WhatsApp is one of the most popular IM apps that not only used to communicate via text but also deals in the exchange of music, videos, pictures, and even your current location. The number of active users is over 600 million and is available on multiple platforms such as iOS, Android, and Windows. But the service comes with file size limitation. How big is it and how can you overcome it? WhatsApp Video File Size Limit To keep its servers intact, WhatsApp limit the attachment file size. Anything that you share using the app couldn’t exceed the 16 MB. The limit won’t likely affect your texts, nor your images unless you are sharing the highest quality photos from a high-end SLR.
