JPG to WebP Converter

Convert JPG photos into WebP for modern browser delivery. The result may be smaller at a similar visual quality, but the amount saved depends on the source image and encoding.

Why convert JPG to WebP?

WebP was designed as a modern alternative to JPG. It can produce a smaller file at a comparable perceived quality, although detailed or already compressed photographs may save little.

Every current browser supports WebP, so for website images there is rarely a reason to keep serving JPG. The format also supports transparency and animation, neither of which JPG can do.

Transparency: JPG has no transparency to carry over, but WebP supports it — useful if you plan to cut the subject out later without changing format again.

What you get converting JPG to WebP

Potentially smaller files

WebP can reduce transfer size, but the result depends on detail, noise and prior compression.

Useful for web delivery

A smaller image can reduce page weight when WebP produces a worthwhile saving.

Broad modern support

Current Chrome, Edge, Firefox and Safari releases support WebP; older applications may not.

Practical default

The converter uses a balanced default for photographic WebP output.

What to expect: Output size varies. Photographs with smooth areas may benefit, while detailed or already heavily compressed images can show a small saving or occasionally become larger.
