Reflowable EPUB to PalmDOC MOBI Database
EPUB files package XHTML chapters and CSS inside an open ZIP container, while MOBI is a compiled Palm Database binary format. ScanPDF uses the authoritative Calibre ebook-convert engine to parse the EPUB manifest, compile reflowable chapters, and bundle images into Palm records without corrupting navigation.

Reads the EPUB spine in exact author reading sequence, ensuring multi-chapter books maintain seamless page turns on Kindle devices.

MOBI files can be copied directly over USB to your Kindle's documents/ directory for immediate offline reading on all hardware generations.
Send-to-Kindle Notice
Amazon deprecated MOBI for wireless 'Send to Kindle' delivery in favor of EPUB. MOBI is engineered specifically for direct sideloading and legacy readers.
Zero Data Retention
Uploaded EPUBs and generated MOBI binaries reside strictly in isolated temporary memory. No manuscripts are kept on the server after download.
