What Squoosh is
Squoosh is a free web app for compressing images. It offers multiple formats and both compression modes, and lets you open an image, compare the original with the result, adjust settings, then save the compressed file. Squoosh says it can reduce file size while maintaining high quality. Processing happens locally, so images do not leave the device, according to the app. The workflow is aimed at people who want to compress a single image, inspect the change, and save it. The project is open source under an Apache-2.0 license. Its README says Google Analytics collects basic visitor data and before-and-after image size values; for PWA installations, it also collects installation type and date and time. Squoosh runs on the web and has no batch processing or API access. The free plan costs nothing.
