Convert to WebP
Add a JPG image to enable conversion.
Convert JPG to WebP free in your browser to make your photos noticeably smaller. WebP is a modern image format that typically produces files 25–35% smaller than an equivalent JPG at similar quality, which means faster page loads and less bandwidth.
WebP is supported by all current browsers, so it's a great default for the web. The conversion happens entirely on your device using the Canvas API — your image is never uploaded — and you can download the optimised WebP straight away.
