“EPUB is not plain text; rather, it is a package similar to a web page. Improper translation can cause the table of contents to become unclickable or lead to incorrect jump positions.”

Root Cause Analysis

Preserving HTML Structure Integrity

The internal structure of an EPUB is stored in HTML format. During translation, Shangyi AI strictly preserves all <a> tags (links) and ID anchors. Once the translation is complete, repackage the file to ensure that the translated book’s navigation and table of contents correspond precisely with the original.

Multilingual Covers and Metadata

We translate not only the main content but also make every effort to synchronize the translation of the book’s metadata—such as title, author, and description—so your digital bookshelf remains tidy and consistent.

Final Solution Summary

You can enjoy the convenience of clickable table of contents navigation and in-text note access, just as you would when reading the original.
