Fast EBook Compiler produces a compressed, encrypted, and virus-protected e-book in an executable file that does not require any installation or additional viewer/reader software. It supports all the power of HTML plus such formats as DOC, RTF, TXT, PDF, CSS, GIF, JPG, BMP, PNG, MID, WAV, JavaScript, XML, DHTML, HTA, and Flash. Other features include an EBook creation step-by-step wizard, a custom splash screen displayed at the startup of an EBook, a customizable toolbar, adjustable EBook access restrictions (expiration period and/or registration key), password protection, and a lot more. Publishers can even track their EBooks' usage via the Customer Area on the developer's Web site.
