For an ebook, upload an EPUB, and a PDF too if you like. Readers can download both.
For an audiobook, upload one file per chapter, or a single file. Readers can download the files or play them in their library.
Each buyer gets a marked copy
When a reader downloads an EPUB, Lanternbee adds a line to it: who bought it, from which store and on which day, with a request not to share it. This is a watermark, not DRM. The book still opens on any e-reader or app. PDFs and audio files are sent as you uploaded them.
Replacing a file
Choose Remove next to the old file, then add the new one. Readers who download after that get the new file.
