ImageOptim – ein kleiner Bild-„Optimierer“ für Mac

ImageOptim „optimiert“ Bilder, so daß diese weniger Platz auf der Festplatte belegen bzw die Ladezeit für Webseiten kürzer werden. Erreicht wird dies durch automatisches Einstellen der Kompressionsparameter, Entfernung von nicht notwendigen Kommentaren und Farbprofilen.

ImageOptim provides GUI for various optimisation tools: AdvPNG from AdvanceCOMP, OptiPNG, Pngcrush, JpegOptim, jpegtran from libjpeg, Gifsicle and optionally PNGOUT. It’s excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop) and also useful for making Mac and iPhone applications smaller.
