HHK2HTML

HHK2HTML is a feather-light and portable tool you can use to generate HTML webpages from HHK-formatted files. It extracts the index links from help index files compiled by Windows.
The program comes bundled with a set of approachable features that can be tackled even by those with little or no experience in HTML conversion apps.

Simple GUI for HHK conversion

The interface is clean and intuitive, made from a single window that gives you an overview of all options available. After locating and indicating the HHK file, you can set the output directory and file name of the new HTML item, as well as give it a new title.
HHK2HTML enables you to preview the generated HTML code in the main window, as well as to extract and save it to file. Moreover, you can select and copy text to the Clipboard. Once the task is completed, you can open the new HTML file to check results.
There are no other notable options provided by this piece of kit. Unfortunately, it doesn't support batch processing, which means that you cannot convert multiple HHK files at the same time to HTML format to speed up the task overall.

Portable application

Since there's no setup pack involved, you can save the downloaded .exe file to a custom directory on the disk or copy it to a USB flash drive to be able to seamlessly launch it on any PC with as little effort as possible. It doesn't have any software requirements, create files on the disk without your permission, or integrate new entries into the system registry.

Evaluation and conclusion

Conversion jobs were carried out swiftly in our evaluation, during which HHK2HTML remained light on system resources usage. On the other hand, it hasn't received updates for a long time and doesn't contain richer options for experienced users.
