Pixault Documentation

Pixault is an image processing CDN and API that handles upload, storage, transformation, watermarking, and global delivery of images. Build responsive, optimized image pipelines without managing infrastructure.

What Pixault Does

Upload images via REST API or SDK
Transform on-the-fly: resize, crop, blur, watermark, format conversion
Deliver globally through edge CDN with immutable caching
Track usage with built-in bandwidth, storage, and request metering

How It Works

Your App → Upload API → Cloud Storage
                           ↓
User Request → CDN Edge → Pixault API → Transform → Cache → Respond
                  ↓
              Cache Hit → Serve instantly (zero origin traffic)

Every image is addressable by a URL that encodes the desired transformations:

https://img.pixault.io/{project}/{imageId}/{transforms}.{format}

For example:

https://img.pixault.io/myapp/img_01JK/w_800,h_600,fit_cover,q_85.webp
