Understanding HTM and HTML file formats

Both HTM and HTML are file extensions for Hypertext Markup Language files, which are used to create web pages. The difference between them is purely in the file extension: HTM is a three-letter file extension, while HTML is a four-letter file extension. Both serve the same purpose and are used interchangeably in most cases.

Why convert HTM to HTML?

Converting HTM to HTML might be necessary for consistency, especially in environments where a standard file extension is required. Some web servers or applications might prefer one over the other, although this is rare.

How to convert HTM to HTML

Converting an HTM file to an HTML file is straightforward. You can simply rename the file extension from .htm to .html. However, if you prefer using software for batch conversion or to ensure compatibility, there are several tools available.

Best software for HTM to HTML conversion

1. Notepad++: This is a free text editor that allows you to open HTM files and save them as HTML. Simply open your HTM file in Notepad++, then go to File → Save As and change the extension to .html.

2. Microsoft Visual Studio Code: Another excellent code editor that supports a wide range of file formats. Open your HTM file, then use File → Save As to save it with an .html extension.

3. Online converters: Websites like Convertio or Zamzar offer online conversion services. Upload your HTM file and choose HTML as the output format to convert your file.
