Frequently Asked Questions About QR Codes
Everything you need to know about creating, customizing, and using QR codes.
What is the difference between static and dynamic QR codes?
Static QR codes contain fixed data that cannot be changed after generation. They are permanent and free to create. Dynamic QR codes can be edited after creation and include scan tracking, but typically require a subscription. MaskQR provides free static QR codes with full customization options.
How to create a QR code that never expires?
Static QR codes never expire because the data is encoded directly in the pattern. MaskQR generates permanent QR codes that work forever — no server dependency, no expiration date. Your QR codes will always work as long as the content (URL, text, etc.) remains valid.
Can I add my logo to a custom QR code with logo?
Yes, MaskQR supports logo embedding in your QR codes. Simply upload your logo image through the generator interface. We recommend using H-level error correction when adding a logo to ensure reliable scanning. The logo is centered automatically and can be adjusted in size.
Are QR codes safe for payments and sensitive data?
QR codes themselves are just encoded data — they are as safe as the content they contain. MaskQR generates all QR codes locally in your browser, meaning your sensitive data (WiFi passwords, contact info, payment URLs) never reaches any server, providing maximum security.
How to create a digital business card QR code (vCard)?
Select the vCard content type in our QR code generator. Enter your name, organization, phone number, email, and website URL. The generator will create a scannable QR code that, when scanned, prompts the user to save your contact information directly to their phone.
What is the best format to download QR codes — PNG or SVG?
Use PNG for digital applications like websites, emails, and social media. Use SVG for print materials like business cards, posters, and packaging. SVG is a vector format that scales to any size without losing quality, making it ideal for professional printing.
