Software generador de códigos QR dinámicos (Herramientas gratuitas y de pago)

Static QR Codes

Static QR codes contain fixed, unchangeable information encoded directly within their pattern. These codes work well for permanent information such as website URLs, contact details, or Wi-Fi credentials. Organizations often use unlimited static QR codes for basic applications where information remains constant. While static QR codes are free to generate and require no ongoing maintenance, their permanent nature means any information update requires creating and distributing new codes.

Dynamic QR Codes

Dynamic QR codes store a short, redirectable URL that connects to a customizable destination. Users can modify the linked content without changing the QR code's appearance. Key advantages of dynamic QR codes include:

• Update destination URLs, text, or media without generating new codes
• Monitor QR code scans, user locations, and scanning times
• Create multiple QR codes for different marketing campaigns
• Connect with Google Analytics for detailed user behavior insights
• Enable or disable QR codes remotely

Key Features

IronQR's flexibility in handling QR code generation and reading makes it particularly useful for developers. The library can create QR codes in different image formats, adjust error correction levels, and customize the appearance of QR codes to match application requirements.

For applications that need to process many QR codes, IronQR includes batch processing capabilities that can efficiently handle bulk generation. The library also provides robust error handling and validation features. Plus, since all processing happens locally within the application, developers don't need to worry about API rate limits or internet connectivity for QR code operations.

Create Dynamic QR Codes

Here's a basic example of how developers can use IronQR for creating QR codes with dynamic URLs:

using IronQr;
using IronSoftware.Drawing; // Required for image manipulation

// The URL that the QR code will represent
string dynamicUrl = "https://shorturl.at/dfKpj";

// Create a QR code object with the dynamic URL
QrCode myQr = QrWriter.Write(dynamicUrl);

// Save the QR code as a Bitmap object for manipulation or display
AnyBitmap qrImage = myQr.Save();

// Generate a unique file name using a timestamp
string fileName = $"qr_{DateTime.Now:yyyyMMddHHmmss}.png";

// Save the QR code bitmap as a PNG file
qrImage.SaveAs(fileName);

using IronQr;
using IronSoftware.Drawing; // Required for image manipulation

// The URL that the QR code will represent
string dynamicUrl = "https://shorturl.at/dfKpj";

// Create a QR code object with the dynamic URL
QrCode myQr = QrWriter.Write(dynamicUrl);

// Save the QR code as a Bitmap object for manipulation or display
AnyBitmap qrImage = myQr.Save();

// Generate a unique file name using a timestamp
string fileName = $"qr_{DateTime.Now:yyyyMMddHHmmss}.png";

// Save the QR code bitmap as a PNG file
qrImage.SaveAs(fileName);

Imports IronQr
Imports IronSoftware.Drawing ' Required for image manipulation

' The URL that the QR code will represent
Private dynamicUrl As String = "https://shorturl.at/dfKpj"

' Create a QR code object with the dynamic URL
Private myQr As QrCode = QrWriter.Write(dynamicUrl)

' Save the QR code as a Bitmap object for manipulation or display
Private qrImage As AnyBitmap = myQr.Save()

' Generate a unique file name using a timestamp
Private fileName As String = $"qr_{DateTime.Now:yyyyMMddHHmmss}.png"

' Save the QR code bitmap as a PNG file
qrImage.SaveAs(fileName)

IronQR optimizes memory usage and processing speed for handling large numbers of QR codes. Whether generating a single QR code or processing thousands in batches, IronQR maintains consistent performance.
