Why this runs on your computer

There is no upload: The work happens in this tab. Your file never travels, so there is no copy of it anywhere but your own disk.
Nothing to delete later: Sites that upload promise to delete your file afterwards. That promise only matters because the file was theirs to hold.
It works with the Wi-Fi off: The honest test. Turn off your connection and the tools keep working, because everything they need is already here.

Ebook tools: read, convert and edit EPUB, Kindle files and comics

Open an ebook or a comic and read it right here, convert it to PDF, EPUB or text, or fix its cover and details. Books are personal - what you read says a lot - so none of this sends your file anywhere: it is all done in this tab.
