Privacy-First Performance Optimization
CompressNeo was built to solve a simple problem: developers and creators need a fast, reliable, and secure way to compress and convert images without handing over sensitive data to remote servers.
Unlike traditional image compressors that upload your files to external cloud pipelines, CompressNeo operates 100% inside your browser. By leveraging modern browser APIs, multi-threaded Web Workers, and hardware acceleration, we deliver server-grade compression speeds and results directly on your CPU.
