How WhatsApp Storage Usage granular controls work

To use this feature on Android, you need to be on the latest beta - v2.17.340. Head to Settings -> Storage Usage on your Android beta app and clear all the unwanted space-hoarding files easily. In this menu, WhatsApp will let you choose message types, such as videos, text, images, GIFs, voice messages, etc. from specific chats - here you can delete exactly what you want and keep the rest.
Once you select the chat you want to clear, there will be a 'Manage messages' option at the bottom of the screen. Clicking on it will let you select the content that you want to delete, for example, you can choose to delete all GIFs and videos from a specific chat to free up space, or just delete all the text messages and let the other content remain.

WhatsApp Storage Usage granular control are only in beta stage on Android

New WhatsApp features

It is among the  slew of features whatsapp has introduced this year, while some more are rumoured to be on the way. Among the biggest changes was the debut of the photo/video-based Status, in-app YouTube playback, two-step verification, text-only statuses in colour, photo bundling, video streaming, photo filters, night mode in camera, Quick Reply button, Pinned Chats, live location sharing, and verified profiles for businesses. Integration with UPI is also expected soon, but the most anticipated WhatsApp feature of 2017 will be the 'Delete for Everyone' option that will let you un-send messages.
