About PNG
Portable Network Graphics
A lossless raster format published in 1996 as a patent-free replacement for GIF. It compresses with DEFLATE and supports full alpha transparency. Use it for screenshots, logos and graphics with sharp edges or text, where JPG compression would leave visible artifacts.
About PBM
Portable Bitmap
The 1-bit black and white member of the Netpbm family: uncompressed pixels after a short text header. Use it as monochrome input for tools such as potrace and fax or OCR utilities.
