What buyers should know before shortlisting Kraken.io
Kraken. io compresses images through lossy and lossless algorithms.
Lossy compression reduces file size more aggressively but may introduce visible artifacts on high-detail images—test this in your demo against your actual image library. Lossless compression preserves quality but delivers smaller file size reductions.
The platform supports bulk uploads and API access, which matters if you process images programmatically. Verify integration with your CMS before purchase: WordPress and Magento plugins exist, but custom platforms may require manual API implementation.
Customer support response times have been inconsistent according to user reports—expect 24–48 hour delays during peak periods. Pricing is per-image-processed, not per-user or per-month, so calculate your monthly volume before committing.
Free tier limits exist; confirm the threshold matches your testing needs. Check whether your hosting provider blocks outbound API calls to Kraken's servers, as some managed hosts restrict third-party image processing.
In your demo, upload a representative sample of your images and compare output quality side-by-side with your current method. Ask the sales team for a cost estimate based on your actual monthly image count.
Confirm whether the integration you need (WordPress plugin, API, or manual upload) is included in your pricing tier or requires an upgrade.
