Since QR barcode is fairly robust, you can use a simple code to combine the images directly: using (Graphics g = Graphics.FromImage(bmp)) g.DrawImage(smaller_image, (bmp.Width - smaller_image.Width), (bmp.Height - smaller_image.Height)); If you want one library to handle both barcode creation and bitmap insertion, you could use the LEADTOOLS Barcode Pro library: https://www.leadtools.com/sdk/barcode-pro (Disclaimer: I’m an employee of LEADTOOLS vendor).

0	You can use Spire.Barcode library to generate QR Code with logo image. https://www.e-iceblue.com/Introduce/barcode-for-net.html The following is a basic example: using Spire.Barcode; using System.Drawing; namespace GenerateQRCodeWithLogo { class Program { static void Main(string[] args) { //Load a license file if you have one //Spire.License.LicenseProvider.SetLicenseFileFullPath("licensePath"); //Instantiate a BarcodeSettings object BarcodeSettings settings = new BarcodeSettings(); //Specify barcode type, data, etc. settings.Type = BarCodeType.QRCode; settings.QRCodeECL = QRCodeECL.M; settings.ShowText = false; settings.X = 2.5f; string data = "https://twitter.com"; settings.Data = data; settings.Data2D = data; //Add an image to QR code settings.QRCodeLogoImage = Image.FromFile(@"C:\Users\Administrator\Desktop\Logo.png"); //Instantiate a BarCodeGenerator object BarCodeGenerator generator = new BarCodeGenerator(settings); //Generate QR image Image image = generator.GenerateImage(); //Save the image image.Save("QR.png", System.Drawing.Imaging.ImageFormat.Png); } } } Ahmedsa, if this helps please login to Mark As Answer. \| Alert Moderator

        static void Main(string[] args)

        {

            //Load a license file if you have one

            //Spire.License.LicenseProvider.SetLicenseFileFullPath("licensePath");

 

            //Instantiate a BarcodeSettings object

            BarcodeSettings settings = new BarcodeSettings();

 

            //Specify barcode type, data, etc.

            settings.Type = BarCodeType.QRCode;

            settings.QRCodeECL = QRCodeECL.M;

            settings.ShowText = false;

            settings.X = 2.5f;

            string data = "https://twitter.com";

            settings.Data = data;

            settings.Data2D = data;

 

            //Add an image to QR code

            settings.QRCodeLogoImage = Image.FromFile(@"C:\Users\Administrator\Desktop\Logo.png");

 

            //Instantiate a BarCodeGenerator object

            BarCodeGenerator generator = new BarCodeGenerator(settings);

            //Generate QR image

            Image image = generator.GenerateImage();

            //Save the image

            image.Save("QR.png", System.Drawing.Imaging.ImageFormat.Png);            

        }

    }
