Privacy

How “nothing is uploaded” is enforced

Many converters say your files are private and then delete them from a server later. This one never sends them to a server in the first place. This page explains what that means and how you can check it.

The short version

  • Every conversion happens in your browser, and your browser saves the result.
  • Nothing on this site uploads files or sends forms anywhere.
  • We do not receive or store any file name, title, author or other book detail. Closing the tab clears everything.
  • Nothing is remembered between visits. There are no accounts, no logins and no cookies from us.

Checking it yourself

In your browser

Open your browser's developer tools, go to the network panel and convert a book. You will see the page load, and then no request carrying your file.

You can also convert with your internet turned off. After the page has loaded, everything works offline except the first load of the PDF tool.

In the browser's rules

Every page tells your browser not to connect to any other site, not to send forms and not to let another site embed this one. So your browser itself would block an attempt to send a book anywhere.

Untrusted books

A book is a file someone else made. Before we show one, we remove anything in it that could run code, and we keep it walled off from the rest of the page. We also clean up file names inside a book so it cannot save files to unexpected places.

What is measured

We count page views with privacy-friendly analytics: which page was visited and where the visit came from. Analytics cannot see the books you open, because they never leave the tab.

There is no cross-site tracking, no advertising and no fingerprinting.

And on DRM

Copy-protected (DRM) books are detected and refused with a plain explanation. This site does not remove DRM and will not. The formats page explains how each kind of protection is recognised.
