Are the QR codes generated on this website free and static?

Yes, all QR codes generated here are 100% free and static. They do not expire, have no scan limits, require no account registration, and contain no middle-man redirect links.

Do QR codes with custom logos scan reliably on all mobile cameras?

Yes. Our generator automatically applies Reed-Solomon Level H Error Correction (30% redundancy) and maintains a safe non-destructive center boundary so iOS, Android, and industrial scanners decode the code in milliseconds.

What is the best export format for professional billboard and t-shirt printing?

For commercial offset printing, signage, flyers, packaging, and t-shirts, download the Vector SVG format or high-resolution 4K PNG (2400x2400px at 300 DPI). Vector SVG can scale infinitely without pixelation or blurriness.

How does the WiFi QR code work without typing passwords?

The WiFi QR code encodes the SSID, encryption standard (WPA/WPA2/WPA3), and password into the standard WIFI:S:ssid;T:WPA;P:password;; format. When scanned with iOS Camera or Android Google Lens, the device displays a 1-tap "Join Network" prompt.

What is the minimum physical print size for a QR code on a business card?

The minimum recommended physical size for standard business cards is 2 x 2 cm (0.8 x 0.8 inches). For high-density QR codes (such as detailed vCards with full addresses), 2.5 x 2.5 cm (1 x 1 inch) is recommended.

Can I generate a digital business card (vCard) QR code with contact details?

Yes! Select the vCard tab to enter your full name, organization, job title, phone numbers, email, website, and physical address. Scanning the code prompts smartphones to save the contact directly to their address book.

Is my data private and secure when creating QR codes?

100% private. All QR matrix encoding and visual rendering occur strictly client-side inside your browser via WebAssembly and HTML5 Canvas. Your passwords, URLs, and personal contact details are never sent or stored on any external server.

What is the difference between Static and Dynamic QR codes?

Static QR codes encode the data directly into the pixel matrix, meaning they work forever offline with zero risk of link expiration or subscription costs. Dynamic QR codes redirect through a paid third-party server URL, which can break if the service shuts down.

Reed-Solomon Error Correction Levels (L, M, Q, H)

QR codes use advanced algebraic error correction so they remain completely scannable even when partially obscured, scratched, or branded with center logos.

Level L (Low)

~7% Data Recovery

Clean digital screens & high-density URLs where maximum data capacity is required.

Level M (Medium)

~15% Data Recovery

Standard industrial default. Great for menus, marketing flyers, and general web links.

Level Q (Quartile)

~25% Data Recovery

Factory environments, outdoor signage, or surfaces subject to dirt and weathering.

Level H (High - Best for Logos)

~30% Data Recovery

Essential when adding custom brand logos, complex gradients, or artistic frames.

QR Code Scannability Checklist for Graphic Designers

Maintain 4:1 High Contrast RatioEnsure dark foreground dots stand out sharply against light backgrounds. Avoid low-contrast pastel-on-pastel combinations.

Preserve the 4-Module Quiet ZoneNever crop the blank padding perimeter around the QR code. Camera sensor algorithms require this quiet zone to identify position markers.

Limit Logo Size to 25% AreaWhen placing center logos, never exceed 25–30% of the total matrix area and always use Level H error correction.

Avoid Heavy Curvature & GlareWhen printing on bottles, cans, or reflective shrink wrap, position the QR code along flat vertical axes to prevent optical distortion.

Test with Multiple Camera AppsAlways test printed samples with native iOS Camera, Android Google Lens, and low-light sensors before executing large print runs.

Use Vector SVG for Commercial PrintFor billboard banners, packaging, and magazines, export SVG vector format to ensure razor-sharp edges at 300+ DPI.
