WhatsApp long had the ability to share files like audio, video, and photos. However if you wanted to share documents over the app, you’d either have to send the person an email or a link to Dropbox, Google Drive. and etc. Basically directing sending of documents is not possible through the app, at least until now.
WhatsApp has recently received an update that allows users to send each other documents. At the moment it seems that only PDF files are supported, but presumably it will be expanded in the future to accommodate more file types. We can imagine that eventually it could support Microsoft Office files or Pages, Sheets, and Slides, but for now PDF is the only format that works.
In addition to the ability to send documents, the update also presents a new design for browsing photos and videos compared to before. There are also new wallpaper options in which users can now select from solid colors, as opposed to various patterns and designs that WhatsApp used to offer.
The update is now live and should be available for all users, so if you haven’t updated your WhatsApp yet, head on over to the iTunes App Store or Google Play to get your hands on it.
