Answer 1

Do you mean you want to convert the JPEG image to PNG while loading the JPEG image (and not after)?

Are you selecting and loading the JPEG image using the OpenFileDialog Class?

If yes, you can get the name of the JPEG file, pass it Image.FromFile method:
https://msdn.microsoft.com/en-us/library/system.drawing.image.fromfile.aspx
And then save it to PNG using the
Image.Save method (Stream, ImageFormat):
https://msdn.microsoft.com/en-us/library/ms142147.aspx

But if you face any problem while loading or saving the JPEG or PNG images, you can try using loading and saving features from leadtools programming toolkit.
