CHM Converter
CHM (Compiled HTML Help) is Microsoft's format for help documentation and technical manuals. If you've ever pressed F1 in Windows software and seen a help window pop up, you were probably looking at a CHM file. The format packages HTML pages, images, and navigation into a single compressed file. Popular in the late 90s and 2000s for software documentation, CHM files include full-text search, table of contents, index, and hyperlinks between topics. While Microsoft has moved toward online documentation, you'll still find CHM files for older software, technical references, and ebook collections - especially technical books and programming references that were distributed in this format. CHM files work natively on Windows but require special software on Mac and Linux. Converting CHM to more modern formats like EPUB or PDF makes the content accessible on any device while preserving the documentation structure, navigation, and searchability.
