end users.
⇒ Tooltips Remover removes all tooltips from all form fields in a PDF form.
