# HTML to App — HTML 2 APK Builder

> HTML to App (https://www.htmltoapp.net) converts an HTML file, a ZIP of a web project or an HTML5 game into a signed Android APK, or an AAB for Google Play. Builds run in the cloud from two free Android apps: HTML & ZIP to APK Builder (https://play.google.com/store/apps/details?id=htmltoapk.zipfiletoapk.htmltoapkbuilder) for HTML/ZIP/games and Website to App (https://play.google.com/store/apps/details?id=webintoapp.websitetoapp.apkgenerator.convertwebsitetoapp) for live website URLs.

Key facts:
- Free plan: signed APK, no watermark, no expiry; 5 MB of zipped content; short cooldown between builds.
- Pro ($5/month, Google Play subscription): AAB, own signing key, splash screen, onboarding slides, native bottom tabs, push notifications via OneSignal, branded page loaders, 18 MB content, no cooldown.
- Bundled files are served from https://appassets.androidplatform.net/web/ (not file://), so ES modules, fetch(), WebAssembly, localStorage and IndexedDB work offline.
- Apps run on Android 7.0+ in the Chromium-based Android System WebView. Not available in the WebView: Web Push, Web Share, Web Bluetooth/USB/NFC, downloads, PDF display, window.print(); navigator.vibrate is ignored.
- ZIP rules: index.html at the root (or one wrapping folder), relative paths (root-relative /paths break), case-sensitive names.
- Android only; no iOS builds. No native plugin system (no AdMob SDK, no Play Billing).
