Favicon Generator

Generate a complete favicon package (16×16 to 512×512 PNGs, apple-touch-icon, and a web manifest) from a single image, fully client-side.

Source Image

For best results, use a square source image (ideally 512×512 or larger). Non-square images will be stretched to fill each size.

Frequently Asked Questions

Is my data sent to a server when using the Favicon Generator?
No. The Favicon Generator is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
What source image should I upload for best results?
Use a square source image, ideally 512×512 pixels or larger. Non-square images are stretched to fill each generated size, so a square source avoids any visible distortion.
Does the download include a legacy .ico file?
No. Building a proper multi-resolution .ico binary container is complex to do reliably in the browser, so this tool skips it. The zip instead ships PNG favicons at every standard size plus a site.webmanifest — this is sufficient for all modern browsers, which support PNG favicons via `<link rel=\"icon\" type=\"image/png\">`.
How do I wire the generated files into my site?
After downloading and extracting the zip into your site's root (or public) folder, copy the provided HTML snippet into your page's `<head>` — it links the 32×32, 16×16, and apple-touch-icon PNGs plus the web manifest.
Does the Favicon Generator store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the Favicon Generator compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the Favicon Generator work offline?
Yes. Once loaded, all code and assets required to run the Favicon Generator reside in your browser cache, enabling offline use without an active network connection.
