What is a file extension? A file extension is a three-letter code at the end of the file name which tells your computer how to interpret it and how it was created. Some you may be familiar with include .exe, .jpg, .docx, and .txt. When is it safe to change a file extension? Though you can rename many files to switch their file extension, most will “break” when you do so. This is typically because the file type is specific to a certain code-format. In those cases you will have to use file conversion like in the case of changing SVG image files to JPG or PNG.If you just change file extensions you’ll have more luck if you change a file format to one in the same category – like changing the file extension of generic text files from .txt to .nfo, .log. However, if you turn the file extension of an image (.jpg) into a text file (.txt), you’ll just get random numbers and letters when you open it. Similarly, if you were to turn a .txt file into a .exe, nothing would happen if you tried to run it. As a result, it’s best to only change a file extension only if you have a good reason for doing so. For example, you accidentally saved it in the wrong format or the file is not working in its current form. However, you can safely experiment by creating a copy of your file and changing its file type instead of the original copy.
