PNG is perfect for logos, screenshots and images with transparency, but its files are often heavy. WebP keeps transparency and is usually much lighter: according to Google, even in lossless mode, a WebP is about 26% smaller than a PNG. This tool uses lossy compression, which makes files lighter still.
All recent browsers display WebP: Chrome, Edge, Firefox and Safari. WordPress has also accepted it in its media library since version 5.8.
For a logo or a screenshot with text, stay around 90% to keep sharp edges. For an illustration or a photo saved as PNG, 80% is often enough. The checkerboard behind the preview shows the transparent areas.
