Why compress images locally?

Most online image compressors upload your files to a cloud server to process them. This creates privacy risks and slows down the process with upload/download times. NanoKito Image Compressor runs entirely in your browser using WebAssembly technology.

It's faster, more secure, and works even when you're offline. Perfect for sensitive documents or high-resolution photography.
