Size Matters.

Smaller images = faster websites, especially on mobile. Your image editor won't optimize like CodeKit can.

The Best Optimizers
CodeKit uses leading optimizers like PNGQuant, Gifsicle, and SVGO, so you get the smallest possible files.
Lossless or Lossy
CodeKit does both types of optimizing; just drag the quality slider to choose. You can adjust it image-by-image if needed.
Really, REALLY Fast
CodeKit is a native Mac app, not Electron garbage. It rips through hundreds of images in just seconds and scales to use all your CPU cores.
Zero Setup
Drop a folder of images on CodeKit's window, select a few and click "Optimize". There's nothing else to install or configure.
Automatic Optimization
Optionally have CodeKit automatically optimize images as you add them to a folder so your workflow is never interrupted.
Regular Updates
CodeKit has been around since 2011, with 107 updates. You can expect new features and constant improvements.
