Questions

Short answers. The guides have the long ones.

Can I convert HTML, CSS, and JavaScript to APK?

Yes, when the page is self-contained. Put CSS in a style element and JavaScript in a script element. Separate folders, npm dependencies, and backend source code are not compiled by the builder.

Can I upload a ZIP file or a whole website folder?

No. Import one HTML file up to 100 KB or paste up to 100,000 characters per section. For a site with separate assets or a backend, host it over HTTPS and use Website mode.

Does an HTML APK work offline?

Bundled text and self-contained HTML can work offline. External images, fonts, scripts, and API calls still require a connection. Test the installed APK with airplane mode enabled.

Is this really free?

Yes. Create projects, customize the app, generate APK or AAB files, and download them at no charge. There are no credits, subscriptions, or paid unlocks. App-store registration and third-party services are separate.

Do I need an account?

No. Projects and builds are saved in this browser. Export a backup if you want to move to another device or browser.

Are my files or signing keys uploaded?

No. Project settings, HTML, icons, signing, and generated packages stay in your browser. This site serves pages and the Android template. Your hosted website still receives requests when the installed app opens it.

Can I publish on Google Play?

You can generate an AAB for a separate Play submission. You handle the developer account, listing, testing, and policies. A generated file is not store approval.

What if I clear browser data?

Projects, build files, and encrypted signing keys stored in the browser are removed. Files already downloaded to your device remain. Keep external backups; forgotten passwords cannot be recovered.
