Compiled HTML Help (CHM) is Microsoft’s format for software documentation and online help. A CHM packs a set of HTML pages, images, and scripts into one compressed file, along with a table of contents, an index, and a full-text search database. It was the standard help system for Windows applications for many years, and it is still used for reference manuals and technical e-books because everything ships as a single, searchable file.
How to open a CHM file?
Windows includes a built-in viewer, so double-clicking a CHM usually opens it straight away. If the pages appear blank, right-click the file, choose Properties, and click Unblock — Windows restricts help files downloaded from the internet.
On macOS and Linux, use xCHM or KchmViewer. Calibre also opens CHM files and converts them to EPUB or PDF, which is a good way to read one on a tablet or e-reader.
