Easiest solution is GDI+: [url]http://msdn.microsoft.com/en-us/library/ms534462%28v=VS.85%29.aspx[/url] Load your bmp file into an 'Image' object then save it using the appropriate encoder: [CODE] VOID Example_SaveFile() { // Create an Image object based on a PNG file. Image image(L"Mosaic.bmp"); // Save the image. CLSID jpgClsid; GetEncoderClsid(L"image/jpeg", &jpgClsid); image.Save(L"Mosaic2.jpg", &jpgClsid, NULL); } [/CODE]

use LPCTSTR or TCHAR instead of char this will enable you to compile the same code for both unicode and multibyte. LPCTSTR maps to wchar_t or char auto depending on your build options.
