How Does Client-Side Image Compression Work?

Traditional compression tools upload your image files to their cloud servers, process them, and send them back. This uses network bandwidth and exposes your images to external servers. Our Image Compressor uses the browser-image-compression Javascript library to execute scaling algorithms directly in your browser's local sandbox memory.
