Why local image processing?
Most online image compressors upload your files to a server, process them, and send them back. That means waiting for two transfers, trusting a stranger's storage with your photos, and often hitting file-size limits. BasaltKit's image compressor uses the Canvas API inside your browser: files never leave your device, there is no upload limit, and results appear instantly — even offline.
