The world of file extensions can be a complex and confusing place, especially for those who are not tech-savvy. With so many different types of files and extensions out there, it can be difficult to keep track of what each one does and how it is used. One file extension that is often misunderstood is the CHM file extension. In this article, we will take a closer look at what the CHM file extension is, how it is used, and what benefits it provides.
What Is The CHM File Extension?
The CHM file extension is a type of file that is used to store compiled HTML help files. These files are used to provide help and support documentation for software applications, websites, and other digital products. CHM files are compiled from a set of HTML files, images, and other resources, and are compressed into a single file that can be easily distributed and accessed.
CHM files were first introduced by Microsoft in the 1990s, and were widely used in the early days of the internet. They were popular because they provided a convenient way to package and distribute help documentation, and were supported by a wide range of software applications and operating systems.
How Are CHM Files Created?
CHM files are created using a process called compilation. This involves taking a set of HTML files, images, and other resources, and compressing them into a single file. The compilation process is typically done using a software tool, such as the Microsoft HTML Help Workshop.
To create a CHM file, you will need to have a set of HTML files that contain the help documentation you want to include. You will also need to have any images or other resources that you want to include in the CHM file. Once you have all of the necessary files, you can use the HTML Help Workshop to compile them into a single CHM file.
Steps to Create a CHM File
Here are the steps to create a CHM file:
- Create a set of HTML files that contain the help documentation you want to include.
- Gather any images or other resources that you want to include in the CHM file.
- Open the Microsoft HTML Help Workshop and create a new project.
- Add the HTML files and resources to the project.
- Compile the project into a CHM file.

What Is A CHM File Extension?
A CHM file extension is a type of file format used for storing and distributing compiled HTML help files. CHM stands for Compiled HTML, and it’s a proprietary format developed by Microsoft. CHM files are widely used for creating and sharing help documentation, user manuals, and guides for software applications, hardware devices, and other technical products.
CHM files contain a collection of HTML pages, images, and other multimedia content, which are compressed and compiled into a single file. This format allows for efficient storage and distribution of large amounts of documentation, making it a popular choice for software developers, technical writers, and help authors.
How Do I Open A CHM File?
To open a CHM file, you’ll need a compatible viewer or browser that supports the CHM format. Microsoft Windows comes with a built-in CHM viewer, which allows you to open and view CHM files. You can also use third-party CHM viewers, such as SumatraPDF, CHM Viewer, or Help Explorer, which offer additional features and functionality.
If you’re using a non-Windows operating system, such as macOS or Linux, you may need to use a third-party CHM viewer or convert the CHM file to a different format, such as PDF or HTML. Some popular CHM viewers for non-Windows platforms include CHM Viewer for macOS and Okular for Linux.
What Are The Benefits Of Using CHM Files?
One of the main benefits of using CHM files is their ability to store and distribute large amounts of documentation in a compact and efficient format.

Additionally, CHM files can be easily indexed and searched, making it easy for users to find specific information quickly.
Another benefit of CHM files is their ability to support multimedia content, such as images, videos, and audio files. This makes them a popular choice for creating interactive and engaging help documentation, user manuals, and guides. CHM files also support hyperlinks, which allow users to navigate easily between different topics and sections.
How Do I Create A CHM File?
To create a CHM file, you’ll need a help authoring tool or a CHM compiler. Some popular help authoring tools include MadCap Flare, Adobe FrameMaker, and RoboHelp. These tools allow you to create and edit HTML content, add multimedia files, and compile the content into a CHM file.
Alternatively, you can use a CHM compiler, such as Microsoft’s HTML Help Workshop, to create a CHM file from a collection of HTML files. This involves creating a project file, adding HTML files and other content, and compiling the project into a CHM file.
Can I Edit A CHM File?
Yes, you can edit a CHM file using a help authoring tool or a CHM decompiler. Some popular help authoring tools, such as MadCap Flare and Adobe FrameMaker, allow you to import and edit CHM files. You can also use a CHM decompiler, such as CHM Decompiler, to extract the HTML content and other files from a CHM file.
Once you’ve extracted the content, you can edit the HTML files using a text editor or an HTML editor. After making changes, you can recompile the content into a new CHM file using a CHM compiler or a help authoring tool.
Is The CHM File Format Still Supported?
Although the CHM file format is still widely used, it’s no longer actively supported by Microsoft. The last version of the HTML Help Workshop, which is the official CHM compiler, was released in 2002. However, many third-party help authoring tools and CHM viewers continue to support the CHM format.
