Web App Manifest Generator
The web app manifest controls how your site appears when installed on a phone or desktop — name, colours and icons. Fill in the basics and get valid JSON plus the link tag to add to your pages.
Use the tool
How to use the Web App Manifest Generator
- Enter your app name, colours and icon URLs.
- Adjust any optional settings to match your page, business or campaign.

Frequently asked questions
What icon sizes do I need?
At minimum 192×192 and 512×512 PNG icons. The 512 icon is used for splash screens and should have safe padding.
Does a manifest make my site a PWA?
It is one of the requirements — you also need HTTPS and, for installability in Chrome, a service worker.
Where does the file go?
Site root is typical, referenced by a link tag in every page's head.
