recently I came across this tool that might be very useful for me.
https://www.mobileread.com/forums/sh...d.php?t=252011
it handles font subsetting and image compression, without having to manually unpack/repack the epub archive. calibre can handle this as well, but this time I want smaller toolbox dedicated for the above task.
but his website is now apparently gone and he is not active in the forum for the last two years.
so I want to know if anyone who has the copy of it is willing to share. I will really appreciate it.
