FJCore is an image library including a pure C# implementation of the JPEG baseline and progressive codecs. Originally the library targeted Silverlight and Windows Forms applications. This is a clone of the original Google Code library that currently seems to be stagant.

Design goals

  • No external dependencies (besides a C# compiler and ECMA-standard CIL runtime)
  • High performance
  • High image quality
  • Simple, intuitive usage pattern

Portable Class Library

FJCore is now also available as a Portable Class Library (PCL) that targets:

  • Windows Store/8 apps
  • Windows Phone version 7 and higher
  • Silverlight version 4 and higher
  • .NET Framework version 4 and higher
  • XBox 360


To include FJCore in your application, we recommend NuGet.



  • Signed assemblies with snk-key to make assemblies names strong.


  • Added portable class library to solution


  • Breaking Change Changed Resize to use specific x,y dimensions and moved old Resize to ResizeToScale
