Good to know
Your place is saved per book on this device — open the same file later to continue.
Books bought from Kindle, Kobo or Apple Books are usually DRM-protected and can’t be opened; the tool says so clearly.
For safety, any scripts inside a book are removed before it’s shown.
Questions
Why won’t my Kindle book open?
Books bought from stores are normally protected with DRM, which only the store’s own apps can open. DRM-free books (and most public-domain ones) work.
Can I convert the book to PDF?
Yes — use EPUB to PDF for EPUB files.
Are my files uploaded anywhere?
No. The file is opened and processed by your browser on your own device — nothing is sent to a server, logged or stored. You can disconnect from the internet after the page loads and the tool keeps working.
