PWA Manifest Generator
Fill in your app details, upload an icon, and get a ready-to-use manifest.json that makes your website installable.
App details
Used on the home screen when space is short.
Pages inside this scope open in the app window.
Colors the toolbar and task switcher on mobile.
Splash screen background while the app loads.
App icon
Upload a square image (PNG or JPG). It is resized in your browser to 192x192 and 512x512 PNG — the two sizes browsers require for install prompts.
192x192
512x512
No icon uploaded yet. The manifest is still valid, but browsers will not show an install prompt without the 192x192 and 512x512 icons.
manifest.json
Setup instructions
- Save the generated JSON as manifest.json and put the two downloaded icons next to it in your site root.
- Add this line inside the <head> of your pages:
<link rel="manifest" href="/manifest.json"> - Match your theme color on mobile browsers with:
<meta name="theme-color" content="#0d6efd"> - For a fully installable PWA you also need a service worker (a small JavaScript file that caches your pages for offline use) and HTTPS on your domain.
- Test it in Chrome DevTools: open the Application tab, then Manifest — Chrome lists any missing install requirements there.
