Regardless of the application used to create them, PDF files creates a static image — a picture — of each page. From the author’s point of view this is a godsend, because content will always display the same way for every user. For users, however, there is a downside. Precisely because .pdf text is not reflowable, it will not resize to fit each device or user setting. This means some users on some devices will need to zoom in and out to read the entire text.
While EPUB is designed for reflowable text — meaning text that adjusts itself depending on the size of the display, the font being used (if the user is able to change fonts), the size of the text, and various other variables.
