What changes in the EPUB?
You choose the title, author, language and any associated sorting or alternate-script values to update. Multiple entries stay separate. The EPUB 3 modification date is updated when needed. Chapter text, images, styles and the book identifier stay unchanged.
Will my reader show the new values?
This changes metadata inside the file. It does not change words printed on the cover, translate the book, update retailer listings or clear a reader’s cached information. The language tag does not change the language markup inside chapters.
Can I edit a book with errors?
You can supply a missing title or language when the package can be read safely. Other structural errors may still block the checked download. For broken paths or EPUBCheck errors, use the metadata checker guide or scan the EPUB.
Where is the file processed?
The file is uploaded to the server to read its metadata, and uploaded again when you submit changes. The temporary preview upload is removed after reading. Edit files expire after 24 hours and can be deleted sooner. Read the file-handling details.
