Users looking for pct to jpeg conversion are actually looking for a way to convert pictures from one of the many different .pic files to standard JPEG format. This is of course doable, you just have to pick and use software that support your particular type of .pct files. Sometimes standard graphics files (JPEG, GIF, PNG etc.) have their extension just changed, so you can always try to open your .pct file directly and see if your graphics editor (even Windows Paint) does recognize it.
