Why is the text added separately instead of painted by AI?

AI image models often misspell titles, especially in Chinese or Japanese. Typesetting your real title on top guarantees the text is exactly right in every language, and you can change it any time without paying for a new image.

Are my files uploaded?

Your EPUB never leaves your browser. For AI generation, only the style and your optional subject words are sent — never the book file or its title.

What size is the generated cover?

Covers are exported at 1600×2560 pixels (JPEG or PNG), meeting Kindle and Kobo recommendations. The AI background is painted at 2:3, the standard book cover ratio.

I already have a cover image. Can I just swap it in?

Yes — to replace a cover with an existing image, use the free EPUB cover changer instead.
