CHIP - HTML to ePub Converter

Overview

CHIP (Convert HTML Into ePub) is a utility designed to convert a standalone HTML document into a fully formatted ebook in ePub format. CHIP integrates directly into the Windows file explorer context menu. When installed, right-clicking any .htm or .html file will provide the option Convert to ePub. The generated output file shares the base name of the input file with an .epub extension and is saved in the same directory.

Features

• Chapter/Section Detection: Automatically assigns chapter names from headings and embeds each chapter separately into the ePub package.
• Named HTML Entities: Named entities, like Ä (Ä) or α (α), are automatically encoded as UTF-8 characters.
• Table of Contents Generation: Both EPUB2 and EPUB3 compliant navigation files are automatically generated and embedded.
• Asset Embedding: Images referenced within the HTML are automatically detected and embedded directly into the ePub package.
• EPUB Compliance: Output complies with the EPUB v3.3 rules of the w3c EPUBCheck conformance checker.
