🔄 File Converter
Turn documents into EPUB e-books, EPUBs into Kobo-ready KEPUBs, e-books back into text, and convert images and audio between formats. Everything happens on your computer — files are never uploaded.
EPUBs built here carry your text with detected chapters — great for reading a long document on an e-reader. KEPUB is the Kobo flavor of EPUB: same book, plus the markup Kobo readers need for page stats and highlights.
The heavy lifting is done by the real converters, running in your browser: pandoc turns Word and Markdown into e-books (keeping tables, footnotes and images), and kepubify — the reference Kobo converter — makes KEPUBs. Each downloads on first use (~59 MB / ~6 MB), is cached forever, and if it can't load a quick built-in converter steps in.
