Can anyone convert this PDF to JPG or GIF?

Well, do you have a file size or resolution in mind?You most likely want PNG; better compression and more options than GIF, and loss-less so while the file might be bigger than a JPG there won't be any compression artifacts.

Oh, and you want it done from the EPS rather than the PDF, the PDF is made from the EPS so that's one more translation step.And do you want the whole thing or just the white square? Oops, the white square is the artboard, that seems funny. Oh well, try these 24-bit color:http://i2.photobucket.com/...F/gcrim2646x200_zps6c4e1cca.pnghttp://fleming-group.com/Misc/gcrim8192x7999.png (twice the size in both dimensions, apparently too big for Photobucket).Edited by JonF, : No reason given.Edited by JonF, : No reason given.

A lot more detail is possible, the source is a vector file with no upper limit on resolution. At some point there's no more information in higher resolutions but where that point is, is not obvious.

What do you think of the ones I posted above?

Well, there aren't all that many colors in there. Looks like seven bits is enough. So let's try it at the high resolution with 7-bit color instead of 24 bit.http://fleming-group.com/Misc/gcrim8192x7999x7.png

A WMF is smaller yet, but it may not do what you want. It's also a vector format:http://fleming-group.com/Misc/gcrim.wmf
