Converting from DOCX (Office Open XML Document) to EPUB (Electronic Publication) helps you work with your content in a different application or workflow. DOCX and EPUB serve different purposes, and converting between them bridges the gap.
DOCX (Office Open XML Document, introduced in 2007) uses ZIP (containing XML parts) compression. EPUB (Electronic Publication, introduced in 2007) uses ZIP (containing XHTML, CSS, media, OPF manifest) compression. DOCX browser support: None (requires office application or online viewer). 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 DOCX file size: A 20-page report with images: ~500 KB - 5 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.
