Technical Glossary (Series 2)

FILE FORMAT
 

JPEG/JPG - Joint Photographers' Expert Group
This format has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size.
 
PNG - Portable Network Graphics
This format is widely supported by web browsers and image viewers/editors.

BMP – BitMaP
Windows and Macintosh have their own formats, both of which are called BMP. Most modern image editing tools are able to read both.
In any case, all of the variants of BMP should be avoided when possible, as they use little to no compression and consequently have unnecessarily large file sizes.

TIFF/TIF - Tagged Image File Format
This format is used to store raw bitmap data by some programs and devices such as scanners. This format comes in a compressed and an uncompressed variant. The former is comparable to PNG, while the latter is more like BMP.
 
PDF - Adobe's PDF format (Portable Document Format)
This format is very widely used as a general purpose platform-independent document format. And while it is not exclusively used as such, it is also a very good vector image format. Those tools work with any program that is able to print.
 
EPS - Adobe's EPS format (Encapsulated PostScript)
This format is perhaps the most common vector image format. It is the standard interchange format in the print industry. It is widely supported as an export format, but due to the complexity of the full format specification, not all programs that claim to support EPS are able to import all variants of it. 

AI - Adobe Illustrator Artwork
The AI format is fairly widely supported, but is less ubiquitous than the EPS format, and most programs that read AI can also read EPS.
