To create a high-definition (HD) product PNG of the RazorPay wallet, you can use the pngjs library. Here's a brief snippet to get you started:

const pngjs = require('pngjs');

// Load the image data from a file or URL
const img = pngjs.readFileSync('razorpay_wallet.png');

// Create a new PNG encoder
const encoder = pngjs.createEncoder({
  compressionType: pngjs.CompressionType.BRUTE,
});

// Encode the image to HD quality (e.g., 300 DPI)
encoder.setQuality(3);

// Encode the image data
const encodedImg = encoder.encode(img);

// Save the encoded image data to a new file
encodedImg.write('razorpay_wallet_hd.png');

This code uses the pngjs library to load an image, create a new PNG encoder, and encode the image data to HD quality (300 DPI). The resulting encoded image is then saved to a new file named razorpay_wallet_hd.png.

Note that you'll need to replace 'razorpay_wallet.png' with the actual path to your RazorPay wallet image.
