About

About this tool: Favicon Generator

Upload a PNG, JPG or WebP image and generate 16, 32, 48, 180, 192 and 512 pixel icons locally, with individual downloads, a ZIP package and suggested HTML markup.

The workflow is designed for common browser-supported image files, with a preview so you can inspect the result before downloading it.

Favicon Generator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.

How it works

Canvas creates a fresh PNG at each configured size. The ICO file uses the ICO header and directory structure with a PNG image payload, which modern browsers support.

Practical example

Upload a 1024 × 1024 logo, generate the package, then use favicon.ico for legacy browser requests and 180/192/512 PNGs for Apple touch and web-app contexts.

Important notes

Check the preview, output dimensions, format and file size before replacing an original image.

Privacy & processing

In the current NexterHub build, the primary image processing for this tool runs in the browser; keep sensitive originals backed up before editing.
