EPS stands for Encapsulated Poscript and is a graphics file such as pictures, logos or photographs. It’s also for layouts of pages, maps or other types of images. The EPS file contains both bitmap and vector data for each file and uses the Postscript page description language in its internal code.
Every drawing or graphic design software can generate EPS files; layout or graphics applications like Photoshop or illustrator and some applications can save bitmap images as EPS files as well. Unlike JPG’s and PNG’s, an EPS file does not have thumbnail view so it can be hard to view it without opening.
The AI represents file format of Adobe Illustrator, a program that uses powerful vector graphics for logo creation, outlining and other types of design work. AI files are saved in vector format so they can be resized to any definition without losing quality. Some programs accept AI files but may rasterize the image and you will lose the high quality.
Vector files are composed of paths connected by points rather than the usual bitmap image data, and this high quality attribute helps to make logos of any size with perfect edge quality for print or advertising media.
A PDF document is used to present documents without a particular application to open them. PDF stands for Portable Document Format. Created by Adobe, a PDF file is designed to encapsulate a complete documentation of all the text, fonts, graphics and anything else that is needed to display it. These files can be larger than their program specific counterparts for this reason.
PDF’s are commonly used to display digital magazines, books and newsletters as all the information inside a PDF can be managed. PDF’s can be secured and even passwords protected or can require a signature to open. For this reason they can be used for important documents, invoices and legal documents.
SVG stands for Scalable Vector Graphics. Similar to AI files, these files are vector based so they can resize without losing quality. SVG’s are XML based so they can be searched, metadatet, scripted and compressed. SVG images can be created and edited with a text editor, and the files are small and compact to move or download. Usually they are opened in drawing software of some kind.
All modern web browsers support SVG to some degree and SVG commonly allow three types of graphic objects; VG, RG and text.
CDR stands for Corel Draw Vector and is a file that is associated with the program Corel Draw, a popular design program for graphic designers. The file is vector based and can be resized indefinitely without losing quality. Other programs can also open this vector graphics file including Corel Paint Shop Pro and Adobe Illustrator. The file type is not recognized by most other image editing software’s but when opened with Corel Draw it can be exported into other file types.
CAD Files may contain 2d or 3d designs and are generated by CAD software programs such as Archicad, an architect design program or other CAD programs. A CAD file, also known as Computer Aided Design file, can hold models, architecture plans, engineering designs and plans and many other types of models. 2D CAD files are known as drawings, while 3D CAD files are known as models, parts or assemblies.
DWG is a proprietary AutoCAD file format used to store two and three-dimensional design data and metadata. IntelliCAD, PowerCAD and other software support it. It has no become the base format for all CAD applications and can be viewed with free DWG TrueView program on windows. Other software’s that open this file include Autodesk, AutoCAD, SolidWorks eDrawing Viewer. This file type can also be converted with AutoDWG or Solid Converter DWG. On a Mac, DWG files can be opened with Microspot DWG viewer, IMSI TurboCAD and SolidWorks eDrawings Viewer.
CAD programs can be expensive so if you don’t have one of those then you can still view DWG files after converting them to PDF, TIFF, or JPG with Total Cad Converter.
DXF stands for Drawing eXchange Format and is an AutoCAD file type. This file type is for a graphic image typically created by AutoCAD. Depending on the software used, this file type can be saved in ASCII or binary format. There have been many changes to this file type over the years, and it enables high quality data transfer between AutoCAD and other programs.
JPG or JPEG stands for Joint Photographic Experts Group. These files are most commonly used for photographs, specifically digital photographs created by digital cameras. It’s commonly used for maximum image quality with a high compression rate for creation of smaller files. The degree of compression can be adjusted in most graphic design software’s allowing for a selectable tradeoff between storage size and image quality. JPG and JPEG is the most common image format used by digital cameras, as is the most common format for storing and sharing images on the Internet. At it’s best the compression algorithm displays paintings and realistic scenes with high color quality and striking tone. Online where web masters track the amount of data used meticulously, JPG’s are very popular.
JPG’s may not be great for line drawings like logos or textual graphics where sharp contrasts will start to blur and the quality compromise is not worth it for displaying a high quality image.
PNG stands for Portable Network Graphics, and is pronounced ‘ping’. This is a raster graphics file format that supports compression without a loss of data. PNG’s were created as an improved replacement for GIF’s and is the most commonly used lossless image compression on the Internet.
PNG’s allow transparency in their images so backgrounds of webpages will be seen behind the image instead of a square white box as is usually seen with typical JPEG images on the web. PNG’s are single image formats and cannot display animation like GIF’s can.
