Good to know
- The EPUB e-book is converted by calibre. Copy-protected (DRM) e-books cannot be converted: ConvertKitty does not remove DRM, so use books you have bought without it or that are free of it.
- LRF is Sony's old format: pictures are reduced and some styles are simplified.
- The LRF e-book is made by calibre from the text, headings and pictures of the EPUB file; a cover is not created.
Frequently asked questions
Is converting EPUB to LRF free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my EPUB files uploaded anywhere?
This conversion runs on our server, because reading an EPUB file needs calibre, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the EPUB file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the LRF look the same as the EPUB?
The text, chapters and pictures are kept. The look can differ: LRF readers use their own fonts and page sizes, so page breaks move.
Can I convert several EPUB files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
