Kraken – Fast & Online Image Optimizer

Minimizing the size of images is an important part of the process for creating faster loading web pages.

We usually play with various variables while saving images to make sure they are optimized like the colors used, file type or quality but there can still be some bytes hidden.

Kraken, a free to use web application, finds those bytes and optimizes the images with a user-friendly interface.

It has support for adding multiple images (up to 20, max 1mb each) via drag 'n' drops, selecting from disk or getting from a URL and quickly uploads + optimizes them.

P.S. The application accepts .JPEG and .PNG files

    Hmm …

    Does what SmushIt does through Firebug without the useful interface and seems to be worse at compressing .png

    I am going to stick with Firebug addon.

    @Giles Marshall:
    You are so wrong. As I can see, beats in terms of optimization level as well as time needed for optimization for EVERY single png image.

    I am going to choose :]

  • Serg beats both and

    Logo of this site: logo-small-trans.png – 14585 bytes – 12747 bytes – 12371 bytes, indexed – 7396 bytes, indexed – 7031 bytes

    But allows to reduce the number of colors manually. For that image 32 is more than enough., indexed, 32 colors – 2987 bytes
    No visible difference.
