an I customize the design of my QR codes?
Yes! QRGen allows users to customize QR codes by:

Adding a logo or icon in the center
Adjusting shapes of modules (dots and patterns)
Generating dynamic QR codes with editable content
This makes QR codes more attractive and suitable for branding, marketing, and professional use.
What is the difference between static and dynamic QR codes?
Static QR Codes: Once created, the content cannot be changed. Ideal for permanent links, contact details, or simple uses.
Dynamic QR Codes: Allow you to update the destination, track analytics (scan count, location, device type), and make changes without reprinting. Dynamic QR codes are ideal for businesses, campaigns, and marketing materials that may need updates.
How secure are the QR codes I create?
QRGen prioritizes privacy and security. We do not store any personal information or scan data. However, the security of the content you encode depends on what information you put in the QR code. For sensitive data, always use dynamic QR codes with password protection or secure links.
Can I track the performance of my QR codes?
Yes, but only with dynamic QR codes. QRGen allows tracking of:
Number of scans
Location of scans
Device type
Time and date of scans
This helps businesses and marketers measure engagement and optimize campaigns effectively.
How do I create a QR code for WiFi access?
Select the WiFi QR code option, enter the network name (SSID), password, and encryption type (WPA/WPA2). When scanned, the QR code will automatically connect the user’s device to the WiFi network without typing the credentials. This is perfect for cafes, offices, or public spaces.
Can I use QR codes in education?
Absolutely! Teachers and educators can use QR codes to:
Share class notes, PDFs, or slides
Link to online videos or interactive content
Assign homework or quizzes
Track attendance by scanning QR codes at the start of class
This makes learning more interactive, organized, and paperless.
Are QR codes compatible with all devices?
Yes. QR codes generated by QRGen are fully compatible with most modern smartphones and tablets. Almost all devices with cameras can scan QR codes without additional apps, making them universally accessible.
How fast can I generate a QR code?
QRGen generates QR codes instantly—usually within a few seconds. You can immediately download, print, or share the code digitally without waiting.
Can I print my QR codes on products or marketing material?
Yes. QR codes can be downloaded in high-resolution formats such as PNG or SVG, making them suitable for business cards, flyers, posters, packaging, or merchandise.
Do QR codes expire?
Static QR codes do not expire. Dynamic QR codes remain functional as long as the target URL or destination is active and not deleted. For campaigns or temporary content, dynamic QR codes are preferred for better control.
Can I generate QR codes for payments?
Yes. QRGen supports QR codes for PayPal, UPI, and other digital payment platforms, allowing businesses and individuals to accept payments quickly and safely.
How do I create a vCard QR code?
Select the vCard option, fill in your contact details such as name, phone, email, and address. QRGen generates a QR code that, when scanned, instantly saves the contact information to the user’s device. This is perfect for networking and business events.
Can I share documents via QR codes?
Yes. Upload your documents to a hosting platform like Google Drive or Dropbox, then generate a QR code linking to the document. Users can scan the code to access the file instantly.
Is there a limit to how much data a QR code can store?
QR codes have data limits depending on the type:
Numeric: up to 7,089 characters
Alphanumeric: up to 4,296 characters
Binary (bytes): up to 2,953 bytes
Dynamic QR codes are recommended for more flexible content management and easier updates.
How do I edit a QR code after creating it?
Only dynamic QR codes can be edited after creation. You can change the destination URL, update text, or switch documents without reprinting the QR code. Static QR codes cannot be modified once generated.
Can QR codes be used in marketing campaigns?
Absolutely. QR codes are widely used for:
Linking print ads to websites
Promoting discounts or coupons
Interactive content for social media campaigns
Tracking user engagement through dynamic QR codes
This helps businesses increase visibility and measure marketing performance efficiently.
How private is the information I encode?
QRGen does not collect or store your data. Once a QR code is generated, the information is deleted from our system. You remain fully in control of your content.
Can I generate multiple QR codes at once?
Currently, QRGen allows generating one QR code at a time, but you can quickly repeat the process to create multiple codes. Dynamic QR codes are useful for managing multiple codes efficiently.
Can QR codes include multimedia content?
Yes. QR codes can link to videos, audio files, PDFs, images, and interactive web pages. This makes QR codes a versatile tool for education, marketing, and events.
How do I ensure my QR code works properly?
Always:
Test the QR code on multiple devices before sharing.
Use dynamic QR codes for frequently updated content.
Avoid excessive customization that reduces scan reliability.
Use high-resolution images if printing the code.
