Why compress your images
Image size matters
Images that are too heavy slow down your pages, especially on mobile and over 4G. And speed directly shapes your visitors' experience and your ranking: Google favors fast sites. Lighter visuals mean better performance and better SEO.
Why WebP
The WebP format delivers quality on par with JPEG or PNG at a much smaller size. It's now one of the best-suited formats for the web: every modern browser supports it, and it often cuts a file's size in half.
How does it work?
Compression works on two fronts: quality, which simplifies the least visible details, and dimensions, which reduce the number of pixels. By adjusting these two sliders and comparing before and after, you find the right balance between sharpness and lightness.
The Vivlab tip
Resize your image before putting it online: there's no point showing a 4000 px wide photo in an area that's only 800 px. Matching the real size to the display stays the most effective way to lighten a file.
