Assets API
On-the-fly image rendering, transformation, and delivery via CDN
The Avvyr Assets API lets you resize, crop, convert, and optimize images on-the-fly by adding query parameters to any image URL. No pre-processing, no build step — just change the URL and the CDN delivers the result.
Key capabilities
- Resize & crop — scale to exact dimensions, fit within bounds, or crop to a focal point
- Format conversion — serve WebP, AVIF, or JPEG from any source format
- Quality control — balance file size and visual fidelity per request
- Cache headers — fine-grained
Cache-Controlwith CDN-level purging - Custom domains — serve images from
images.yourdomain.com
How it works
Images are stored in cloud storage and served through a global edge CDN. When a request arrives, the rendering service applies the requested transformations, caches the result, and returns it — typically in under 50ms for cached responses.
