comparison checklist
Compare image CDNs by the test you can run this week
The best image CDN for an image-heavy site is the one that can prove smaller, right-sized images on one real page before you rebuild your asset workflow.
first-page test
What to compare before a migration
Transform syntax
Can one URL express width, height, crop, format, and quality without a build step?
Origin fit
Can the service sit in front of your current app, CMS, S3 bucket, Bunny Storage, or public image host?
Validation speed
Can you prove bytes and LCP move on one page within 48 hours?
Rollout risk
Can you start with one template instead of replacing every image URL at once?
decision matrix
A practical image CDN comparison table
Use this to compare any image CDN or optimization service against the specific image workflow you need to ship.
| Criterion | What to ask | Skymage fit |
|---|---|---|
| URL transformations | Can width, height, crop, format, and quality be changed through query parameters? | Built around URL-based resizing, crop, WebP/AVIF, and quality tests. |
| Existing origin support | Can it proxy current public image URLs without moving files first? | Designed to sit in front of existing app, CMS, S3, Bunny Storage, and public origins. |
| Small rollout | Can the first test be one image path or template? | The recommended rollout starts with one page type and expands only after the test wins. |
| Auditability | Can the team identify which page and image variants should change first? | Free audit and template kit focus on the first 3-5 highest-impact image fixes. |
| Developer workflow | Can developers adopt it without a new background image pipeline? | Skymage keeps the transformation contract in the image URL. |
trial plan
Run the comparison on one page
A useful comparison is not a feature spreadsheet. It is a before-and-after test on a page that matters.
02
Rewrite 2-3 image URLs
Test the above-fold image and one repeated thumbnail pattern with width, format, and quality parameters.
03
Measure the result
Compare transferred bytes, image dimensions, LCP, cache behavior, and visual quality before expanding the rollout.

Use the free audit as your comparison baseline
Send one public URL and get a practical first-pass recommendation: keep your current setup, test Skymage on one path, or postpone image CDN work until there is clearer value.
