And...? What have you tried? What research have you done? What language are you writing your code in? What version of .NET are you using? Where is the code that demonstrates your problem? What is the problem that you have with the code that you have written?

There is nothing in the standard Image class to handle PNG files; and I know of nothing that can handle the conversion - since JPG are full colour and PGM are greyscale, that doesn't surprise me. And given that is is an uncompressed, very basic file format, I am not surprised by the general lack of support.

So probably, you will have to write your own.
These two links should help: PGM File specification[^]

But do not expect the C# code to be a complete solution: it very definitely isn't! You are very much on your own with this one...
