This File Guide is designed to help you decide what sort of brand asset files you should Download and Share (everyone) or Upload (Admins), depending on intended use.
With downloading naturally you're looking for a file suitable to use in whatever application you are intending to use. Generally you should have an idea of the sort of file formats, colour-space and resolution you require.
If not we hope the following will help you decide.
When uploading, you'll need to consider what Downloaders (consumers of your Assets) are going to want for their workflows at download time.
In most cases you should upload the source file, but in many cases you'll also want to consider uploading additional files that are more easily consumable generic file formats (e.g. a low res RGB .jpg for web use).
You can tell a lot about a file by it's file extension. Below is a list of common file extensions and their meaning.
This is a quick but by no means comprehensive guide as to what file types you'll(probably) need for a particular purpose.
If you're going to print something you'll need a high resolution (300dpi) raster file or a vector file. CMYK is the primary colour-space for print but SPOT colour files give better colour control, although SPOT is usually used in vector files only (e.g. logos). RGB for photos is fine also as most printers will convert the RGB to CMYK using the appropriate colour-profile at print time.
If you want something for the web, or a computer monitor - then you'll want an RGB(colour space) raster(type) file with a suitable resolution(72dip) and pixel size to suit your design. Typically JPG, PNG or GIF.
If you're a designer or and going be giving the file to a designer, you'll most likely need a source vector or raster file. Probably an Adobe Illustrator(.ai or .eps) file for vector art and a Photoshop (.psd or .eps) or TIFF(.tif) file for raster art.

Email - GIF vs JPG
For email use, GIF is best used for: ILLUSTRATIONS and line drawings such as logos, diagrams, etc, with only a few distinct colours. JPG is best used for: PHOTOGRAPHS and paintings of realistic scenes with smooth variations of tone and colour. PNG while supporting transparency, has limited compatibility in email software.
Web - GIF vs JPG vs PNG
For web use, GIF is best used for: ILLUSTRATIONS and line drawings such as logos, diagrams,etc, with only a few distinct colours. JPG is best used for: PHOTOGRAPHS and paintings of realistic scenes with smooth variations of tone and colour. PNG is best used for: PHOTOGRAPHS and paintings of realistic scenes with smooth variations of tone and colour where parts of the image require transparency.
Professional files - TIFF & Raster EPS vs Vector EPS
TIFF and Raster EPS is best used for PHOTOGRAPHIC images and paintings of realistic scenes with smooth variations of tone and colour. Vector EPS (line drawings) for logos or illustrations with only a few distinct colours.
