WebP already compresses better than JPG or PNG at the same quality — this tool tightens it further toward an exact target size, while keeping transparency if your image has it.

We search for the highest WebP quality that fits your target, and only shrink dimensions if that's genuinely not enough.
WebP supports both lossy and lossless compression plus transparency in one format, typically producing 25–35% smaller files than JPG at similar visual quality. Nearly every modern browser supports it.
A handful of older tools and some print or email workflows still don't accept WebP. If you're not sure the destination supports it, our WebP to JPG converter is one click away.
WebP encoding relies on your browser's built-in support. All current versions of Chrome, Edge, Firefox, and Safari support it — if yours doesn't, we'll tell you clearly instead of failing silently.
