- Different data caches: File, Distributed cache, MongoDB cache
- Image filters: resize, crop, rotate,..
- Common image effects like grayscale and blur are available
- Pdf filters: page-to-image for documents
- Url is protected by a HMACSHA256 signature to prevent DDoS attacks
- Can handle the device pixel ratio (DPR)
- Support for cache control and ETag
- Enable range processing by http request
- Use RecyclableMemoryStream for smarter memory management (IStreamPool)
Use the standalone version or middleware.
