EPUB to PDF
Drag the EPUB file, tap Shift and drop it on PDF. PlanetOS writes a PDF of the book's text that you can print, annotate or read on any device.

Drop the file on the PDF planet. The PDF copy appears next to the original a moment later.

Good to know
EPUB books reflow to fit the screen, while a PDF has fixed pages, so the page breaks in the PDF are new. Chapters, headings and paragraphs carry over.
Books bought from stores with copy protection (DRM) can't be converted; this works for DRM-free EPUBs. The same ring also offers Word, plain text, Markdown, HTML and RTF.
PlanetOS does all of this on your computer. Your files are never uploaded, and it works without an internet connection.
Questions
Can I convert PDF to EPUB too?
Yes. Drop a PDF on the EPUB planet.
Are images in the book kept?
The conversion focuses on the text, so pictures may not come across.
