Icon Converter & Favicon Generator
Generate favicon, Apple touch icon, and PWA icon PNG sets from one source image in the browser.

PNG, JPG, or SVG recommended · up to 10MB · processed locally in your browser.
This tool runs in your browser. Inputs stay local and are not sent to any server.
How to use this result
A modern site usually needs more than one icon. Browsers, iOS home-screen shortcuts, Android/PWA installs, and search previews all use different preferred sizes.
This tool rasterizes one source image into practical favicon and app-icon PNG sizes, then creates a manifest.json starter and HTML link tags. The first version focuses on PNG output because it is broadly supported and predictable.
Files are processed locally in the browser. Avoid uploading private unreleased brand assets to tools that send files to a server; this page is designed to avoid that workflow.

Common questions
Q.Does it create a real .ico file?
The MVP creates PNG favicon sizes and HTML tags. Most modern browsers accept PNG favicons. ICO export can be added later if legacy compatibility becomes important.
Q.What source image works best?
Use a square 512×512 or larger PNG/SVG with enough padding. Very thin text or tiny details can disappear at 16×16.
Q.Are files uploaded?
No. Generation happens in the browser using Canvas and ZIP packaging.
