PNG is a modern alternative to GIF and JPEG file formats. PNG supports transparency, has a better color range, and automatic gamma correction ability. PNG can even store a short text description of the image's content to help search engines categorize your images.

Image file size can disproportionally affect page load time so it's important to get it right. JPEGs are usually more SEO-friendly than PNGs, especially if you do not need transparent backgrounds, as they offer better compression levels.

A file size below 70 kb is what you should be targeting. In case of heavy files closer to 300 kb, the best you can achieve is a 100 kb file size. Doing so saves your images from taking extra milliseconds to load while it gives you lossy, compressed images that do not compromise the visual quality.

Images can be used strategically for ranking. Properly considered, images can rank in position zero. Images can also rank in image search and lead to more visitors. Images can also help search engines understand what your content is about.
