Mass Image Compressor (MIC) is a popular, open-source batch image processing utility designed to optimize, resize, and convert thousands of photos simultaneously. Developed by Cognirush Labs LLP and maintained as an AGPL v3 open-source project, it allows users to reduce large folders of heavy images by up to 90% in just a few clicks. Key Features
Massive File Size Reduction: Shrinks RAW files by up to 90%+ when converting to JPEG, and reduces PNG sizes by over 50%.
Format Conversion & Support: Supports output formats like JPEG, PNG, WebP, AVIF, and GIF. It easily reads massive digital camera formats including Canon (CR2/CR3), Sony (ARW), Nikon (NEF), Fuji (RAF), and Panasonic (RW2).
Pixel-Perfect Preview: Features a built-in split-screen comparison window, letting you inspect the original vs. compressed quality side-by-side before finalizing the batch.
Animated Image Support: Unlike basic compressors, it can resize, optimize, and convert animated GIFs and images seamlessly.
Metadata & Watermarking: Preserves crucial EXIF data and metadata for photographers while offering options to add custom watermarks in bulk. Target Audiences
Web Developers & Bloggers: Speeds up website loading times by converting images into web-friendly WebP or AVIF formats.
Photographers: Drastically reduces folder sizes for quick client delivery without sacrificing pristine image clarity.
Game Developers: Quickly optimizes massive libraries of game texture assets. How to Get It
