ConTeXt mkiv will take an encapsulated postscript (eps) file through \externalfigure [myfigure.eps] and creates a (compressed) pdf version as m_k_i_v_myfigure.pdf that conserves the vectorial components of the eps file.
Other standard conversion tools, notably those based on ghostscript, generally create a bitmap image with pretty horrible results.
The vectorial conversion must be fully trivial, but I am ignorant of the tools available for this manipulation (other than ConTeXt!), as well as the inverse (pdf->eps) conversion. Perhaps I am simply missing some simple (ghostscript, pstoedit, ...) option.
1.) ps2pdf -dEPSCrop file.eps file.pdf
On some systems you have "epstopdf".
2.) gs -dSAFER -dBATCH -dNOPAUSE -dEPSCrop \ -sDEVICE=pdfwrite -sOutputFile=file.pdf file.ps
I use the same command for conversion into bitmap figures: gs -dSAFER -dBATCH -dNOPAUSE -dEPSCrop \ -dGraphicsAlphaBits=4 -dTextAlphaBits=4 -r500 \ -sDEVICE=pngalpha -sOutputFile=file.png file.ps
Usually the conversion from PDF to EPS is slightly problematic for (to me) unknow reason.
For pdf to eps, use pdftops from the xpdf suite (http://www.foolabs.com/xpdf/). I wrote a Ruby script epspdf with a gui Tcl/Tk wrapper epspdftk (http://tex.aanhet.net/epspdf/) for arbitrary conversions between eps, ps and pdf in any direction, with optional cropping and grayscaling. Epspdf and epspdftk are included in TeX Live. -- Siep Kroonenberg
