We help people easily write keepsake books in their browser from single stories they write in separate sections. Meminto then assembles all the snippets into the finished book.

Currently, we display a preview using xpdfeditor.js – but some books have 300-500 pages, and if an unwanted line break occurs on page 50, it can't be easily adjusted in the PDF.

How could we solve this differently so that there is a clean page view, where the page breaks really match the printed book?
