Why it lives in the tab

WebP is the format Google built to replace JPG and PNG with a single modern alternative — and it more or less worked. Browser support is universal as of 2020, file sizes are 25–35% smaller for photographic content, and the quality at default settings is indistinguishable from JPG. The only reason not to ship WebP today is legacy client support, and that's solved with a single line of markup. We do the encode in your tab, so the JPG never leaves your machine.

Frequently asked

Why convert JPG to WebP?

WebP is more efficient at compressing photographic content than JPG. Same look, fewer bytes.

Will browsers display WebP?

Yes — every modern browser (Chrome, Firefox, Safari, Edge) handles WebP natively. Universal support since ~2020.

Is there quality loss going through two lossy codecs?

Some, but at sensible quality settings the difference is invisible to the human eye.

Lossy or lossless?

We default to lossy WebP for photos. Drop the JPG into Artboard for explicit control.

Does it work on old browsers?

Modern browsers handle WebP fine. For ancient clients, ship a JPG fallback via .
