Image File Types – What’s The Best For 2021 Websites

Image File Types - Let's Break It Down

The three dominant image file types for websites have always been GIF, JPEG and PNG. This is about to change with the introduction of WebP.

One of the things that slow down websites the most is graphics. Yet these are one of the most important things to have on a site. Even with compression software, there is only so much compression that can happen resulting in a little faster but “still slow” loading website.

Image File Format 1

GIF - Graphics Interchange Format

Gifs have always been good for simple images and tiny animations. The major browsers like Chrome, Edge, Firefox, Opera, IE and Safari have always had no problem loading these.


Image File Format 2

JPEG - Joint Photographic Expert Group

Still the most popular, jpegs are the best for lossy compression. The main browsers support them.

Image File Format 3

PNG - Portable Network Graphics

PNG is a great choice for reproduction or if you need a transparent background. The browsers all support this format.

WebP - Web Picture Format

Welcome to the new kid on the block created by Google. There are many reasons why you should start converting your website images over to WebP. This image file type will be King as soon as all the browsers and image tools like Windows photo viewer begin supporting it.

Just the unique compression system can render images about two thirds the size of jpeg and png formats. This might not seem too exciting for a website with ten images on a page but image thousands of images and the speed needed to render a site that size?
