The whole pipeline.

Upload to delivery — nothing skipped, nothing to configure.

The browser uploads straight to the CDN. Your server never sees the file.

  • Presigned URL — client talks to R2, not you
  • No bandwidth cost, no timeout risk
  • S3-compatible, works with any SDK
// Get a presigned URL (server-side)
const { uploadUrl, imageId } = await
spronta.images.createUpload({ folder: "products" })
// Client uploads directly — no proxy
await fetch(uploadUrl, {
method: "PUT",
body: file,
});
// Image live at:
cdn.spronta.com/{projectId}/{imageId}

A few lines of code.
That's it.

Upload images with presigned URLs, transform them with query parameters, and deliver via our global CDN. No complex configuration.

  • Direct client uploads via presigned URLs
  • URL-based transforms — no build step
  • S3-compatible — zero vendor lock-in
  • TypeScript SDK with full type safety
upload.ts
import { Spronta } from "@spronta/sdk";

const spronta = new Spronta("sk_live_...");

// Get a presigned upload URL
const { uploadUrl, imageId } = await
  spronta.images.createUpload({
    folder: "products",
  });

// Upload directly from the client
await fetch(uploadUrl, {
  method: "PUT",
  body: file,
});
