EPUB vs PDF: Digital Reading Format Comparison

EPUB and PDF solve opposite problems. EPUB is reflowable: text adapts to any screen size, font and reader preference — the native language of e-readers. PDF is fixed: pages render identically everywhere, which is essential for print-like documents and terrible for small screens. Choosing between them is choosing between comfortable reading and faithful layout.

Feature	EPUB	PDF
Layout Model	Reflowable — adapts to screen	Fixed — pages never change
Small Screens	Excellent (text rewraps)	Poor (zoom/pan required)
Standard	Open standard (W3C, EPUB 3)	Open standard (ISO 32000)
