Existing buckets
Use S3 or S3-compatible public object URLs as the source for product media, uploads, previews, CMS images, and galleries.
s3 image optimization
Optimize S3 images without moving your bucket
Keep product photos, avatars, screenshots, CMS media, and generated previews in Amazon S3 or S3-compatible storage. Put Skymage in front of public object URLs so templates and APIs can request exact dimensions, crops, WebP or AVIF output, compression, and cached delivery.

object storage surfaces
Start with the S3 object path your app already renders
A useful S3 image optimization test does not require a migration. Pick one public object path, one repeated surface, and one URL helper that can add Skymage parameters before the image reaches the browser.
Application helpers
Render optimized URLs from Laravel, Rails, Django, Node.js, .NET, Java, Go, or frontend response models.
No derived files
Test resize, crop, compression, WebP, and AVIF through URL parameters before adding Lambda jobs or extra object variants.
first test map
Choose one S3 image family and prove the URL pattern
The first rollout should answer whether Skymage can fetch the object URL, return the right variant, keep visual quality, and reduce transfer size on a repeated page surface.
| S3-backed surface | Skymage URL pattern |
|---|---|
| Product or listing card | ?w=520&h=390&fit=cover&f=webp&q=82 |
| Avatar or logo | ?w=96&h=96&fit=cover&f=webp |
| Dashboard preview | ?w=960&fit=inside&f=avif&q=84 |
| Gallery detail | ?w=1440&fit=inside&f=webp&q=85 |
rollout path
A low-risk S3 image CDN test
Confirm public origin fit
Use one S3 object URL or CDN-backed bucket path that Skymage can fetch consistently.
Map rendered slots
Record the real card, avatar, preview, or gallery dimensions before choosing parameters.
Change one helper
Add Skymage URL generation in one component, template helper, serializer, or API response.
Measure before expansion
Compare bytes, cache behavior, visual quality, and rollout complexity before touching more object paths.
free check
Send one S3-backed page and get the first image path to test
The free audit will identify whether your bucket URL, current template surface, and desired variants fit a low-risk Skymage rollout before adding image jobs or derived files.
