Kraken.io compresses and optimizes images (JPG, PNG, WebP, GIF, SVG, AVIF, HEIC, PDF) via API, web interface, WordPress plugin or Magento extension: lossy/lossless/expert compression types reducing file sizes by 50-80% on average.
Free tier with a usage quota. Paid plans from $5/month ($4.17/month annual) for the Micro tier, scaling through 6 tiers total; API sandbox access and enterprise contact for higher volume.
Developers and site owners needing programmatic, automated image optimization integrated into a CMS or build pipeline (WordPress, Magento, custom API), not merely one-off manual compression.
The API and CMS plugin integrations are the real value here over a plain web-based compressor, worth it specifically for automating optimization across an ongoing content pipeline.
Optimise your images fast, via API or a simple web interface.
