Documentation

Animated images support: GIFs are rescaled and transcoded to Animated WebP. Note however that it's slower and requires more bandwidth than the first frame provided by the /image endpoint.
SVG passthrough: SVGs are not rasterized by NFTCDN, which usually improves the rendering quality at the expense of versatility (cannot be used on textures or link cards for example) and security (transcoding adds a layer of security). This also requires to take care of their positioning as it can vary depending on the use or not of viewboxing inside the SVG.
The original aspect ratio of the image is preserved when ?size is used, which gives more control over the layout of image galleries, but also requires more attention.
Planned to later offer a preview of HTML NFTs using an image of the rendered HTML.
