PIG is an obsolete format associated with Ricoh's Pixel Image Generator (IS30). Ricoh is a Japanese manufacturer of printers, cameras, photocopiers, fax machines and other types of electronics equipment, and the PIG extension is attached to images created by software included in such devices. PIG images are rare and opening them using regular image viewers might be difficult.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple PIG files as once.
