Convert JPG to WebP Online
Shrink JPEG product photos into smaller WebP files for faster-loading listings — free, in your browser, with nothing uploaded.
JPG vs WebP for product photos
JPEG is the universal format for photos and works on every marketplace, but it isn't the most efficient. WebP delivers the same quality in a noticeably smaller file — typically 25–35% less — which adds up fast across a catalog of product images.
A common seller workflow: keep JPG for marketplace uploads that require it, and serve WebP on your own Shopify or custom storefront for speed.
How to convert JPG to WebP
- Open the image format converter.
- Drop in your JPG / JPEG photo.
- Choose WebP as the output format.
- Click Convert and download the smaller file.
