PNGshrink

Compress PNG images with a simple drag and drop.

Simply drag your images onto the application icon to have them converted. The original image will be replaced.

Unlike other PNG compression utilities, PNGshrink (powered by OptiPNG) is a custom-built application, and does not rely on separate executables to do its work, thus improving its performance and efficiency even more.

PNGshrink requires Mac OS X Snow Leopard and is a 32/64-bit universal binary.

To do:
Currently, PNGshrink only processes one image at a time because OptiPNG was not written to work with images simultaneously. The goal is to make major changes to the library to allow for concurrent processing, which would greatly improve the performance on multi-core machines.
