You can absolutely use your existing website as a server to handle dynamic QR codes. The key is to set up a URL redirection mechanism on your website. This way, the QR code points to a specific URL on your website, and you can control where that URL redirects users.
Steps to Use a Website for Dynamic QR Codes
Here’s how you can set it up on your own website:
Identify a URL for Redirection
You’ll need to choose a URL on your website that will serve as the entry point for the dynamic QR code. For example:
https://yourwebsite.com/qr-redirect
This URL will remain the same in the QR code, but the destination it points to can change dynamically.
Implement a Redirection Script
Depending on the technology your website uses, you can create a script that handles the redirection. Here are a few examples of how to do this:
Using PHP (Common for Shared Hosting Websites)
If your website runs on PHP, you can use a simple redirect script:
<?php
// File: qr-redirect.php
// Set the target URL (this can be updated)
$redirect_url = "https://initial-destination.com";
// Perform the redirect
header("Location: " . $redirect_url);
exit();
?>
Place this qr-redirect.php file on your server, and your QR code will point to https://yourwebsite.com/qr-redirect.php.
- To change the destination, you just need to update the value of (
$redirect_url) in the PHP file. You can automate this through a simple content management system (CMS) or even manually via FTP or your hosting control panel.
Using .htaccess (For Apache Servers)
If your website runs on an Apache server and you have access to .htaccess, you can create a dynamic redirect rule:
# File: .htaccess
RewriteEngine On
RewriteRule ^qr-redirect$ https://initial-destination.com [L,R=301]
- In this example, the URL
https://yourwebsite.com/qr-redirectwill redirect tohttps://initial-destination.com. - To update the redirection, change
https://initial-destination.comto your new destination URL directly in the.htaccessfile.
Using JavaScript (For CMS Platforms like WordPress)
If you don’t have access to the server configuration and use a CMS like WordPress, you can set up a redirect page using JavaScript. Create a simple page like this:
<!-- File: qr-redirect.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="refresh" content="0;url=https://initial-destination.com">
<title>Redirecting...</title>
</head>
<body>
<p>If you are not redirected automatically, follow this <a href="https://initial-destination.com">link</a>.</p>
</body>
</html>
- You can create a page on your site like:
https://yourwebsite.com/qr-redirectand update the redirect URL in the HTML file when needed.
Generate the QR Code
Once you have your redirect URL set up (e.g., https://yourwebsite.com/qr-redirect), you can generate a QR code pointing to this URL using any QR code generator. Here’s how you can do it programmatically with Python:
import qrcode
# The URL of your website's redirect page
url = "https://yourwebsite.com/qr-redirect"
# Generate the QR code
qr = qrcode.QRCode(
version=1,
error_correction=qrcode.constants.ERROR_CORRECT_L,
box_size=10,
border=4,
)
qr.add_data(url)
qr.make(fit=True)
# Create the image of the QR code
img = qr.make_image(fill='black', back_color='white')
# Save the image
img.save("dynamic_qr_code.png")
You can use the generated QR code image wherever you want.

Updating the Target URL
Whenever you want to change the target URL (where the QR code points), you only need to update the redirect URL in your script (PHP, .htaccess, or HTML file). The QR code itself doesn’t need to be regenerated, as it will always point to your website’s redirect URL.
Benefits of Using Your Website
- Complete Control: You manage everything on your server, including the URL changes, without relying on third-party services.
- No Recurring Costs: Many dynamic QR code services charge monthly fees, but if you handle it yourself on your server, you avoid these costs.
- Customization: You can add custom logic, analytics, or tracking to your redirection, depending on your needs.
Optional: Use a CMS Plugin (For WordPress)
If your website is built on a CMS like WordPress, you don’t need to handle the redirection in code manually. There are plugins like Redirection for WordPress that allow you to create and manage redirects easily via a graphical interface. You can:
- Set up a redirect URL like
https://yourwebsite.com/qr-redirect. - Change the target URL anytime through the plugin interface.

Conclusion: Using a Website for Dynamic QR Codes
Yes, you can use any website you own to handle dynamic QR codes by setting up a URL redirect. You just need to generate a QR code pointing to a fixed URL on your website and change the destination URL as needed. You can manage this through a simple script or use CMS plugins if your website is built on a platform like WordPress.
