Please go through the following checklist to make sure your EPUB eBooks play well on Pubu.
- Create an EPUB standard compliant TOC file for your readers to tap and jump to chapter in the table of contents.
- Make sure you have passed Google EPUB check before uploading the eBook.
- Don't forget to split the book into proper chapters, in case there is only one chapter to cause slow loading and crash.
- We also support EPUB 3.0 standard, please contact Support team if you found any incompatibilities with Pubu.
