What EPUB versions does this tool support?

The tool supports both EPUB 2.0 and EPUB 3.0 formats. It can parse the container.xml, content.opf, and toc.ncx/toc.xhtml files to extract comprehensive information.

Is my EPUB file uploaded to a server?

No, for basic analysis the tool works entirely in your browser using JavaScript. Your EPUB file never leaves your computer. Only if you use advanced analysis features requiring server processing will the file be sent to our secure servers.

What information can I extract from an EPUB file?

You can extract: metadata (title, author, publisher, language), chapter structure and table of contents, word and character counts, embedded images and their details, embedded fonts, file structure validation, and overall EPUB composition insights.

Is there a file size limit?

There's no strict file size limit for browser-based analysis. However, very large EPUB files (over 100MB) may take longer to process depending on your device's memory and processing power.
