Many people hear the term EPS file for the first time at their printer, decal maker, or clothing supplier. It stands for Encapsulated PostScript. An EPS can be built from vector. The biggest benefit of this is that you have unlimited enlargement of the file without loss of quality. A JPG contains pixels and will loose sharpness when you enlarge it. When you UPLOAD a pixel logo, you receive an EPS and PDF file. Both are vector files your printer can work with. We create these files in Adobe Illustrator. The EPS logo you receive is the same as the PDF file.
The acronym JPG, or JPEG really, stands for Joint Photographic Experts Group. It’s a file format for compressed image material. The purpose of this is to use less space. This has benefits when loading a webpage. When you zoom in a lot on a JPG file, you start to see many pixels (squares), all with their own colour. A JPG can have the RGB (screen colours) or CMYK (printing colours) colour codes. The disadvantage of JPG compared to EPS is that the quality decreases when you enlarge them.
The term PDF is also an abbreviation, it stands for Portable Document Format and has been the standard for sharing forms and electronic documents since 1993. The format was developed by Adobe and can be opened with Acrobat Reader (https://get.adobe.com/uk/reader/). It’s frequently used in the printing world, because you can save a lot of relevant information in it, think of printing colours (even PMS, Pantone) and print profiles. A vector logo can also be saved as PDF and will come with information the designer has included (size, colour, design).
PNG stands for Portable Network Graphics. This file format was developed in 1995 to replace the GIF format. The benefit is that the background can be set to transparent, so you can place your image on different backgrounds without seeing a coloured edge, as happens with JPG. It also has a higher compression, so the edges are sharp and not grainy like a GIF file. Like JPG, PNG can store up to 16 million colours.
