Traditional cloud-based compression websites require you to upload your gigabytes of raw photos over your internet connection, wait in a server queue, and download them back.
With PixEnhance, the compression engine runs directly on your computer hardware via modern browser APIs. It is instantaneous, completely private, and works even when your internet connection is slow.
