Thumbnails and cards
Request exact square, portrait, or landscape crops for product grids, article cards, and listings.
image resize api
Resize images by URL without running image workers
Point Skymage at a public source image, then request the width, height, crop, quality, and output format each product, CMS, or app surface needs.

?w=640
&h=480
&fit=cover
&f=webp
&q=82
// Same source image, different output sizes
?w=96&h=96&fit=cover
?w=480&h=360&fit=cover
?w=1280&fit=inside&f=avif
resize targets
Use one source image across every rendered slot
A useful image resize API should make the common variants predictable: thumbnails, cards, heroes, avatars, galleries, and detail views.
Avatars and uploads
Normalize customer uploads, profile images, and workspace media without pre-processing jobs.
Hero and detail images
Serve larger AVIF or WebP variants for LCP, galleries, product pages, and editorial media.
parameters
Keep resize rules readable in the URL
Your app keeps control over dimensions and crops. Skymage handles the resize, format conversion, cache, and delivery path.
| Output | Skymage URL parameters |
|---|---|
| Avatar | ?w=96&h=96&fit=cover&f=webp&q=82 |
| Product card | ?w=520&h=390&fit=cover&f=webp&q=82 |
| Landing hero | ?w=1440&h=810&fit=cover&f=avif&q=84 |
| Gallery detail | ?w=1600&fit=inside&f=avif&q=85 |
fit check
A first resize API test should be small and measurable
Pick one source path
Start with a public upload, product image, CMS image, or avatar that repeats.
Define real sizes
Measure the rendered slots before choosing width, height, and crop parameters.
Compare outputs
Check byte savings, visual quality, dimensions, and cache behavior.
Roll out by pattern
Apply the winning URL helper to the next repeated image pattern only after proof.
free check
Find the first image resize API URL to test
Send one public page or image path. The free audit will identify the first source image, the resize parameters to try, and whether Skymage fits your current origin.
