My friends are asking me to send them my flip album. It’s no problem to send them but the album is too big, so I plan to make it in a less size. But is that achievable?

Yes, you can output the flipping album to a less quality and size.
In the “add file” tab, you can see a page quality option, there are five levels of output file quality and size. High values produce better page quality but require more disk space and more time to download.
