Convert images to WebP
Turn your JPGs and PNGs into WebP, the format that weighs half as much at the same quality and that every current browser understands. It exports to AVIF too if you want to squeeze further.
How to convert to WebP in 3 steps
Drag in your JPGs or PNGs, the whole batch if you need to.
Pick WebP (or AVIF) and set the quality wherever suits you.
Take the ZIP with every photo already converted and renamed.
Why WebP is worth it
Frequently asked questions
What is WebP and why use it?
It is an image format designed for the web: it reaches the same visual quality as a JPG in about half the space, and it supports transparency. Less weight means pages that load sooner and better rankings.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Safari and mobile browsers have read it for years. Only very old versions that almost nobody runs are left out.
Do I lose transparency when converting a PNG?
No. WebP keeps transparency just like PNG and usually weighs far less. The one that does not keep it is JPG, which fills the background with white.
Can I convert many images at once?
Yes: drag in the whole batch, pick WebP and download everything as a ZIP. You can rename the series with a pattern along the way.
