Converting from PDF (Portable Document Format) to EPUB (Electronic Publication) helps you work with your content in a different application or workflow. PDF and EPUB serve different purposes, and converting between them bridges the gap.
PDF (Portable Document Format, introduced in 1993) uses Flate, JPEG, JPEG2000, JBIG2, CCITT for embedded content compression. EPUB (Electronic Publication, introduced in 2007) uses ZIP (containing XHTML, CSS, media, OPF manifest) compression. PDF browser support: Universal (built-in PDF viewers in all major browsers). EPUB browser support: None (requires e-reader application).
The quality impact depends on the specific settings used during conversion. EPUB uses compression that may affect quality depending on the chosen settings.
Typical PDF file size: A 10-page text document: ~100-300 KB; with images: ~1-10 MB. Typical EPUB file size: A 300-page novel: ~500 KB - 2 MB; illustrated book: ~10-50 MB.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
