Coolmuster SignPub 2.1.15
As we know, ePub is reflowable, which means it can be adapted to different devices as need. But, for more modifications of the ePub files, a helpful ePub editing software is undoubtedly a necessity. Coolmuster ePub Editor comes here to meet your needs. SignPub does what it is supposed to do. I have used it for several times and I'm quite satisfied with its functions. I often edit the images, change covers and modify the fonts in my ePub files, and the effect is really excellent! Pretty worth a try!
