Optimage（图片压缩工具）

1、软件简介

Optimage 是一款图像图片压缩工具。Optimage Mac版是一款能够为您缩小图片尺寸，最大程度的为您节省磁盘空间的图片优化工具。
Optimage is an advanced image-optimization tool to minimize images in a visually lossless way for websites, apps, storage, and sharing. It uses advanced metrics to automatically adjust image quality for up to 10x smaller image files that are visually perceived as originals. Maximum compression ratio is achieved by exhaustively trying various compression parameters and image-data structures, using novel and traditional heuristics.
Simple native GUI and universal CLI clients are built to work efficiently across many different platforms on desktops and servers.

2、功能特色

Optimage 在减少图像内容的大小的同时，不会降低图像的质量，可以让你的图像仍然保持原有的质量。Optimage 是一种先进的图像优化工具，可以为网站，应用程序，存储和共享以视觉无损方式最小化图像。
Optimage 使用高级指标自动调整图像质量，最多可将10倍小图像文件视为原始图像文件。通过使用新颖和传统的启发式方法彻底尝试各种压缩参数和图像数据结构来实现最大压缩比。采用新颖的感知指标和改进的编码器，可将图像尺寸缩小90％，同时保持始终如一的高品质。通过使用新颖的，最先进的启发式技术来提供最高的压缩比，以实现图像缩减和数据压缩。
