About this tool

A web app manifest turns a website into an installable Progressive Web App — it tells the browser the app’s name, icons, theme colours and how it should display when launched from the home screen. This generator builds a valid manifest.webmanifest from your settings, with a live preview and the iOS Safari head tags that PWAs also need.

Getting the manifest right is what makes “add to home screen” produce a proper app-like experience rather than a browser shortcut with a blank icon. The generator ensures the required fields are present and correctly formatted, and includes the extra meta tags iOS needs since it does not fully honour the manifest.

It runs in your browser, so it is instant. Use it when making a site installable, setting up a PWA, or fixing an install experience that shows the wrong icon or colours.

Frequently asked questions

What is a web app manifest?
A JSON file (manifest.webmanifest) that describes a Progressive Web App — its name, icons, theme colours and display mode — so it can be installed and launched like an app.
Why does it also generate iOS head tags?
iOS Safari does not fully honour the manifest, so additional meta tags are needed for a correct home-screen icon and appearance. The tool includes them.
What does “display mode” control?
How the installed app appears — for example standalone (no browser chrome) versus a normal browser tab — which shapes the app-like experience.
Is it done locally?
Yes. The manifest is generated in your browser with a live preview and nothing uploaded.
