AZW3 to EPUB converter

About This Tool

This tool converts AZW3 Kindle ebooks into EPUB format, enabling readers to use common devices and apps. It accepts single AZW3 files or a batch of files, producing corresponding EPUB outputs. The process preserves essential metadata (title, author, publisher, language), table of contents, reading order, cover images, and basic formatting where feasible. DRM-protected files are not decryptable; the tool only processes non-DRMed content. Outputs are standards-compliant EPUB 3.0+ with UTF-8 metadata. It aims to minimize manual reflow or reformatting, facilitating library migration and device-agnostic reading.
Internally, it parses the AZW3 container, extracts HTML/text, images, and metadata, then maps Kindle-specific styling to EPUB equivalents. It rewrites the content into a clean EPUB structure, recreates the spine, manifest, and TOC entries, and validates against EPUB validation rules. Optional features include batch queue, preserving fonts, and embedding cover art. The system operates offline; no data leaves the user's machine.
Ideal for personal libraries, students, publishers, and libraries who need cross-device access. Unique value includes offline processing, metadata retention, and strict adherence to EPUB standards, with batch support and reasonable conversion speed. Typical workflows: convert a single AZW3 for a reader app, or batch-convert a folder of ebooks for a device suite. Use cases include migrating Kindle archives to EPUB-ready formats and compiling accessible copies.
