Image File Guide
Selecting the right file type for the images on your site can impact the clarity of the media but also site performance which in turn impacts SEO.
When to use JPEG or PNG
JPEGs (or JPGs) work best for web photos, while PNGs might be a better choice for charts or simple graphics.
Use JPEGs for Your Media
JPEGs are used for web images because they can be compressed to much smaller file sizes than other types of image files. This makes them load faster on websites. Sites that load faster are ranked higher for SEO purposes than poorer performing sites.
Using Screenshots
Sometimes taking a screenshot of photos, for example a faculty image on another site, may actually create a larger file than actually using the original jpeg image. The default file type for most screenshot apps is PNG. PNGs are not as compressed as JPEGs, so they tend to produce larger file sizes. It is best to ask for the original JPEG file or save your screenshots as jpegs.
