File Types Explained

  • EPS (Vector)

    vector example image

    EPS files are high-quality logo files that work best for printing. They’re scalable, meaning you can make them as large as you need without losing any quality.

    To open or use an EPS file, you’ll need professional design software like Adobe Illustrator, InDesign, or similar programs.

    EPS logos come with transparent backgrounds, which makes them easy to place over different colors or images.

    These files are the preferred choice for things like printed brochures, signs, and other high-resolution projects.

  • PNG (Raster)

    raster example image

    PNG files are best for digital use—like websites, presentations, and everyday business documents.

    They’re similar to JPEGs, but PNGs can have transparent backgrounds, which makes them more flexible for design.

    Unlike vector files, PNGs are made of pixels (also called raster or bitmap), so they can lose quality if you try to enlarge them too much.

    PNG files aren’t meant for high-quality printing, but they’re great for use in web pages, emails, and Microsoft Office applications.
