Visit MaskQR's free QR code generator, enter your URL or content, customize the design with colors and logos, then download as PNG or SVG. No signup required.

Question 2

What is the difference between static and dynamic QR codes?

Accepted Answer

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.

Question 3

How to create a QR code that never expires?

Accepted Answer

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.

Question 4

Can I add my logo to a custom QR code with logo?

Accepted Answer

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.

Question 5

Are QR codes safe for payments and sensitive data?

Accepted Answer

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 never reaches any server, providing maximum security.
