Compression service vs optimization platform
Kraken.io focuses on image compression with an API and a web interface — a dependable, narrow tool.
What Optimagio adds
Optimagio combines compression with modern-format conversion including AVIF, a static website image audit that ranks your heaviest assets and likely LCP image, resumable upload-first batches up to 50,000 files, a storage library with shareable links, verified metadata-only reports, and an explicit on-device Private Browser Mode for sensitive images.

Frequently asked questions
What is a good Kraken.io alternative?
Optimagio is a strong option if you want more than compression: AVIF/WebP output, a free website image audit, resumable 50,000-file batches, a storage library, and verified reports, all in one platform with a documented API.
Does Optimagio have an API?
Yes — a REST API with API keys, synchronous and async optimization, and upload-first batches, plus tier-based rate limits and clear error codes.
Can I optimize images privately?
Yes. Private Browser Mode processes supported images on your device with WebAssembly — nothing is uploaded and no platform result is created.
