The EPS file is an encapsulated postscript file type by Adobe. The purpose of this file type was to be transferable through different environments, such as between Mac and PC or from one application to another. This is also known as cross-platform compatibility. EPS is a very safe file type to use.
You’ll experience this file type a lot if you are getting stock vectors from any stock photography websites. This is great to do if you need some icons or other kinds of graphics and you don’t have the budget, time, capacity, or skill to do that. All those come in EPS format.
EPS files will natively open in Adobe Illustrator but can be opened in Adobe Photoshop and Illustrator, making them ideal for importing into computer graphics applications. When working, there may be some scenarios where you may want to save as an EPS. If you are looking at creating and selling stock illustrations, it’d be great to use an EPS file.
The advantages of EPS files are that they allow for extremely high print quality. They even beat vector graphics when it comes to high-resolution printing of illustrations. EPS allows for curved lines as well as straight lines to be re-sizable without degrading too much quality of the image. While vector graphic file formats only let images with straight lines be resized without losing quality.
The drawbacks of an EPS is that it isn’t upward scalable and that it needs Adobe to produce an image; otherwise, the image quality will be poor. As Techwalla so clearly explains, “Although EPS files are supported by most graphic design programs, page layout applications don’t usually support modification of an EPS file’s text, lines or coloration, which is another potential disadvantage of using an EPS file during production work.” This is why it is important to have your EPS file print-ready when you import it into an illustration application, as editing options are limited.
