Hi,

Windows 11 / epub to kepub conversion

Since updating to Calibre 8.x from 7.x, KEPUB-output resizes the book cover to fill the device screen, rather than keep the original aspect ratio [the behaviour in version 7.x].

I know I can select “Use cover from source file” which works, but this doesn’t work with batch-conversions and [at least on my PC] the setting isn’t saved between Calibre-sessions.

Is there a workaround or would it be possible for the setting to be saved between sessions - or is this user-error on my part?

Many thanks for any assistance.
