Have you encountered a problem with a HTML file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a HTML file here. In the further part of this page we have added a list of programs that should open your HTML file. It is enough you choose a proper application for your operating system, download and install it.


An HTML file, often found with the extension htm, is a hypertext markup language file. Html is a text-based markup language (markup: award), which is mainly used for websites.

In addition to the actual content to be displayed on a web page, an HTML file also includes awards for how to display and structure something. For example, HTML also includes images on the website and defines which text is a link and where it should lead.

Generally you can open HTML files with any text editor, but of course you only get to see the pure source code. For better readability, one should use a text editor with programming language recognition (eg Notepad ++) or use a real web page editor. HTML files can also be opened and edited with Microsoft Word or Open Office Write, but it is not recommended.

A web browser is sufficient to display a HTML file as a web page. Embedded files, such as images, must be in the location referenced in the HTML file for correct representation. Web browsers like Mozilla Firefox or Internet Explorer also create a HTML file by saving a web page along with a folder that contains the images and other elements.

How to open a HTML file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the HTML file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a HTML file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support HTML files. At this point we are looking for disk space where the application was installed in and we can link it with a HTML file. Since then, our operating system will use the selected program to support all HTML files.

Other issues

Despite the described problem with HTML there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the HTML file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the HTML file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
