Origin fit
Use current public image URLs instead of moving files before you know the output works.
image optimization tool
Test image optimization on one URL before changing your media stack
Skymage gives teams a practical image optimization tool: request exact width, height, crop, quality, WebP or AVIF output, and cached delivery from the image URLs they already use.
Tool fit test:
1. Pick one current image URL
https://assets.example.com/uploads/hero.jpg
2. Build one optimized variant
?w=1280&h=720&fit=cover&f=avif&q=82
3. Compare
rendered dimensions
transfer size
visual quality
cache behavior
what it should do
Evaluate image optimization tools by the first useful output
A useful tool should turn one existing image into a smaller, correct, repeatable URL before you commit to a broader image workflow change.
Right size
Set dimensions and crop behavior for the rendered slot, not the uploaded original.
Format and quality
Compare WebP or AVIF with quality settings that match each surface.
Reusable URL
Keep optimization choices explicit so templates and components can repeat them.
comparison lens
Compare tools against the image slots users actually load
Start with visible images and repeated templates. If the tool cannot prove smaller bytes, correct dimensions, and acceptable quality there, the broader migration is premature.
| Test surface | Skymage URL target |
|---|---|
| Website hero | ?w=1440&h=810&fit=cover&f=avif&q=84 |
| Product card | ?w=520&h=650&fit=cover&f=webp&q=82 |
| CMS article card | ?w=480&h=270&fit=cover&f=webp&q=80 |
| Avatar or thumbnail | ?w=96&h=96&fit=cover&f=webp&q=78 |
audit output
What the free image optimization tool audit returns
First image candidate
The public image URL most worth testing before broader rollout.
Variant settings
Width, height, fit, format, and quality parameters for the first test.
Evidence checklist
What to compare: bytes, dimensions, quality, cache behavior, and rollout fit.
Next template
Where to apply the same pattern if the first URL passes review.
free check
Send one URL to test the image optimization tool fit
Share a public page or image path. The audit will identify one optimized Skymage URL pattern and what to compare before changing more templates.
