There is no universal winner among JPEG, PNG and WebP. The right format depends on the content and where the image will be used.
JPEG: strong for photographs
JPEG is effective for photos, gradients and complex natural detail because lossy compression can remove subtle information in exchange for a much smaller file. It is less attractive for text, interface screenshots and hard edges where compression artefacts become visible.
PNG: strong for screenshots and transparency
PNG is lossless and works well for UI, diagrams, logos and text-heavy images. It also supports alpha transparency, but photographic PNG files can become very large.
WebP: useful for web delivery
WebP supports lossy and lossless compression, transparency and animation. It is often a strong web-delivery choice, although JPEG and PNG still offer excellent compatibility with older software and external workflows.
