Read blog postThe Fastest Way to Optimized Images
Transform, optimize, and deliver images in real-time via URL parameters. No preprocessing, no complexity.
From upload to optimized delivery in 3 steps
No build pipelines, no preprocessing, no configuration. Just upload your original and let the Image Proxy handle the rest.
Upload your original
Upload your full-resolution image to Fairu. We store the original safely — no quality loss, no compression at this stage.
Request via URL parameters
Add width, height, format, or quality parameters to the image URL. Each combination is generated on-the-fly and cached automatically.
Delivered optimized
The optimized variant is served instantly. Subsequent requests hit the cache — delivering in milliseconds with zero processing delay.
Simple URL Structure
Simply append parameters to the URL to transform images on-the-fly.
https://files.fairu.app/{UUID}/{filename}?width={INT}&height={INT}&focal_point={STRING}
// Example
https://files.fairu.app/9f8687a9-9a4e-4fd2-9cd8-73cc6cd51fd7/hero-image.jpg?width=800&height=600Try it yourself
Adjust the parameters and see the result in real-time. The URL updates automatically.
