What is a .HTM file?

htm file icon

HTM files are used on the Internet to store HTML, which stands for "Hypertext Markup Language." The files contain tags that define the structure and content of webpages displayed in web browsers. They serve the same purpose as HTML files but are an alternative for servers that do not support four character extensions.

HTM files are typically created and edited by web developers, although the files are not as common as HTML files. If you are not a developer, you most likely will only encounter an HTM file if you download a webpage from a web browser. You can use File Viewer Plus to view the HTML in an HTM file as a webpage or as source code. When viewing the source code, the program provides various viewing features, including a syntax tree view, word wrap, code folding, ruler, and line numbers. File Viewer Plus also allows you to edit the HTML in the file and save your changes in an HTML file.

Batch Convert

When viewing an HTM file as a webpage, it may not appear the same as in a web browser. If you edit the source code, you can save the result as an HTML file.
