assets-generator 简介
assets-generator is a web-based tool that automatically generates the full set of assets required for Progressive Web Apps (PWAs), including favicons, Apple Touch Icons, Windows tile images, and web app manifests.
It accepts a single high-resolution source image and outputs optimized, correctly sized assets across multiple formats and densities. The tool runs entirely in the browser and requires no configuration or installation.
The generator is built with modern web technologies and leverages Sharp for image processing. It is hosted at vite-pwa-org.netlify.app/assets-generator/ and is open-source on GitHub.
