InstallableBook vs. PDF.
Compare responsive, installable reading with fixed-layout PDF distribution.
The practical difference
PDFs preserve a page exactly, which is valuable for forms and fixed layouts. An InstallableBook reflows text for the reader’s screen, provides chapter navigation and can be saved as a standalone Home Screen reading experience.
Which should you choose?
Choose PDF when exact page geometry matters. Choose InstallableBook when comfortable long-form reading, navigation and direct distribution matter more.
InstallableBook is additive
Many publishers can use an InstallableBook alongside PDF, EPUB, Kindle or print editions rather than replacing every existing format.
