IMRS

IMRS, or Image Media Reduction System, is a simple tool that runs a Cloudflare Worker that converts any image URL that's publicly accessible into a transformed AVIF & WebP version of the image, which is then stored on the Cloudflare edge for 1 year. Its goal is to save on bandwidth and improve loading times.

usage

Query parameter

Pass the image URL as a ?url= parameter.

https://imrs.danielmorrisey.com?url=https://example.com/photo.jpg

Path passthrough

Append the full URL directly after the origin.

https://imrs.danielmorrisey.com/https://example.com/photo.jpg

Format selection

Specify output format with ?type=. Defaults to AVIF; use webp for WebP.

https://imrs.danielmorrisey.com?url=https://example.com/photo.jpg&type=webp

In an HTML image tag

Wrap any src to serve AVIF automatically to supporting browsers.

<img src="https://imrs.danielmorrisey.com/?url=https://example.com/photo.jpg">

how it works

1

You pass an image URL

Either via ?url= or as a path suffix. The URL must be a publicly accessible image. Optionally specify the output format with ?type=webp (defaults to AVIF).

2

The Worker fetches and transforms it

Cloudflare's image processing pipeline converts the image to your chosen format (AVIF or WebP) at 95% quality, scaled down to fit its original dimensions.

3

You get a cached image back

The response is served with Cache-Control: immutable, max-age=31536000 — one year at the edge. Subsequent requests for the same URL are instant.
