EPS (Encapsulated Postscript) files are a type of vector image file, which means they're made up of lines and curves rather than pixels. This makes them ideal for logos, illustrations and other types of graphics that need to be resized without losing quality.
If you're not familiar with vector graphics, EPS files seem like a bit of a mystery. But don't worry, we're here to help. In this blog post, we'll give you a crash course in EPS image files, including what they are, how to open them and when to use them (or not use them) in your work.

What is an EPS file?
EPS or Encapsulated Postscript files are a type of vector graphic file that uses the file extension .eps. EPS files are lossless, meaning that the file stores the information about the graphic in a way that makes it possible to enlarge or reduce the image without losing any quality. This is in contrast to a bitmap graphic such as JPEG or PNG, which is made up of a grid of tiny squares, or pixels, and becomes blurry when enlarged.
EPS files can be opened and edited in vector graphic software like Adobe Illustrator. However, due to the complex nature of EPS files, they are not as widely compatible as other image formats. You might also hear EPS files referred to as EPSF files, which is the Encapsulated PostScript Format.
EPS files are popular because they're a versatile and high-quality graphics file format. They're ideal for print logos, illustrations and other types of vector images that need to be resized without losing quality.
A brief history of EPS files
The history of EPS files goes back to the early days of desktop publishing. In those days, most graphics were created in a program called Adobe Illustrator, which used a file format called AI.
However, AI files could be quite large, and they weren't always compatible with other programs. So in 1987, Adobe introduced EPS files as a more lightweight alternative. EPS files are still based on the AI file format, but they're compressed to take up less space.
Benefits of EPS files
EPS files are scalable
The main advantage of EPS files is that they're scalable. EPS images are resolution independent, which means you can resize them without losing quality. That's because they're made up of lines and curves rather than pixels, so they can be resized without being "stretched" or "squished". This makes them ideal for print logos and illustrations, which often need to be resized for different applications. EPS files are often used for large printing projects, such as billboards.
Downsides of EPS files
EPS files can be difficult for non-professionals to edit
While EPS files have many advantages, they can also be difficult to edit. This is because they're based on a vector format, which is more complex than a bitmap format. This can make them difficult to open and edit in some programs, and they aren’t supported in Microsoft Office applications. So if you're not familiar with vector graphics, you may find it difficult to edit an EPS file.
EPS files can be large
EPS files are a type of vector file, which means they are made up of mathematical objects called vectors. This makes them ideal for printing and editing, as they can be scaled to any size without losing quality.
However, the trade-off is that EPS files can be large, sometimes much larger than raster files such as JPEGs or PNGs. This is because they contain a lot of detail, and each object in the file is stored individually. For this reason, EPS files are not always the best choice for web graphics or email attachments.
How to open, edit, and convert an EPS file
How to open an EPS file
You can open an EPS file with a range of free apps available on Microsoft Windows and Mac OS operating systems, including EPS Viewer. Even programmes that won’t allow you to edit an EPS image will often be able to display a preview image.
If you're using Adobe Photoshop, you can open EPS files directly in the program. Just go to File > Open and select the EPS file you want to open.
If you're using another image editing program like GIMP or Paint.NET, you might need to first convert the EPS file to a PNG or JPG file.
How to edit EPS files
If you want to edit an EPS file, you'll need a program that supports vector graphics. Programs like Adobe Illustrator, Inkscape, QuarkXpress, and CorelDRAW are all good options.
Open the EPS file in the program, and you'll see a screen full of lines and curves. This is the vector graphic that makes up the EPS file. You can edit this graphic however you like, adding or removing lines and curves as needed.
How to convert an EPS file
If you want to convert an EPS file to a different format, you can use a program like Adobe Photoshop or Illustrator. Just go to File > Export and select the format you want to convert to.
You can also use an online converter like Zamzar or CloudConvert to convert your EPS file. Just upload the file and select the format you want to convert it to. Then, download the converted file to your computer.
What is the difference between an EPS and an SVG file?
SVG files and EPS files are both vector graphics formats, but they have some key differences.
An SVG file is an XML-based format that allows for greater control over the graphic elements within the file. SVGs are most commonly used on web pages, and are supported by major web browsers.
An EPS file is a more simplified format that uses PostScript to describe the graphic elements. This makes EPS files less portable than SVG files. EPS files are often used in desktop publishing and graphic design, because they can contain high-resolution images and fonts. EPS files are not usually supported on web browsers.
What is the difference between an EPS and a PDF file?
EPS, or Encapsulated PostScript, is a vector-based format that is often used for illustrations and logos. One advantage of EPS files is that they can be scaled to any size without losing quality. However, they can only be opened in certain types of software, and they're not as widely compatible as PDFs.
PDF files, on the other hand, are more versatile and can be opened in most types of software. They're also smaller in size, which makes them easier to send electronically. However, PDFs are not as easily editable as EPS files, and they can't be scaled without losing quality. Ultimately, the best format for you will depend on your specific needs.
