What is Image Compressor?

Image compression reduces file size while maintaining acceptable visual quality. Our browser-based compressor uses WebAssembly and canvas APIs to process JPEG, PNG, and WebP files locally — your images never leave your device.

Smaller images mean faster page loads, better Core Web Vitals scores, and reduced bandwidth costs.
