svg-to-ico .ico file generator

This utility can be used to convert a provided SVG file first into a collection of .PNG files and then it will combine these into an .ico format (such as is used by favicon.ico).

CLI Interface

The easiest way to run the utility is to install it globally:

npm install -g svg-to-ico

Once installed, the utility can be run as follows:

svg-to-ico input-file-name [ output-file-name ]

If the output file name is not specified, it will default to "favicon.ico" in the current working directory.

API

To use the API, you can install the package either globally or locally. The package exposes a single async function that accepts the following named parameters:

• input_name (string): Specifies the name of the input SVG file
• output_name (string): Optionally specifies the name of the output .ico file. If not specified, this will default to "favicon.ico" in the current working directory.
• sizes (number[]): Optionally specifies a list of sizes for individual PNG files in the ICO format. Each size will apply to both the width and the height but the aspect ratio of the original SVG will be preserved.

Example

const svg_to_ico = require("svg-to-ico");

svg_to_ico({
   input_name: "koala.svg",
   output_name: "koala.ico",
   sizes: [ 16, 24, 32, 64 ]
}).then(() => {
   console.log("file converted");
}).catch((error) => {
   console.error(`file conversion failed: ${error});
})
