How to Read CHM Files on iPhone and iPad

What Are CHM Files?

CHM (Compiled HTML Help) is a file format developed by Microsoft, widely used for software documentation, eBooks, and technical manuals. Although originally designed for Windows systems, the growing popularity of mobile devices has led to an increasing demand for reading CHM files on iPhones and iPads.

Why Is Reading CHM Files on iOS Devices Challenging?

iOS and iPadOS do not natively support the CHM format, which presents several challenges for users:

1. File Format Limitations: iOS cannot recognize CHM files by default.
2. Encoding Issues: CHM files, especially those in languages like Chinese, may display garbled text.
3. Large File Handling: Some technical documents in CHM format can be quite large, making them difficult to load.
4. Navigation Challenges: Lack of effective tools for navigating directories and indexes can hinder the reading experience.
