In addition to @sachin's answer, try avoid storing qr code IMAGES to database, instead store only its values. It will help you to have a compact size of your database which is easy to backup/restore the db.

You can use LEADTOOLS Barcode SDK technology in your application. https://www.leadtools.com/sdk/barcode For your use-case you can leverage the BarcodeWriter class to generate a QR barcode, add it to an image, and export that image to your database. Here is some sample code: // Write/Generate Barcode using LEADTOOLS SDK using (RasterImage _image = RasterImage.Create(2550, 3300, 24, 300, RasterColor.White)) { BarcodeEngine _engine = new BarcodeEngine(); BarcodeWriter _writer = _engine.Writer; // Set barcode options QRBarcodeData _qrData = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData; _qrData.SymbolModel = QRBarcodeSymbolModel.Model1AutoSize; _qrData.Value = "QR Data 1"; _qrData.Bounds = new LeadRect(0, 0, _image.ImageWidth, _image.ImageHeight); QRBarcodeWriteOptions _options = new QRBarcodeWriteOptions(); _options.GroupNumber = 0; _options.GroupTotal = 0; _options.HorizontalAlignment = BarcodeAlignment.Near; _options.VerticalAlignment = BarcodeAlignment.Near; _options.XModule = 30; _options.ECCLevel = QRBarcodeECCLevel.LevelL; // Write image to barcode _writer.WriteBarcode(_image, _qrData, _options); // Save image using (RasterCodecs codecs = new RasterCodecs()) codecs.Save(_image, @"FILE PATH TO OUTPUT IMAGE", RasterImageFormat.Png, 0); }

You can search and install Free Spire.Barcode via NuGet(https://www.nuget.org/packages/FreeSpire.Barcode/), then use the below code to generate QR code easily: using Spire.Barcode; using System.Drawing; namespace QRCode { class Program { static void Main(string[] args) { BarcodeSettings settings = new BarcodeSettings(); settings.Type = BarCodeType.QRCode; settings.Data = "Hello 123456789"; settings.Data2D = "Hello 123456789"; settings.QRCodeDataMode = QRCodeDataMode.AlphaNumber; settings.X = 1.0f; settings.QRCodeECL = QRCodeECL.H; BarCodeGenerator generator = new BarCodeGenerator(settings); Image image = generator.GenerateImage(); image.Save("QRCode.png"); } } } For more information, you can visit this documentation: https://www.e-iceblue.com/Tutorials/Spire.Barcode/Spire.Barcode-Program-Guide/Create-a-QR-Code-in-C.html
