What is a CHM file?

CHM (Compiled HTML Help) is a help file format developed by Microsoft, widely used for software documentation, eBooks, and technical manuals. It supports indexing, searching, and navigation features, providing an efficient online help system. CHM files compile multiple HTML pages into a single compressed file, reducing file size and improving load speed. Compared to traditional HTML files, CHM offers better organization and user experience, suitable for creating complex help documents and tutorials. Additionally, CHM files often include metadata (such as title, author, chapter information, etc.), facilitating management and search. It is widely used in software development, technical support, and personal creation, suitable for user manuals, technical documents, and various types of help files.
