What is Compatibility Mode in Word?

Compatibility Mode activates when you open a document created in an older version of Word (.doc format or older .docx). It disables newer features to prevent formatting issues if the document is shared with people using older Word versions.

Will converting from Compatibility Mode change my document?

Converting may slightly adjust formatting, especially for equations, text boxes, and SmartArt. Save a backup before converting. Most documents convert without visible changes.
