There are 2 differences between import multi-PDF and batch conversion.
1. Importing multi-PDF means merging multiple PDFs(total size<1G, total pages<1000)into one flipbook.

After importing multi-PDF, you can further customize your flipbook such as adding a template, theme, scene, table of contents, bookmark, voice assistant audio and multimedia.

Before batch conversion, you can click [Edit] to apply a template to all your flipbooks at one time, which is time-saving and convenient for users.
