Converting JPG to JPEG is a common task when you need identical to jpg. JPG (also written JPEG) is a lossy compressed format engineered for photographs. It discards detail the eye barely notices to produce far smaller files, and it is the most universally supported image format in existence. JPEG, on the other hand, gives you identical to jpg and small files. ZeroUpload performs this conversion entirely inside your browser, so your JPG file is never uploaded to a server.
