TIFF *using CCITT G4 compression* almost always gives much better compression
than GIF. G4 TIFF is more or less a standard in the document imaging world.

For Windows users, the Imaging program which comes with Win 95 & NT 4.0
understands G4 TIFF files. There are free programs on most/all other platforms
too (even my Amiga).


There are other lossless image formats which have even better compression (i.e.
JBIG), but they are not as widely used yet.
