You'll only need to use the vector EPS if a printer requests an EPS file, or if you want to make further alterations to your logo.
The vector EPS can be opened in tools like Sketch, InkScape and Adobe Illustrator and Photoshop, which your printer should already have to access your file. Most Mac's will be able to open and view these files, however if you are on a Windows computer, you will require one of the above programs to view the EPS files.
The SVG files can be used in both Sketch and Adobe Illustrator as well as GIMP. They are easily editable as they are a layered file, so if you have the design tools you can rearrange them.
SVGs can also be used on CSS enabled websites, though they have to be directly applied into the code, and cannot be added as easily as PNG files. You may require the assistance of a web developer to help you apply this change directly to your website's code.

*Note: We cannot support any issues you run into with the above editing tools. Once you've opened your logo file in the program, you may make any edits you need.
