How to convert .jpg images to .eps?

How can I convert a .jpg image to an .eps?

ImageMagick can do this.

From the commandline, simply type:

convert filename.jpg filename.eps

(On Windows you may need to put in the full path to convert.exe inside quotation marks; the above will work as-is on OS X or linux.)

It doesn't really make any sense to convert a raster graphic to a vector graphic, however. It'll still be rasterized.

Another way of doing it with a GUI would be to use Inkscape; I'm pretty sure it can import most formats, and it definitely can export to .eps — it does have some ways of trying to trace paths in a vector image to recreate the vectors, but it's far from failsafe.

Just be sure to "embed" rather than "link" when you import.

If you just want to convert an image or two to eps - use an online utility...
