When you use traditional online image tools, your personal photos, screenshots, and graphics are uploaded to remote servers. These companies may analyze your images for machine learning, store metadata, or track IP addresses. FileMint processes images entirely in your browser using HTML5 Canvas and WebAssembly—zero server uploads, zero data collection.
Our image compressor uses advanced algorithms to reduce file sizes by 50-90% while maintaining visual quality. Perfect for:
