You can share a lot of things on WhatsApp: images, videos, audio, locations, and documents. But for some reason, the company has long limited you to just a few specific file types, like PDFs, Word documents, speadsheets, and slides. If you tried to share anything else, the files would be greyed out.
One neat benefit to this is that it allows you to send images and video without the usual WhatsApp compression, although 100MB is quite a small limit for modern high-resolution video. We imagine that limitation is there to not overwhelm WhatsApp’s servers with people sharing things like 4K movies.
It’ll come in handy for sure. There have been plenty of times I’ve wanted to share different file types through WhatsApp, such as APKs. In those cases I’d usually just upload things to a cloud service like Dropbox or Google Drive, but this should allow you to share files in fewer steps.
All that being said feature appears to be limited to a small number of users for now, but we imagine it will roll out to everyone soon enough. We’ve contacted WhatsApp for more information and will update this post if we hear back.
