What is a CHM file?
CHM (Compiled HTML Help) is a proprietary help file format developed by Microsoft. It consists of compressed HTML documents, images, and navigation tools used to create interactive help systems for software.
CHM files are most commonly found in Windows applications and support features like full-text search, indexing, and hyperlinking. Although it’s an older format, it's still widely supported in technical documentation.
How to open CHM files
CHM files can be opened on Windows with the built-in Microsoft HTML Help Viewer. On other platforms, use CHM viewers like xCHM, KchmViewer, or Calibre.
