Image Optimizer

Image optimization API

Any image,
half the bytes.

One endpoint. Every transform is a query parameter, so there is nothing to upload, no SDK to install, and no storage to migrate.

Capabilities

Everything the image needs, nothing you have to build

One endpoint. Query parameters instead of a proprietary SDK.

Format conversion

Convert any image to WebP or AVIF on the fly, or omit the format entirely and let the API negotiate the best one from the request's Accept header.

  • f=avif
  • f=webp
  • Accept negotiation

Built for speed

A streaming pipeline for large images, in-memory caching, and a circuit breaker around upstream fetches.

  • immutable cache
  • streaming

Resize & fit

Width, height, and six fit strategies with position-aware cropping.

  • w
  • h
  • fit
  • position

Transforms

Quality, blur, and rotation, all expressed as query parameters.

  • q
  • blur
  • rotate

Resilient

Retries with exponential backoff keep the service healthy when origins are slow or down.

  • backoff
  • circuit breaker

Secure by default

Every request is checked before an origin is ever contacted, so the API cannot be turned into a proxy for someone else's network.

  • SSRF prevention
  • domain allowlist
  • optional API-key auth

How it works

Three steps, and none of them involve your storage

  1. 01

    Point at any public image URL

    No upload and no storage migration — the API fetches the origin image for you.

    /img/example.com/photo.jpg
  2. 02

    Add query parameters

    Width, format, quality, fit — whatever transform you need, expressed as a URL.

    ?f=avif&w=800&q=70
  3. 03

    Serve the optimized result

    Cached, retried, and served with the right Content-Type and cache headers.

    content-type: image/avif

The last row is the trade, not an oversight. Cloudinary and ImageKit are asset platforms: you move your library into them and adopt their pipeline. This is one endpoint that optimizes images already living wherever you keep them. If you need a media library, buy one of theirs.
