What format should I use?
| CSS | SVG | PNG | JPG | |
|---|---|---|---|---|
Best for | Gradients & simple geometric shapes | Vector-based illustrations, lettering, outlined type | Simple bitmap images with few/solid colours or transparency, complex vector-based images, screenshots (with no photos) | Photographs, colourful bitmaps, rich illustrations |
Benefits | Smallest file size, no downloads, infinitely scalable | Tiny file size, infinitely scalable | Transparency, potentially small file size if optimized | Best file size and quality for photos and colourful bitmap images |
Drawbacks | Can be difficult to generate and use, limited application | Only good for flat coloured-illustrations, files with several bezier points can balloon in file size | File size can get huge if contains several colours or gradients, requires third-party optimization to get best file sizes, has to be saved double size for retina screens | Large file sizes, has to be saved double size for retina screens |
Processing tips & tools | Keep the bezier points to a minimum, size the artboard to the edges of the artwork, SVG export settings for Illustrator | Save out at double the size it will be displayed | Save out at double the size it will be displayed (2500px wide for full-width) at about 30% quality |
