Upload your images once, get optimized variants in any size and format — directly via URL. No extra server, no complexity.
Upload PNG, JPEG, WebP, GIF or AVIF (up to 10MB) via the API or from the customer dashboard.
Append ?w=300&h=200&fit=cover&format=webp to any image and get the perfect variant instantly.
Every generated variant is automatically stripped of EXIF data — your privacy stays intact.
Each variant is generated once, then served from cache with long-lived Cache headers.
Simple and fair — per account:
✅ 1000 transformations per month — Free — the quota resets at the start of each month
🚫 Over quota: transformation is refused (403) until next month — no surprise bills
Simple REST over HTTPS. Auth: Authorization: Bearer elo_… or X-API-Key — or a logged-in session for the customer dashboard.
Honest note: transformation always strips EXIF, and animated GIFs are converted to a still frame.
