Convert PNG to ICO in memory
$ npm install --save to-ico
const fs = require('fs');
const toIco = require('to-ico');
const files = [
fs.readFileSync('unicorn-16x16.png'),
fs.readFileSync('unicorn-32x32.png')
];
toIco(files).then(buf => {
fs.writeFileSync('favicon.ico', buf);
});Type: Array string
Array of PNG image buffers.
The images must have a size of 16x16, 24x24, 32x32, 48x48, 64x64, 128x128 or 256x256 and they must have an 8 bit per sample (channel) bit-depth (on Unix you can check this with the file command: RGB(A) is supported, while colormap is not, because it's 8 bits per pixel instead of 8 bits per channel, which is 24 or 32 bits per pixel depending on the presence of the alpha channel). These are limitations in the underlying pngjs library. If you have a colormap PNG you can convert it to an RGB/RGBA PNG with commonly used image editing tools.
