Best Image Format for the Web
Pick an image format that balances quality, transparency, compatibility and page speed.
The short answer
WebP is a strong general default for modern websites. JPEG remains useful for photographic compatibility, while PNG belongs where lossless rendering or transparency is essential. SVG is preferable for code-native logos and simple illustrations, though it is not a photo format.
A quality-first workflow
The best choice also depends on delivery. Declare image dimensions to prevent layout shift, provide responsive sizes, and avoid sending desktop-size assets to small screens.
Why this matters
Image dimensions, file size, format, and compression settings all affect upload success, page speed, and visible quality. The right workflow starts with the actual requirement, then changes only what is needed.
