Why convert PGM to BMP?

Limits
Starting point: PGM - PGM is the Netpbm grayscale format storing one sample per pixel. Color data collapses to gray on import, which cannot be undone. Uncompressed files run large; prefer PNG for the same pixels. Export BMP from PGM at matched dimensions; every pixel maps across, so large sources stay large.
