I have a Java website, now Ive build an uploader, the validation for JPG images is done and a way to save it into the server it is too.

But now I need to create an utility class using isGIF and isTIFF validated them by byte[] and convert that byte[] to java.awt.Image to save as JPG

So basically I need boolean isGIF(byte[]), boolean isTIFF(byte[]), java.awt.Image convertGIF(byte[]) and java.awt.Image convertTIFF(byte[]).

But I have no idea how to do it, could someone help me please?

Thank you!
