My epub output is around 100 MB. How do I optimize it to reduce the size?
What’s in it? Images? Tables? Just a lot of words?
I think the culprit was the images. I reoptimized it to get it down to 60MB
An e-book is a website in a Zip-file, so essentially already compressed. Images are usually the culprits, reduce those in size to reduce the resulting e-book’s file-size.
