What is the best output format for web?

Why does image compression matter?

Compression allows you to reduce the size of images on your website and reduce the total data that needs to be loaded each time a viewer visits your web pages. Therefore compressed photos can make your page speed faster, which is essential for the user's experience. Image file types for the web offer compression levels, but let’s consider which file format will allow reducing the file size while keeping its visual quality.

AVIF - offers superior compression, while keeping visual image quality, and generally has better compression than WebP, JPEG, and PNG.

Quality type:

AVIF Lossy - allows you to reduce the size of files significantly. Encoding lossy compression results in some loss of data, reducing the quality of an image. However, you can specify the amount of loss you are willing to accept with the AVIF Quality slider bar.

AVIF Lossless - file size is compressed, while the picture quality still remains the same.

However, AVIF lossless isn’t the best option when it comes to output byte sizes after compression in contrast to existing WebP and even PNG that outperformed its results.

Image Editing supports WebP lossy format for outputs set by default to quality level of 75.
WEBP - can create smaller, richer images that make the web faster. WebP lossy images are 25-34% smaller than comparable JPEG images.


If you're looking to speed up your website and make it more responsive, consider using .jpeg or .webp formats as outputs. They're typically ten or more times smaller than PNGs and load much faster.
