How to Optimize Images for Web Performance?

The key to successfully optimize images for web performance is to find the balance between the lowest file size and acceptable image quality. If you are able to choose the right combination to optimize images, you can reduce the size of the image up to 80%. 

Here are some of the things that can play a huge role in image optimization.

Image File Format

Most of the website owners upload images in 3 different formats i.e. JPEG, PNG and GIF. Choosing the right type of file plays an important role for optimizing images.

For the owners who want high quality images or transparent images, PNG is a good choice. However, a downside of PNG images is they are normally uncompressed and the file sizes are much larger compared to other image formats. So, it is better to edit PNG file using online tools available to lessen the image size without loosing the quality.

JPEG is for uploading images with lots of colors. Their image compressed and the quality is slightly reduced to provide significantly smaller file size.
