Before you export
EPUB is a collection of publication files inside a ZIP package. Metadata lives in the OPF package document, while book covers are linked from the package manifest.
This editor does not remove DRM, decrypt books, update embedded cover pages, or make textual edits to chapters. Some storefronts may keep their own metadata separately.
Frequently asked questions
Does PixelOkay upload my EPUB file?
No. The EPUB is read and processed in your browser. The only external links on this page are optional links to standards documentation.
Can I edit a book with DRM?
No. This tool rejects EPUB archives with encryption metadata because modified package identifiers or resources could break font obfuscation or protected content. It also rejects digitally signed publications.
Will the cover change inside the first chapter too?
Not necessarily. When the EPUB has a valid PNG or JPEG package cover, the editor preserves its file path and converts the replacement to the original image type if necessary. This keeps embedded cover-page references intact, but JPEG conversion can be lossy and transparency may be flattened. If no compatible original cover exists, a new package cover is added and embedded XHTML cover pages are not rewritten.
What formats work?
Standard EPUB 2 and EPUB 3 files with one package document, an unencrypted ZIP archive and valid OPF XML. Cover replacements must be JPEG or PNG.
