ChmBatchDecompiler

ChmBatchDecompiler is a simple-to-use and portable software application that enables you to decompile HTML help files (CHM format) in batch mode, as the name implies. It does not include complex options or configuration parameters, making it accessible to all types of users, regardless of their level of experience.

Portability advantages

Since there is no installation involved, you can drop the executable file in any part of the HDD and just click it to run, as well as save it on a USB flash disk or other removable storage unit, in order to run it on any PC effortlessly and without previously installing anything.
An important aspect to take into account is that the tool does not modify Windows registry settings or create extra files on the HDD without your consent, leaving no traces behind after its removal.

Simple interface and options

The GUI is based on a single window with a plain and simple structure, where you can point out entire directories whose CHM files you want to decompile; the tool takes into account only the supported file types, so it does not matter if the folder also contains other file formats as well.
It is possible to include subfolders and indicate the target directory before starting the decompiling procedure with the click of a button. There are no other notable options provided by this software utility. The main window shows the status of each processed file, and the saving directory contains a folder corresponding to each CHM file, which contains the decompiled files.

Evaluation and conclusion

The tool does not put a strain on PC performance, as it runs on low CPU and memory. We have not come across any issues throughout our evaluation, since it did not hang, crash or pop up error messages. All in all, ChmBatchDecompiler gets the job done and can be handled by anyone.
