Transforms

Every transform is a URL parameter. No SDK required — just append query params to your CDN URL.

https://cdn.spronta.com/{project}/{image}?w=800&h=600&fit=cover&f=webp&q=medium

Or use Cloudinary-style path segments:

https://cdn.spronta.com/{project}/w_800,h_600,fit_cover,f_webp/{image}
