Grayscale is not a 1-bit colorspace, it is an 8-bit colorspace. If you really want black and white, you probably want it dithered. Try this: convert -monochrome -density 200 -depth 1 source.eps dest.png
Systems will still report your PNG as 8 bits per pixel; PNG doesn't have a 1-bit-per-pixel depth as I recall. TIFF does, though: $ convert -monochrome -density 200 -depth 1 logo: test.tiff $ identify test.tiff test.tiff TIFF 640x480 640x480+0+0 DirectClass 1-bit 7.74219kb On Fri, Feb 20, 2009 at 10:47 AM, Rechtsanwalt A.
