I am looking for a high-quality free JPG compression library with C# interface, as an alternative to the standard Image class of .NET.

Any suggestions?

    It is pointless to ask for a *better* one when you don't specify what kind of better you need. – Hans Passant Jan 06 '10 at 22:14
  • I am looking for a library that yields higher quality JPG compression than the standard JPG codec in .NET can provide. With all quality params maxed out, standard JPG routine lags far behind the quality of compression that we can achieve with e.g. photoshop compression. – Andy Jan 06 '10 at 22:22

Instead, describe the problem and what has been done so far to solve it.. – AStopher Nov 06 '14 at 14:30

You can try AForge but note that all JPEG operations not done with GDI+ are much slower...
