'''PBF''' ('''Portable Bitmap Format''') was a prototype for the image format that became [[PNG]]. It was presumably never used for anything, but we document it because it appears in some lists of file formats, and to distinguish it from other formats with similar names. In particular, it should not be confused with [[Netpbm formats|PBM]].<br />
