You can create smaller image files, match PNG and CSS colors, and edit more types of PNG files with the PNGOUT Plugin, a file format plug-in for Adobe® Photoshop.
- Match PNG and CSS colors by removing gamma information (the gAMA chunk)
- Read and write 8-bit Indexed Alpha PNG images (i.e., 256 colors with 256 levels of transparency/opacity)
- Create smaller files than ImageReady® (Save for Web)
- Set the background chunk for broad browser support of PNG transparency
