EPUB vs PDF: E-Reader Reflowable Text vs Fixed Page Print Fidelity
Should you read or publish in EPUB or PDF? Compare responsive reflowable typography, mobile reading convenience, print fidelity, and device compatibility.
EPUB is designed for dynamic reading, automatically reflowing text to fit any screen size or font adjustment. PDF locks content to a rigid digital page canvas, ensuring identical typography, diagrams, and print margins regardless of device.
