Tool guide

PWA manifest generator: how it works

Practical information to understand the result and use this tool correctly.

About PWA manifest generator

This writes a manifest.webmanifest object. It does not generate icons, a service worker, or Open Graph tags.

A relative start URL must begin with a single slash. Absolute URLs must be https.

Icons are included only when you paste a path. The tool does not invent an icon URL.

How to use it

1Enter the app name, or use the UtiliHub example.
2Set the start URL, display mode, and optional theme colors.
3Copy the JSON. An empty name, a bad hex color, or a sizes value without an icon does not produce a file.
