What Squoosh is
Squoosh is a free web app for compressing images in a range of formats. Open an image, adjust compression settings, inspect the result alongside the original, and save the output. Squoosh says it can reduce file size while maintaining high quality, and that image processing takes place locally so images stay on the device. 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 installation date and time. Squoosh supports both compression modes, but its workflow is for one image at a time: batch processing and API access are not available. It runs on the web. The Free plan costs nothing.
Who it suits
Squoosh suits people who want to compress an image, review the result, adjust settings, and save it. It is also an option for those who want image processing to happen locally on their device.
