Based on our record, FlowPaper should be more popular than UpContent. It has been mentiond 5 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
But, in an effort to help you find peace too, you can give upcontent.com a try. They want $15 a month though last we checked and only stayed with Feedly because of its much more robust delivery (and where upcontent wanted hundreds a month for their API extra). Source: almost 2 years ago
I've used FlowPaper for a few projects in the past: https://flowpaper.com. Source: about 2 years ago
Https://flowpaper.com/ will do this. I saw your comment about not wanting to use 3rd party, but you just cannot do this with InDesign alone. Source: about 2 years ago
Have a look at using FlowPaper for this (https://flowpaper.com). Flowpaper splits the publication in chunks and compresses the output. A 1000- page publication will load just as fast as a 10 page publication after it's been processed. Source: over 2 years ago
I would recommend using something like FlowPaper instead of supplying the PDF https://flowpaper.com/. Source: over 2 years ago
We make a lot of booklets for clients and quite a lot requested an online version. Rather than recreate the entire thing in HTML we found FlowPaper that converts PDF's to flip books. It's pretty versatile (though heavy on data), but it actually converts PDF's very well, which is surprising. It might not be what you're after though! Source: almost 3 years ago
