Convert QHP to QCH

Understanding qhp and qch file formats

QHP (Qt Help Project) files are XML-based project files used by the Qt Help Framework. They define the structure, content, and metadata for help documentation, including references to HTML files, images, and keywords. QCH (Qt Compressed Help) files are the compiled, binary format of Qt help documentation. QCH files are used for distribution and integration with Qt applications, providing a compressed and indexed help system.

Why convert qhp to qch?

Converting a QHP file to a QCH file is essential for deploying help documentation with Qt applications. The QCH format is optimized for fast searching and efficient storage, making it ideal for end-user distribution.
