Private by design: conversion runs entirely in your browser. No server sees your books, there's no account, no tracking, and this page is hidden from search engines.
Honest limits: browsers can't write the MOBI format, so MOBI and AZW3 are inputs only — convert them to EPUB, PDF, TXT or HTML. Files with DRM (most books bought from Amazon) can't be converted by anything on-device. PDFs carry no chapter structure, so books made from PDFs are split into page ranges. Images are dropped in conversion; the words are what travel.
