From long, painful experience, I

From long, painful experience, I can tell you that if you’re getting a company logo made, you need to have the graphic artists send it to you in 3 formats: GIF, WMF, and EPS. Note that everything else can be converted from those (e.g., GIF->PNG, WMF->SVG, and EPS->PDF).

Many folks aren’t familiar with WMF, which stands for windows meta file. It’s a vector file format (unlike GIF and TIFF which are raster formats) and so prints out well at any resolution (curves are represented by mathematical equations rather than dots). It also does a nice screen preview (unlike EPS), and so is perfect for inserting into powerpoint and word docs.

Generally, you want to get the logo in both color and B&W versions. You might also want the original FreeHand source, in case you decide to ever do a derivative logo, but GIF, WMF, and EPS should meet all corporate needs.
