Why eBook Conversion Matters
Device Compatibility
The primary reason for converting eBooks is compatibility. Major eReaders each have their preferred formats:
Barnes & Noble Nook: EPUB
Kobo eReaders: EPUB
Apple Books: EPUB, PDF
Generic smartphones/tablets: EPUB, PDF
Without conversion, you risk being unable to open your eBook on your preferred device.
Enhanced Reading Experience
Different formats offer varying reading experiences:
EPUB/MOBI: Adjustable fonts, resizable text, reflowable content
PDF: Fixed layout preserves formatting but lacks adaptability
TXT: Universal compatibility but no formatting
Conversion allows you to choose the format that best suits your reading needs.
File Management & Sharing
Converting eBooks enables:
Reduced file sizes for storage
Standardized formats for sharing
Cross-platform accessibility
