Fast, Simple, Powerful

The best Web-based image optimizer available now augmented with advanced features.

Dedicated infrastructure at your service

Send all your images to the powerful, cutting-edge hardware powering 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.

URL Paster and Page Cruncher

Paste a list of image URLs into a simple text area and Kraken will download them all, optimize them, and give you back a ZIP archive. Enter a website URL into the Page Cruncher and Kraken 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.

Image Resizing

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. Perfect for creating thumbnails, previews and image sets to cover different devices and viewports.

16MB maximum file size

Lossily or losslessly compress larger images of up to 16MB in size. Our lossy optimization algorithms will in most cases not visibly alter your images, while shrinking their filesize by a typical 50 - 75 percent. Our lossless image optimization is perfect for situations where altering the image in any way is simply not an option. Typically, you can reduce the size of your files by up to 20% (and sometimes more) with lossless optimization. Quite impressive, considering the pixel information remains untouched.

Cloud storage

Anything and everything you optimize is instantly stored to your secure Kraken 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. It is also worth keeping in mind that we will be adding new features all the time to give you more ways to exploit this feature and the rest of the service.

Simple, flexible pricing that fits all your needs.
