HTML vs. HTM: Differences, Similarities, and Use Cases

Part 1. Understanding HTML vs. HTM

As discussed, both these file extensions play nearly similar roles in the web development to optimize the web pages. Here, we will give you a brief introduction to HTML and HTM to help you understand their functionality in a better way.

What is HTML?

When talking about this file format or extension, we can say that HyperText Markup Language is the standard language utilized to create and design documents on the World Wide Web. Moreover, this markup language uses tags to structure and format content on a web page. Apart from that, its elements serve as the building blocks of web pages, and they can include text, images, and more.

Extension: When we compare HTM versus HTML, the latter has a four letter extension compatible with modern computers. So, the “.html” extension is widely utilized to create web pages on the newer operating systems.

What is HTM?

As we compare HTM vs. HTML files, the first one is simply a shortened file extension for HTML files. Generally speaking, you can interchangeably utilize HTM with the “.html” extension, as they serve the same purpose in web development. Modern web development usually uses the “.html” extension, but “.htm” is still recognized and supported by all web servers.

Extension: Historically, the “.htm” extension was more common in earlier computing environments. When comparing HTML vs. HTM, the latter is particularly utilized in systems that restrict file extensions to three characters, including older DOS and Windows systems.

Part 2. Explore the Key Differences Between HTML vs. HTM

After getting a brief look into both these file extensions, it is time to dig deeper into the “.htm” vs. “.html” comparison. To perform a comparative analysis, you can explore this detailed table and pick the right extension for the web page development process.

Part 3. Major Similarities Between HTML and HTM

Once you analyze the HTM versus HTML debate, you can conclude that these extensions are functionally similar. The only major difference in their usage and compatibility arises due to the letters in the names of these extensions. Moving forward, we will explore the similarities between these extensions to help you understand their identical functionality in website creation.

• File Content:Both HTM and HTML files contain HyperText Markup Language code to aid during the web development tasks. Moreover, this code structures and formats web pages, which makes them readable and interactive.
• Use Cases:When talking about the purpose of these extensions, developers utilize both of them to create and design web pages and web applications. In addition, these extensions define the structure of web content and how it is displayed in the browser.
• Compatibility:If we take their compatibility into consideration, both file extensions work perfectly fine on all modern web browsers and web servers. So, developers can use them interchangeably without affecting the display or functionality of the web content.
• Development Tools:While comparing HTM vs. HTML file, you will see that these files can be created and edited using the same development tools, such as text editors and web development software. Apart from that, these tools recognize both file extensions and provide the same features for writing HTML code.

Part 4. HTM vs. HTML: Which Extension to Choose?

While choosing the suitable extension for your web development project, you need to take compatibility and certain limitations into consideration. If you are managing a website built with “.htm” extension when there was character limitation, we recommend you utilize the same extension to avoid breaking links or references within the site.

Comparing HTML vs. HTM, the first one should be your priority when handling new web development projects. When working on modern CMS or web development frameworks like React or WordPress, you should make use of the ".html" extension, as these platforms use this extension as default. All in all, we can say that HTML is preferable in modern web development due to its ability to adopt current best practices in the industry.
