File Types – JPG / GIF / TIFF / EPS

Monday, May 23rd, 2011

Many of us would consider ourselves tech-savvy; we have the internet at our disposal and we know the functions of Microsoft Word and Excel like the back of our hand. We know how to add on animations to our presentations so that it appears more interactive, and pictures and graphics to help enhance the reader’s understanding. Given the different file types available for use, it is easy to confuse them and end up using what is available, and not what best suits your needs.

Design Workz would like to delve a little deeper into the various file types available, so that one and all will no longer mix them up.

Firstly, we have JPG files. JPG files are also more commonly known as JPEG files, short for Joint Photographic Experts Group. As evidenced from its name, this file type is most suitable for digital photos and graphics, as it can support up to 16.7 million colours. This file type is used widely across many web-based applications due to its high downloading speed. When JPG files are compressed, the image quality is also lost as file size decreased.

Next, there are GIF files. GIF stands for Graphic Interchange Format. It is also the most common file type for graphics used on websites, as GIFs can contain up to 256 colours, and are best for images that are made up of simple shapes, or if animation is required. Another benefit of this type of file is that it supports transparency, which is ideal for graphic designer’s usage.

TIFF files refer to Tagged Image File Format, ideal for master copy imagery and usually unsuitable for web based applications due to their large size. TIFF files are good for desktop publishing, as it supports up to 16bit per channel. Known for its flexibility and multiple colour depths, this file format is hugely used by scanners and fax machines. Based on a Windows preview, the most supported file type is the TIFF.

EPS files translate to Encapsulated PostScript files, and it can contain any combination of graphics, text or images. Suffice to say, it also one of the most versatile file types. It also supports an unlimited number of colours, and files with this format frequently a preview picture of the content for on screen display. An application which is unable to interpret an EPS file will usually show an empty box on screen, but will still be able to print the file correctly. However, EPS files are slowly becoming obsolete, and are being replaced by PDF file formats.

Design Workz hopes that this brief introduction to file formats will give you an idea of which format would suit your type of work best, and aid you in making the correct choice.
