Razor and MVC views
Use one helper for Razor pages, MVC views, cards, heroes, avatars, product media, and galleries.
.net image optimization
Optimize ASP.NET images without adding image workers
Keep uploads, static files, generated previews, and object-storage media where your ASP.NET app already exposes them. Render Skymage URLs from controllers, Razor views, response models, or JSON APIs for exact dimensions, crops, WebP or AVIF output, and cached delivery.
static string SkymageUrl(string src, IDictionary parameters)
{
var query = string.Join("&", parameters.Select(pair =>
$"{pair.Key}={Uri.EscapeDataString(pair.Value)}"));
return $"https://demo.skymage.net/v1/{src}?{query}";
}
var cardImage = SkymageUrl(imagePath, new Dictionary
{
["w"] = "520",
["h"] = "390",
["fit"] = "cover",
["f"] = "webp",
["q"] = "82",
});
asp.net surfaces
Start with the controller, Razor view, or API response that already repeats image URLs
A useful .NET image optimization test starts with one public route, one uploaded or storage-backed image path, and a repeated surface where right-sized variants are easy to compare.
API-backed clients
Return optimized image URLs from C# response models or JSON APIs consumed by React, Vue, mobile, admin, or storefront clients.
Uploads and generated media
Transform public Azure Blob, S3, static file, screenshot, report, or generated preview URLs without queueing new files.
rollout path
Use URL variants before adding .NET image jobs
Pick the integration point closest to the repeated image surface, then test one controller or endpoint before changing broader media handling.
evaluation path
A practical .NET image CDN test answers four questions
Origin fit
Can Skymage transform the public upload, static, or object-storage URLs your ASP.NET app already renders or returns?
Variant control
Can controllers, Razor views, and APIs request exact dimensions instead of sending originals to every client?
Format output
Can routes ship WebP or AVIF without adding ImageSharp jobs, queues, or derived-file storage?
Rollout risk
Can one route prove bytes, cache, and visual fit before a broader media pipeline change?
free check
Get an ASP.NET image route audit
Send one public ASP.NET-backed page or endpoint. Skymage will identify the repeated image surface to test first, the URL parameters to try, and whether the current upload or static media origin fits a low-risk rollout.
