Convert any PDF to a valid EPUB file you can read on Kindle, Apple Books, Kobo, and other e-readers. 100% client-side.
How it works: Text is extracted from the PDF using pdf.js, then packaged into a standards-compliant EPUB 3.0 file using JSZip. Images embedded in the PDF are not transferred — this works best with text-heavy documents. For image-heavy PDFs, consider using the PDF Reader tool instead.
