OptiPNG 0.6.4 (PNG Optimizer)

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.
If you wish to learn how PNG optimization is done, or to know about other similar tools, read the PNG-Tech article A guide to PNG optimization.
