GIF logo file formats are not as widely used as they once were. They have a very limited color spectrum (only 256 colors out of millions in JPG) so solid color logos are a good candidate for this format. A special feature of the GIF file is that it supports smooth animation. You can create frames with frame animations and file sizes will be negligible as long as you keep the color flat and smooth (from red to blue). GIF files are pixel-based and do not expand well.
EPS and AI logo file formats are a sacred grail of file formats. They are made up of dots and lines, not pixels, allowing infinite scaling and expansion without losing quality. Many business owners and executives ignore these logo file formats because they cannot open them normally. Many common MS Office fee programs do not open the EPS logo file format. EPS files can also support pixels, which also makes this file format difficult. Software such as Adobe Illustrator, InDesign, or Photoshop can work with this file format and optimize and save almost any logo file format you need. Illustrator will allow resizing, color mode change, and more.
PDF logo file formats can also be difficult as PDF color mode can disguise spectra and resolution. Some common office fee software will open or import PDFs but one way to tell if the resolution is good is to zoom in very closely to the logo. If the edges stay crisp, you’re in business and a graphic designer who can use something in print and digital applications. If the edges become blurred or pixelated, you will be limited in the use and extension of this particular logo file format.
SVG files have become more common on websites and digital access and are considered the standard format for displaying vector graphics on the web. SVG logo file formats allow a resizable logo format that does not lose image quality as it is expanded or reduced. This is especially important with responsive web design where the logo file can be resized depending on the digital device the website is viewing. Another major advantage for the SVG logo file format is the relatively small file size - which allows a digital file to load on a website very quickly. Support is limited to SVG but website design is an important place for their use.
