Load an EPUB to edit metadata, fix covers, generate TOCs, or bulk find-and-replace text.
✏️ Edit Metadata
🖼️ Cover Image
Checking this automatically updates the OPF manifest and the 'cover' metadata tag.
If the book has no cover wrapper/front-page, this creates a simple front page XHTML that displays the current cover image and inserts it at the start of the spine.
🗂️ Table of Contents
Comma-separated selectors (e.g. h1, h2) to identify chapters.
🔎 Bulk Find & Replace
Define text replacement rules to apply across all chapters (HTML/XHTML files).
