Which app icon sizes do I need?

PWA installability requires 192×192 and 512×512 PNG icons in the manifest. This generator produces both (plus maskable variants) from your single source image, locally.

Are the icons and manifest uploaded anywhere?

No. Rasterization runs on a canvas in your browser and the manifest is plain JSON generated client-side. Nothing is transmitted.
