About Image Compressor
Image Compressor is a high-performance web utility built to compress JPEG, PNG, and WebP images. Adjust quality settings, convert formats, and scale image dimensions 100% client-side in your browser instantly and securely. Because it is designed with a local-first architecture, all processing occurs directly in your browser's memory using client-side JavaScript. This ensures that your files, code, or private text inputs are never uploaded to any external server or tracked by third-party analytics.
Whether you are formatting source code, cleaning text files, converting file structures, or running diagnostics, running these processes locally in your browser memory sandbox eliminates network latency and protects your data privacy.
