Non-vector (pixel) format: PNG, JPEG, BMP, P?M, GIF, TIFF, some EPS/PDF, ...

For conversions involving SVG I've already posted my solution in this
thread. For conversion between raster formats, I use convert from
ImageMagick, or the netpbm tools. For conversions involving EPS or PDF
I use ghostscript and associated tools.

Most image manipulations have a screen-capture functionality, e.g. the
GIMP. Or if your question was the following: yes, PNG will normally be
the recommended choice, unless your screen displays a photograph (but
in the latter case you probably have the image file already on your
hard drive).
