Frequently Asked Questions
EPUB, MOBI, or PDF — which target?
EPUB→PDF or PDF→EPUB only — MOBI output and MOBI input are both unsupported; the tool throws for .mobi files. Newer Kindles accept EPUB directly, so convert there instead.
Do covers and metadata survive?
Only the book title carries into the new file (drawn on the PDF title line, stored in the EPUB package) — cover art, ISBN, and tables of contents do not transfer. EPUB→PDF lays out on Letter pages (612×792pt, 56pt margins, 11pt Helvetica, ~92 chars/line).
What about DRM-protected store purchases?
DRM-locked books from Kindle, Apple, or Google Play cannot convert — the encryption is the point. Convert only DRM-free books you own; strip nothing you aren't entitled to remove.
Are my ebooks uploaded anywhere?
No — conversion runs locally in your browser; your library never leaves your device. Only the final ZIP counts as one Pro download — the converted library in a single save.
