About

Generates QR codes for 8 content types (URL, email, phone, SMS, WiFi, vCard, location, plain text) with 4 error correction levels (L/M/Q/H) for damage tolerance. Features logo overlay placement, custom color pickers for foreground/background, cell size and margin configuration, multiple output formats (SVG, PNG, JPEG), batch history with export, and copy-image functionality.

QR codes are ubiquitous for contactless sharing, marketing, and authentication. Provides a comprehensive generator supporting various data types with design customization that goes beyond basic black-and-white QR codes.

Who should use this tool?

Marketing professionals, event organizers, business owners, software developers integrating QR functionality, and anyone needing custom-styled QR codes for sharing information.

Common use cases

Generate QR codes for URLs to drive traffic to websites, landing pages, or app store links
Create WiFi credential QR codes for guest network access in offices, cafes, and hotels
Generate vCard QR codes for digital business cards at networking events and conferences
Create location QR codes with coordinates for mapping and navigation integration
Design branded QR codes with logo overlays and custom colors for marketing materials
Generate batch QR codes for event check-in, inventory tracking, or asset labeling systems

How to Use

Select the QR content type from 8 options: URL, Email, Phone, SMS, WiFi, vCard, Location, or Plain Text

Fill in the data fields specific to the selected type (e.g., for WiFi: SSID, password, encryption type)

Choose the error correction level: L (7%), M (15%), Q (25%), or H (30%) data recovery; higher levels allow larger logos

Customize appearance: set foreground/background colors using the color pickers, adjust cell size (1-10) and margin (0-4)

Optionally upload a logo image for center overlay; the tool automatically determines the max logo size based on ECC level

Select output format: SVG (scalable), PNG (with transparency), or JPEG (white background); download or copy to clipboard

Examples

Input: Type=WiFi, SSID="GuestNetwork", password="securepass", ECC=H -> Output: QR code that, when scanned, prompts to connect to GuestNetwork with the provided password

Input: Type=URL, content="https://example.com", colors=#FF0000 (foreground), #FFFFFF (background), logo=uploaded.png -> Output: Red QR code with center logo, scannable to example.com

Best Practices

Use error correction level H (30%) when adding a logo overlay to ensure the QR code remains scannable
Maintain high contrast between foreground and background colors to ensure reliable scanning (avoid light-on-light)
Test generated QR codes with multiple scanner apps before printing on materials or publishing
Use SVG format for print materials (posters, business cards) since it scales without quality loss
Keep the QR code size reasonable (at least 2cm x 2cm for print, 150x150px for digital) to ensure scanability

Common Mistakes

Using low error correction (L/M) with a logo overlay, making the QR code unscannable due to data loss
Choosing low-contrast color combinations like light gray on white that scanners cannot read
Making QR codes too small (under 1cm) on printed materials where scanning distance is more than a few inches
Not testing the generated QR code before mass production, discovering issues after printing
Over-customizing with multiple colors and gradients that interfere with the QR code's timing patterns

FAQ

Can I scan QR codes with this tool? No, this is a generator only; use a separate scanner app or tool for decoding.

What's the maximum data capacity? Depends on version and ECC level; URL QR codes typically handle up to ~3KB of data.

Does the logo overlay affect scanability? Yes, higher ECC levels compensate for logo-related data loss; use at least level Q (25%) with logos.

Are the generated QR codes standard compliant? Yes, they follow ISO/IEC 18004 standards for QR Code symbology.
