 .AI (Adobe® Illustrator™)
AI is an Adobe Illustrator file, one of the most widely used graphic design programs in the world. Usually a file with the tag AI is an original design file, meaning that this is the file originally used for developing your logo design. AI files can generally only be opened successfully using the Adobe Illustrator program and cannot be generally brought into other applications.
.EPS vector files
EPS stands for Encapsulated PostScript. It can contain both vector and bitmap data. PostScript is the universal language used by computer printers as well as professional printers. If the file contains only vectors it can easily be reduced or enlarged without loss of resolution and is the best file to give to a professional printer for reproducing your logo on the printed page.
.SVG vector files
Adobe® describes SVG as the "next generation of data-driven, interactive, and personalized graphics on the web" SVGZ is the compressed version.
.CDR (Corel Draw)
A CDR generally can only be successfully opened in the Corel Draw suite of applications. CDR is favoured by signmakers and embroidery stitchers.

 .JPEG raster files
This graphics file is compressed and can open into almost any other application. JPG files are typically used for on-screen purposes such as on Web sites or within email messages; this is because the files are small. They are not ideal for printing and cannot be resized or edited too often without significant loss of image quality.
.GIF raster files
These are used in the same way as JPG files but are compressed even more, making them ideal for graphics with solid colour; because of their high compression, these files should not technically be used for graphics with gradients (such as photographs).
.TIFF raster files
TIFF stands for Tagged Image File Format. This type of graphics file can also be compressed, meaning that it has been calculated down to contain only vital information. Like an EPS file, a TIFF file can also be moved into almost any other application. However, a TIFF file cannot be enlarged without loss of resolution; it can only be reduced. |
Software vectoring is often used to "capture" an image into a vector format. Color photo's and at the other end pure black and white convert well.

Hand vectoring is the prefered method of conversion for most artwork especialy logos and icons. Below is a logo in the process of hand vectoring.
