JPG to WebP converter
Convert JPG to WebP for smaller files on the modern web — locally, no upload.
Convert JPG to WebP in your browser
WebP is a modern image format that delivers the same visual quality as JPG at a noticeably smaller file size, which means faster-loading pages and lighter uploads. Converting your JPGs to WebP is one of the simplest ways to speed up a website or shrink a media library without a visible drop in quality.
This converter does the work locally in your browser using the WebP encoder your browser already ships with, so nothing is uploaded and the result is ready instantly. You choose the quality, and you can see the estimated output size before you download — handy when you are aiming for a specific page-weight budget.
WebP is supported by every current browser, so it is safe to use on the web today. Keep the original JPGs only if you must deliver to very old software that predates WebP; for everything modern — websites, apps and messaging — WebP is the smaller, sharper choice.
