QR Code Generator

QR codes bridge the physical and digital worlds, providing instant access to online destinations without cumbersome typing. The QR Code Generator equips you with enterprise-grade capabilities to craft codes that harmonise functionality with brand expression. Whether linking customers to a product page or encoding Wi-Fi credentials, each output is precision-rendered for clarity across print and screen.

Configurable payload templates span plain URLs, contact cards, payment links, multimedia assets and geolocation, ensuring seamless integration with marketing, logistics and support workflows. Fine-grained controls let you adjust error-correction resilience, margin spacing and pixel density while real-time previews eliminate guesswork. High-contrast palettes and dynamic frames foster inclusive engagement for users relying on diverse scanning environments.

Colour gradients, embedded logos, and stylised frames transform otherwise standard matrices into visually appealing assets that resonate with brand guidelines. Export options covering scalable vector graphics, high-resolution raster images and print-ready PDFs accommodate different production pipelines. Combined with URL parameter support, the generator can be pre-configured from campaign links for rapid deployment across global teams.

The following technical specifications summarise functional breadth, rendering capabilities, and implementation constraints.

18 payload types including URL, vCard, Wi-Fi, calendar and cryptocurrency.
Four ECC levels (L-H) compliant with ISO 18004:2015.
Customisable dot, eye and frame styles with live preview.
Linear or radial gradients supporting 0-360° rotation.
Logo overlay with scale control (10-50 % of symbol area).
Raster (PNG 2×) and vector (SVG, PDF 80 mm²) export.
Query-string parameters for programmatic pre-configuration.

Error Level	Recovery Capacity	Typical Use-Case
L	≈ 7 %	Screen displays, high clarity
M	≈ 15 %	Flyers, in-store signage
Q	≈ 25 %	Packaging, mild wear
H	≈ 30 %	Outdoor posters, heavy branding

Follow these steps to generate and deploy a fully branded QR code.

Select a Content icon that matches your payload.
Complete the context-sensitive fields displayed below the icon grid.
Open the Design fieldset and choose dot, eye and colour options Tip.
If branding is required, toggle Gradient or drop a logo into the upload zone.
Adjust Extras → Frame to add rounded, dashed or “Scan Me” borders Caution.
Review the live preview, then click an export button (PNG, SVG, PDF) for distribution.

Common questions are addressed below for rapid reference.

Which error-correction level should I choose?

Select L for crystal-clear screens, M or Q for printed collateral, and H when aggressive branding or surface damage is expected.

Can I embed multiple links in a single code?

No. Each symbol represents one payload, but you can link to a landing page that offers multiple destinations.

Are dynamic QR codes supported?

The generator produces static codes. Dynamic behaviour is achieved by redirecting the encoded URL through your own tracking service.

What logo file types are accepted?

PNG, JPEG and SVG up to 2 MB are accepted; transparent PNG is recommended for seamless integration.

How large should the printed code be?

Aim for ≥ 2 cm per side for every 0.3 m of expected scanning distance to maintain readability.

If a generated code fails to scan, consult the checklist below.

Blurry preview image — refresh the page and regenerate the code before exporting.
Scanner rejects gradient codes — increase contrast or disable gradient entirely.
Logo obscures data cells — reduce logo scale to ≤ 25 % or switch to higher ECC.
Frame text truncated — shorten the label or enlarge the overall size parameter.
Exported PDF prints blank — ensure your printer driver supports embedded raster images.

Critical: never invert colours without maintaining a solid dark-on-light contrast ratio; inverted palettes dramatically reduce scanner success rates.

Seasoned designers and developers can leverage these advanced techniques.

Batch-generate codes by appending URL parameters to a bookmarklet that pre-populates the interface.
Use SVG exports within design software to apply subtle drop-shadows without rasterisation.
Add UTM tags to marketing URLs before encoding to preserve analytics fidelity.
Create short vanity domains to keep symbol density low and scanning speed high.
Reserve quiet zones when embedding codes in illustrations to prevent false-positive detection.

Key terminology referenced throughout this document appears below.

ECC: Error-Correction Capability; redundancy that restores damaged data.
Quiet Zone: Blank margin surrounding the symbol, required for reliable detection.
Payload: Encoded string that scanners decode into actionable data.
vCard: Electronic business-card format defined by RFC 6350.
Raster Image: Bitmap graphic composed of pixels (e.g., PNG).
