-## What is “how to extract EPUB”?
-Extracting EPUB means reading the internal XHTML/HTML files, CSS, and metadata packaged inside the EPUB container and presenting that content in a usable form—often plain text or HTML. GroupDocs.Parser abstracts the container handling, giving you clean, ready‑to‑display HTML without manual zip processing.
+## What is “extract epub to html”?
+Extracting EPUB to HTML means reading the packaged XHTML/HTML files, CSS, and metadata inside the EPUB container and outputting that content as standard HTML. GroupDocs.Parser abstracts the ZIP handling, delivering clean HTML without manual extraction, while preserving the original layout, headings, and basic styling for immediate web display.
 
 ## Why use GroupDocs.Parser for Java to convert EPUB to HTML?
-- **Preserves formatting** – headings, paragraphs, lists, and basic styling are retained.  
-- **Cross‑platform** – works on any OS that runs Java 8+.
