15 Best Image File Types (Pros vs. Cons of Each Format)

The digital world is teeming with various image file formats, each designed with a specific purpose in mind. Understanding these formats is crucial for anyone working in fields that utilize imagery, such as graphic design, web development, photography, and digital marketing. The choice of image format impacts quality, compression, and how images are handled across different platforms. In this article, we will delve into the 15 best image file types, exploring the pros and cons of each to help you make informed decisions on which format to use for your projects.

1. JPEG (Joint Photographic Experts Group)

JPEG is one of the most widely used image formats. It’s especially popular for photographs and images with gradients.
