Microsoft is giving members of the Microsoft 365 Insider program who also own iPhones and iPads a new feature to test out. They can use the Word iOS app to open and convert PDF files to Word documents. In a post on the Microsoft 365 Insider blog , the company explained the reason why this new feature is being introduced: There are around 2.5 trillion PDFs in circulation across the web and mobile platforms. Despite being a preferred method of sharing information, managing them can be chaotic.
