Private browser processing
Selected files are processed in the current browser session. Aftermath has no account, cloud file storage, or server-side file-processing job.
How to create your result
Generate a local favicon and PWA icon pack from one image when you need a ZIP containing favicon, Apple touch-icon, PNG sizes, and a starter manifest. The browser creates a separate package while keeping the source image in this session. Review generated paths, appearance, and platform-specific manifest requirements before deploying the assets.

Worked example
A square logo needs a local favicon and PWA starter pack with several PNG sizes and a reviewable manifest stub.
Starting facts
- The source remains available at sufficient resolution.
- Small icons may need optical simplification beyond automatic resizing.
Observed operation: Render the supported icon sizes locally, package named PNG files and include the generated starter manifest in a ZIP.
Review the result: Inspect the smallest icons, transparency, padding, filenames and manifest values before integrating the pack.
Boundary: The pack does not install icons, choose platform branding, create an ICO file or guarantee legibility at every size.
