Where Power and Simplicity Collide
The best image optimization SaaS available now augmented with advanced features.
The Most Reliable Image Optimization API
Kraken.io API handles millions of requests per day without a hitch. That is because we have engineered reliability and performance at all levels of the stack - and we never stop looking for ways to improve. At Kraken.io, we take immense pride in our engineering practices, incorporating both advanced system monitoring and QoS monitoring.
Dedicated Infrastructure at Your Service
Send all your images to the powerful, cutting-edge hardware powering Kraken.io and get them optimized in no time. We selected dedicated hardware specifically for the resource-hungry task of image optimization, so optimizing all your images will not consume a single CPU cycle on your own machines. Just send your images to us, we’ll do the work. It’s that simple.
Web Interface PRO
Paste a list of image URLs into a simple text area and Kraken.io will download them all, optimize them, and give you back a ZIP archive. Enter a website URL into the Page Cruncher and Kraken.io will grab all the images it finds there, including background images from CSS, optimize them, and give you back a ZIP archive. If you like, you can have the images placed into a folder structure matching that of each image URL. Quick, simple and fun.
Many images are larger, in terms of dimensions, than they need to be for a given use-case or purpose. When you need to generate sets of images in different sizes or dimensions, our easy-to-use image resizing interface has you covered. Just specify your required dimensions and pick one of several strategies for resizing your images, prior to optimization.
Kraken.io ZIP Uploader
Upload a ZIP archive by dragging it into our Web Interface. Kraken.io will decompress it, optimize all images found within the archive and notify you once the job has completed. A huge convenience if you have a large number of images to optimize in one go, or if you want to keep your folder structure intact. You can even close your browser window and come back later to download the processed ZIP archive.
No Vendor Lock-In
Using a CDN? Kraken.io does not force you to use any particular vendor, giving you the freedom to change your CDN provider whenever you like. Kraken.io even supports pushing optimized images to your favourite Cloud Storage provider like AWS S3, Rackspace CloudFiles, Microsoft Azure and SoftLayer, allowing for even greater flexibility in managing your assets.
Event Callbacks via Webhooks
Do you prefer service providers which support HTTP callbacks? So do we, and so we built a world-class webhook delivery system. Kraken.io supports simple event-notifications via HTTP POST whenever something happens, such as completion of an optimization. Use Kraken.io webhooks to notify your app of when a process has completed, rather than keeping numerous connections open simultaneously.
Kraken.io Cloud Storage
Anything and everything you optimize is instantly stored in your secure Kraken.io Account, for easy access, anytime, any place. Our sleek and easy-to-use interface lets you manage your images with ease, and there is no upper limit to how much you can keep in your account. We'll even store the optimized ZIP archives you have uploaded through our Web Interface.

We'll do our best to help even if the problem lies somewhere on your system. We're here to help you get the job done and ensure smooth operation between systems, around the clock.
