CHM Decoder: View and Extract CHM Files

A free, open-source tool for viewing and extracting contents of CHM files, a compressed help file format commonly used in software documentation.

What is CHM Decoder?

CHM Decoder is a free, open-source application that enables users to view and extract the contents of CHM (Compiled HTML) files on their computers. CHM files are commonly used as help documentation for software programs and contain HTML pages, images, and other files compressed into a single file.

The CHM format allows software developers to distribute help documentation as a single self-contained file that users can easily access. However, Windows does not natively support opening CHM files without additional software. CHM Decoder fills this need by decoding CHM files so users can view the HTML help pages and extract the contained files.

As an open-source program, CHM Decoder is completely free to use or modify. It provides an intuitive graphical interface for browsing and searching CHM file contents. Users can also extract individual files or the entire set of uncompressed contents for local viewing or archival purposes.

Some key features of CHM Decoder include:

  • Opens CHM help files from various software applications
  • Navigates topics and search contents
  • Extracts text, HTML pages, images, media files, etc.
  • Lightweight, safe, and easy-to-use
  • Customizable through plugin support
  • Available on Windows, Linux, and macOS

For anyone needing to access old CHM-based help files or documentation, CHM Decoder is an indispensable utility. Both average and power users will appreciate its capabilities and convenience.
