With WaSend you will be able to send throw WhatsApp any file type up to 150MB: documents, videos, music, doc, pdf, zip, rar, apk, mp3, mp4, jpg, png, photos without resizing and without losing quality, etc.
How it works? WaSend hide your files inside video files to "trick" WhatsApp. A video file will be created each 15MB you want to send. It is necessary that the sender sends all the videos, and the recipient downloads them to extract the hidden files.
Both sender and receiver must have WaSend installed to send and receive files.
