On a computer, image files will have many different extensions (also known as file extensions). The file format determines the software you use to open or edit the file, and the file extension (the part after the “.”) determines the image format. When working with images, sometimes we need to convert files to a new format, so learning some ways to approach this problem is also essential! JPEG (similar to the JPG format) is a popular image extension that you’ll probably want to use.

- .jpg and .jpeg are the same format, which can be used interchangeably on modern operating systems. The difference comes from the convention on some operating systems that only allow 3 character extensions. [4] XResearch Sources

Things you need
- Image file for format conversion
- Computer
- Image editing software (Paint, Preview, Photoshop, etc.)
