Question 1

What is a PWA manifest.json file?

Accepted Answer

The manifest.json file is a JSON file that tells the browser how your Progressive Web App should behave when installed on a device — including the app name, icons, theme color, display mode and start URL.

Question 2

What display modes are supported?

Accepted Answer

Supported display modes include: fullscreen (no browser UI), standalone (looks like a native app), minimal-ui (minimal browser controls), and browser (standard browser tab).

Question 3

Do I need to upload any files?

Accepted Answer

No. This tool runs entirely in your browser. Just fill in the form and copy the generated manifest.json code — nothing is sent to any server.
