The main window of ABC Amber CHM Converter allows you to open a valid chm file and see the content, index and search tabs. You may also select from here the destination format for the output file 

Users can search a loaded .chm for custom keywords, and the program displays the result. 

The Options menu allows you to set general options as fonts and colors, pdf, HLP and LIT, Misc and CSV 

Fonts and colours for the exported file can also be changed from the options menu, as well as headers and subheaders. 

The program allows users to export custom pdfs from the selected chm and they can enter personal document information. 

Hlp & lit options provide basic Title, Copyright, Identifier and publication title options.
