Convert EPUB ebooks to paginated PDF, or PDF ebooks back to EPUB — real local text extraction. MOBI/Kindle files are rejected (repack them to EPUB in Calibre first); images-only books need OCR.

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.
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).
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.
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.
