Good to know
- The CBZ 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.
- A comic book is a picture for each page, so the LRF holds the pictures, not text.
- 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 CBZ file; a cover is not created.
Frequently asked questions
Is converting CBZ 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 CBZ files uploaded anywhere?
This conversion runs on our server, because reading a CBZ 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 CBZ 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 CBZ?
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 CBZ 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.
