Optimage is an open-source image optimizer and compressor that can losslessly compress images to reduce file size. It works with JPEG, PNG, GIF, and WebP formats.
Lossless image compression software for reducing file size, supporting JPEG, PNG, GIF, and WebP formats.
What is Optimage?
Optimage is an open-source command line image optimizer that can significantly reduce the file size of JPEG, PNG, GIF and WebP images with no loss of image quality (lossless compression). It works by removing unnecessary metadata and optimizing encoding methods.
Optimage can achieve compression ratios of up to 80% for JPEG images and 60% for PNG images. It is highly configurable, allowing fine-grained control over optimization methods and effects. Key features include:
Lossless image optimization for JPEG, PNG, GIF and WebP
Stripping of unnecessary EXIF and ICC metadata
Optimization of chroma subsampling and quantization tables for JPEG
Optimization of prediction filters and compression levels for PNG
Batch processing support for optimizing multiple images
Cross-platform support for Linux, macOS and Windows
As an open-source tool under the GNU GPLv3 license, Optimage is free to use and modify. It provides an efficient way to optimize images to reduce bandwidth usage and storage requirements without affecting visual quality.
