Nothing is uploaded
Your file is read into memory by the browser and processed there. No copy exists on any server, so confidential material stays confidential.
App builder tools
App builder tools produce the files that make a website behave like an app: a web app manifest, icons at every size a launcher asks for, a service worker with an offline page, and a complete Android Studio WebView project in Kotlin. Everything is generated inside your browser tab and handed back as a ZIP, so your artwork is never uploaded. Toolspea generates source and assets, not compiled binaries, and never publishes anything to a store on your behalf.
Android WebView App Builder
Turn a website into a full-screen Android Studio WebView project — icon, splash, permissions and all.
PWA App Builder
Generate the manifest, icons, service worker and offline page a website needs to become installable.
App Icon Generator
One square image in, every PWA and Android launcher icon out — including maskable and favicon.ico.
Web App Manifest Generator
Build a valid manifest.webmanifest field by field, with live JSON and a copy button.
