Convert PPM images to BMP format

Convert PPM to BMP

$ ppmtobmp [input.ppm] > [output.bmp]

Create Windows BMP

$ ppmtobmp -windows [input.ppm] > [output.bmp]

Create OS/2 BMP

$ ppmtobmp -os2 [input.ppm] > [output.bmp]

Force 8 bits per pixel

$ ppmtobmp -bpp 8 [input.ppm] > [output.bmp]

ppmtobmp [-windows|-os2] [-bpp n] [-mapfile file] [ppmfile]

ppmtobmp converts PPM images to BMP (Windows/OS2 bitmap) format. Part of Netpbm toolkit for image format conversion.

-windows

Produce a Microsoft Windows BMP file. This is the default (since August 2000).

-os2

Produce an OS/2 BMP file.

-bpp bits

Bits per pixel in the output: 1, 4, 8, or 24. By default ppmtobmp picks the smallest value that can represent all colors in the input.

-mapfile file

Use the given file as the BMP palette (colormap) instead of computing one automatically. Useful when you need specific palette index values.
