# Manifest.json Benefits

Apple, Google, and Microsoft keep leaning on the Web App Manifest. Fill it out once and your icons, theme color, and analytics fall into place everywhere.

## What the manifest buys you

| Benefit | What you get |
| --- | --- |
| Install prompts that feel native | Chrome, Edge, and Android surface “Install app” banners only if your manifest declares icons, name, start_url, and display mode. |
| Offline-ready splash screens | The manifest gives you control over splash images, background colors, and maskable icons so offline launch looks intentional. |
| Consistent metadata everywhere | When search engines or social platforms inspect your manifest they pick up the same title, theme color, and icons you curated. |

## Anatomy of a modern manifest

These are the fields Lighthouse and Android actually inspect before displaying your icon.

| Field | Why it exists | Pro tip |
| --- | --- | --- |
| name & short_name | Controls install banner and launcher label text. | Keep short_name under 12 characters so it doesn't truncate on Android homescreens. |
| icons[] | Defines which PNGs power install surfaces, splash screens, and maskable logos. | Include 192, 256, 384, and 512 sizes with purpose: "any maskable" for best coverage. |
| start_url | Determines which route opens when a user launches from their dock. | Append ?source=pwa and read it server side to tailor analytics. |
| display | Switch between standalone, fullscreen, or minimal-ui experiences. | Use standalone plus theme_color to match your brand chrome. |

## Where manifest icons start

- 16x16
- 32x32
- 96x96
- 192x192

Rendered at true pixel dimensions. Tab favicons stop being useful around 32px; the manifest picks up from 192 and runs to 512, which is why an upscaled tab icon looks soft on an Android home screen.

## Starter JSON

```json
{
  "name": "Favicon Tools",
  "short_name": "Favicons",
  "start_url": "/?source=pwa",
  "display": "standalone",
  "scope": "/",
  "background_color": "#0f172a",
  "theme_color": "#312e81",
  "icons": [
    { "src": "/android-icon-192x192.png", "sizes": "192x192", "type": "image/png", "purpose": "any" },
    { "src": "/android-icon-512x512.png", "sizes": "512x512", "type": "image/png", "purpose": "any maskable" }
  ]
}
```

Drop this file into /public/manifest.json and the generator inside Favicon Tools will keep the icon array up to date whenever you export a new set.

## Release checklist

Keep this taped to your deployment dashboard so the manifest stays accurate after rebrands.

1. **Serve and link the manifest** — Serve the manifest at /manifest.json and expose it through <link rel="manifest" href="/manifest.json">.
2. **Check every icon resolves** — Ensure every icon referenced actually exists on your CDN and matches the declared size.
3. **Align the browser chrome** — Add theme-color and background_color meta tags to align browser chrome with your icon palette.
4. **Lint and audit before release** — Run npx next lint plus Lighthouse's PWA audit before every release to catch missing manifest fields.
5. **Scope the installed app** — Point the manifest scope at your primary app URL so installable shortcuts stay inside your domain.

## Automate updates

Store your manifest template next to your icon configuration. When CI builds a new favicon set, update the JSON and redeploy together.

> **Browsers cache the manifest hard:** Append ?v={buildId} to the <link rel="manifest"> tag so users download the latest copy instead of the one they installed with.

## Test like a native app

Install your site on iOS, Android, and desktop Chrome. Verify the splash screen, icon mask, and theme color match the manifest values.

QA teams like a simple checklist: install, launch offline, inspect icon quality, verify the analytics parameter.
