htm2chm

With the aid of htm2chm you can quickly compile CHM and ITS files, generate TOC and Index files, and perform other operations as well. It is backed up by a simple interface with an intuitive structure.
The main application window is clearly outdated, but its buttons provide fast access to each key feature. You can create a CHM or ITS file from a specified directory and select the preset (help, downloaded website, saved page), as well as write a title and establish the output.
Furthermore, you can generate TOC and Index files from a given location and edit existing ones, extract files from CHM/ITS files, as well as use a search function to locate and compile "saved pages". It is also possible to enable shell integration for quickly performing tasks while exploring the hard drive.
htm2chm does not put a strain on system performance, since it requires a low amount of CPU and RAM to work properly. It carries out a task in no time and doesn't trigger newer operating systems to hang, crash or show error dialogs, even though the app has not been updated for a long time.
Although the interface needs a complete makeover, users can resort to htm2chm for an easy-to-use CHM authoring application.
