PWA manifest and favicon audit PWA manifest and favicon audit

Audit PWA manifest and icons online

Enter a website URL to check its web app manifest, maskable icons, theme and background colors, service worker registration, apple-touch-icon and favicon availability.

The audit fetches the page server-side, resolves linked assets and reports practical installability issues before a PWA is shipped.

The tool runs directly in the browser and is ready for quick checks without installing software.
Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
Use fullscreen mode when you need more space for long text, structured data or large result blocks.
Copy buttons are available on generated output so results can be reused in code, documents or support chats.
Most operations are deterministic: the same input and options produce the same output.
For sensitive content, prefer local browser tools and review the result before sharing it further.
