Understanding ePub and PDF: Why Conversion Matters
What is ePub?
The ePub (Electronic Publication) format is designed for reflowable content. It adapts dynamically to:
Screen size
Font size preferences
Reader settings (night mode, accessibility features)

What Is PDF?
PDF (Portable Document Format) preserves every design detail:
Fonts and typography
Page layout and margins
Images and graphics
Fixed page order
PDF is universally supported across all platforms, making it ideal for printing, archiving, professional distribution, and academic submissions.
