What Is an EPS File?

How to open, edit, and convert EPS files

A file with the EPS file extension is an Encapsulated PostScript file. They're typically used by drawing applications to describe how to produce images, drawings or layouts. EPS files can contain both text and graphics to describe how the vector image is drawn, but they also usually include a bitmap preview image "encapsulated" inside.

EPS is what early versions of the AI format was based on. Encapsulated PostScript files may also use the .EPSF or .EPSI file extension.

How to Open an EPS File

Open or edit EPS files with vector-based image editing applications. Other programs most likely rasterize, or flatten the EPS file upon opening, which renders any vector information uneditable. However, like all images, EPS files can always be cropped, rotated and resized.

EPS Viewer, Adobe Reader, and IrfanView offer fast and effective tools for opening and resizing EPS files on a Windows PC. You can also view EPS files in Windows, Linux, or macOS if you open them in OpenOffice Draw, LibreOffice Draw, GIMP, XnView MP, Okular, or Scribus.

Ghostscript and Evince work for either Windows or Linux, while Apple Preview, QuarkXpress, and Design Science MathType are EPS openers for Mac, specifically.

To avoid having to download a program to use the EPS file, Google Drive functions as an online EPS viewer because it works entirely online through your browser.

Adobe Photoshop, Adobe Illustrator, Affinity Designer, and Microsoft Word (through the Insert menu) also support EPS files but they aren't free to use.

If the "wrong" program on your PC tries to open EPS files, change the default program for that file extension.

How to Convert an EPS File

One easy way to convert an EPS file is to use Zamzar. It's a free file converter that runs in your browser to convert EPS to JPG, PNG, PDF, SVG, and various other formats. FileZigZag is similar but converts the EPS file to document file types like PPT, HTML, ODG, etc.

EPS Viewer converts EPS to JPG, BMP, PNG, GIF, and TIFF. Adobe Photoshop and Illustrator can convert an open EPS file through their File > Save As menus.

Is Your File Still Not Opening?

Verify that the file you're using really is an Encapsulated PostScript file. Sometimes file extensions are typed incorrectly, so what you think is an EPS file might be something else entirely.

For example, ESP looks very similar to EPS but is instead the suffix used for plugins in The Elder Scrolls and Fallout video games. You'll most likely get an error if you try opening an ESP file with the EPS openers and editors from above.

EPP files are similar and are associated with several file formats, but none of them are related to an Encapsulated PostScript file.
