EPS What is EPS File Format

EPS (EPSF) or Encapsulated PostScript File Format is the format that is actually a PS program that describes what would a single page look like. It is actually limited PS plus particular notes that help encapsulate PostScript graphics to another document. EPS perfectly supports vector graphics or combined vector-raster graphics. The peculiarity of the format is that as soon as it is imported into a document, it cannot be edited anymore. That is one of the reasons to convert this format to the one you are able to work with.

PNG What is PNG File Format

Portable Network Graphics or PNG is one of the most popular image formats. It gives you really good compression maintaining the high level of quality of the picture. PNG is also one of the best formats for web projects, as the files are lighter and images are easy to scale. One drawback of the format when used on the web is that it is not possible to add keywords to the image directly.
