Turn App Details Into a Real manifest.json
This pwa manifest generator builds a real, spec-correct manifest.json from the fields you fill in, no starting from a template you have to edit by hand. As a web app manifest generator, it covers the properties that actually affect installability and the home screen experience: app name, a short name for constrained spaces, description, start URL, display mode, background and theme colors, orientation, and a standard three-size icon set. It's a genuine progressive web app manifest generator, not just a JSON template, the output is a complete, valid manifest ready to serve from your site.
How to Use This Manifest.json Generator
Fill in your app's name, and this manifest.json generator fills in every other field with sensible PWA defaults (standalone display, any orientation, white background, black theme color) that you can override. Leave Short name blank and it's derived automatically from App name. Click Generate to generate web app manifest output instantly, then copy the JSON or download it directly as manifest.json, plus the two HTML tags to add to your page's <head>.
What Each Manifest Field Controls
Here's what each field in the generated manifest actually does once your PWA is installed on a phone or desktop:
| Field | What It Controls |
|---|---|
| name | Full app name shown on the install prompt and app info screens |
| short_name | Shortened name shown under the home screen icon where space is limited |
| description | Shown in app store style install prompts and browser install UI |
| start_url | The page that opens when the installed app is launched |
| display | How much browser UI shows, standalone hides it, browser shows the normal tab |
| background_color | Splash screen background shown while the app is loading |
| theme_color | Color of the browser/OS chrome (status bar, task switcher) around the app |
| orientation | Locks the app to portrait, landscape, or leaves it unlocked (any) |
| icons | The home screen, app switcher, and splash screen images (64x64, 192x192, 512x512) |
Icons: What This Tool Generates vs What You Still Need to Provide
As a pwa icons manifest generator, this tool references three standard icon sizes (64x64, 192x192, 512x512) at fixed paths (/icons/icon-64x64.png, and so on) in the manifest it outputs, it doesn't create the actual PNG image files, that part still needs real image assets saved at those exact paths on your server. Use favicon-generator or image-resizer to produce properly sized PNGs from your logo, save them at the paths this manifest references, and the icon references here will resolve correctly.
