Converting JPG to WEBP is a common task when you need smaller than jpg/png at the same quality. 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. WEBP, on the other hand, gives you smaller than jpg/png at the same quality and supports transparency. ZeroUpload performs this conversion entirely inside your browser, so your JPG file is never uploaded to a server.

When should you convert JPG to WEBP?
