Nothing is uploaded. Your files never leave this browser. You can even paste an image with Ctrl/Cmd+V.
Converting JPEG to WEBP is a common task when you need smaller than jpg/png at the same quality. JPEG and JPG are the same format; only the file extension differs. Older Windows software wanted three-letter extensions, so '.jpg' became common, while '.jpeg' is the original spelling. Both open identically everywhere. 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 JPEG file is never uploaded to a server.

When should you convert JPEG to WEBP?
You should convert JPEG to WEBP when you want speeding up website load times but your source is JPEG. Typical situations include renaming or normalising photo extensions, satisfying software that expects one specific spelling, where the destination expects WEBP instead.
