How to Convert CHM to PDF

At the present time, the CHM format has become widespread and is used not only for the development of documentation, but also for electronic books. Windows applications provide support for the CHM format, but unfortunately, not every application allows viewing it.

One of the solutions in this respect is conversion of the CHM files to a portable and widely recognized PDF format. PDF will allow sharing CHM files – technical documentation, e-books, manuals, etc. for those users who prefer to read texts on PDAs or smartphones as well as Macintosh computers or Linux-based PCs.
