I was trying to create PDF files from photos taken with a phone camera (aka docscanner) and tried to compress as good as possible, when I realized that PNG supports 1 bit mode, with a palette of only 2 entries...
Combined with adaptive thresholding (e.g. Sauvola) this resulted in extremely compressed but still readable images.
