QR Code Generator

Q: How does your QR code generator work?

Our QR code generator uses the QRCode.js library to create QR codes directly in your browser. When you enter your content (URL, text, contact info, etc.), select colors, and optionally add a logo, the tool generates a matrix barcode that encodes your information. The entire process happens locally in your browser - no data is sent to our servers.

Q: What types of QR codes can I create?

You can create 5 types of QR codes: 1) URL codes for websites, 2) Business Card codes with contact details, 3) Event codes with calendar information, 4) Text codes for plain text messages, and 5) WIFI codes to share network credentials.

Q: How do I scan a QR code?

Most modern smartphones can scan QR codes using their built-in camera app. Simply open your camera, point it at the QR code, and tap the notification that appears. If your camera doesn't recognize QR codes, you can download a free QR scanner app from your device's app store.

Q: Are the QR codes I generate secure?

Yes, all QR codes are generated locally in your browser. We don't store or track the content of your QR codes. For sensitive information, we recommend using our tool offline by saving the page to your device.

Q: What's the best size for a QR code?

The ideal size depends on usage: 1) For print materials (business cards, flyers), 1-2 inches (2.5-5 cm) is sufficient. 2) For digital screens, at least 200x200 pixels. 3) For large format printing (posters, banners), 4-8 inches (10-20 cm) ensures easy scanning from a distance.

Q: Can I customize the colors of my QR code?

Yes, you can choose any two colors for your QR code - one for the dark modules and one for the light background. We recommend high contrast combinations (like black on white) for best scan reliability. Avoid similar colors that might reduce readability.

Q: How much data can a QR code store?

QR code capacity depends on the version and error correction level: 1) Numeric only: up to 7,089 characters 2) Alphanumeric: up to 4,296 characters 3) Binary/bytes: up to 2,953 bytes 4) Kanji: up to 1,817 characters. Our generator automatically selects the optimal version for your content.

Q: Why add a logo to my QR code?

Adding a logo: 1) Brands your QR code for recognition 2) Increases trust (users know where the code leads) 3) Makes your code visually distinctive. Our generator automatically adjusts error correction to ensure your logo doesn't prevent scanning.

Q: What's the difference between static and dynamic QR codes?

Static QR codes (like ours) contain fixed information that can't be changed after creation. Dynamic QR codes use a short URL that redirects to your content, allowing you to change the destination later. Static codes are simpler and don't require a subscription, while dynamic codes offer analytics and editability.

Q: How long do QR codes last?

QR codes don't expire - they'll work as long as: 1) The physical code remains undamaged 2) The content remains accessible (for URLs) 3) The scanning technology remains compatible. Properly printed QR codes can last decades. For URLs, ensure the linked content remains available.

How does your QR code generator work?

Our QR code generation process:

You select the type of QR code you want to create
Enter the relevant content (URL, contact info, etc.)
Customize the design with colors and optional logo
The browser generates the QR code matrix locally
The visual QR code appears for download

Key technical details:

Uses QRCode.js library for client-side generation
No server processing - everything happens in your browser
High error correction (level H) for reliability
Automatic version selection based on content length

What types of QR codes can I create?

Our generator supports 5 specialized QR code types:

Type	Format	Best For
URL	Standard web link	Website promotion, social media
Business Card	vCard (MECARD format)	Contact sharing, networking
Event	vCalendar format	Event invitations, tickets
Text	Plain text	Messages, instructions
WIFI	Network credentials	Guest network access

Each type automatically formats your content for optimal scanning.

How do I scan a QR code?

Scanning QR codes is simple:

Smartphone Camera: Most modern phones can scan QR codes directly through the camera app
Dedicated Scanner Apps: Apps like QR Scanner (iOS) or Barcode Scanner (Android) offer additional features
Webcam Scanning: Some computers can scan using webcam software

Scanning tips:

Ensure good lighting
Hold steady about 6-12 inches from the code
Position the code within the camera frame
Clean smudges from printed codes

Are the QR codes I generate secure?

Our QR code generator prioritizes security:

Local Processing: All generation happens in your browser - no data is sent to our servers
No Storage: We don't store or log the content of your QR codes
Privacy Protection: No tracking of generated codes
Offline Capable: You can save the page and use it without internet

For sensitive information, we recommend:

Using the tool offline
Not sharing confidential data via QR codes
Testing codes before distribution

What's the best size for a QR code?

Optimal QR code sizes vary by use case:

Medium	Recommended Size	Scanning Distance
Business Cards	0.8" x 0.8" (2cm)	Up close
Flyers/Postcards	1.5" x 1.5" (4cm)	Arm's length
Posters	4" x 4" (10cm)	Several feet
Billboards	3' x 3' (1m)	50+ feet
Digital Screens	200x200 pixels	Varies

Remember: The scanning distance should be about 10x the width of the QR code.

Can I customize the colors of my QR code?

Yes! Our color customization options:

Two-Tone Design: Choose any dark color for the modules and any light color for the background
Brand Matching: Use your brand colors for consistency
Accessibility: Ensure sufficient contrast (minimum 70%)

Color best practices:

Dark colors work best for the modules (black, dark blue, etc.)
Light backgrounds improve scan reliability
Avoid red/green combinations (colorblind accessibility)
Test colored codes before mass printing

How much data can a QR code store?

QR code capacity depends on several factors:

Data Type	Max Characters	Example Use
Numeric only	7,089	Serial numbers, IDs
Alphanumeric	4,296	URLs, basic text
Binary	2,953 bytes	Small files, encrypted data
Kanji	1,817	Asian language text

Our generator automatically selects the smallest possible version (1-40) that fits your content while maintaining high error correction.

Why add a logo to my QR code?

Adding a logo provides several benefits:

Brand Recognition: Makes your code instantly identifiable
Increased Trust: Users know the source of the code
Visual Appeal: More attractive than standard codes
Professionalism: Shows attention to detail

Logo best practices:

Use a simple, high-contrast logo
Keep it centered and proportional
Don't cover more than 30% of the code area
Test scanability after adding the logo
Use our built-in logo positioning for optimal placement

What's the difference between static and dynamic QR codes?

Comparison of static and dynamic QR codes:

Feature	Static QR Codes	Dynamic QR Codes
Content	Fixed, can't be changed	Editable after creation
Tracking	No analytics	Scan statistics available
Cost	Free (like our tool)	Usually requires subscription
Use Case	Permanent links, contact info	Marketing campaigns, changing info
Appearance	Standard QR design	Often uses short URLs

Our generator creates static QR codes - perfect for most personal and business needs that don't require changing content.

How long do QR codes last?

QR codes have different longevity depending on use:

Physical Codes: Will work indefinitely if undamaged (consider material durability)
Digital Codes: Remain functional as long as the display works
URL Codes: Depend on the linked content remaining available

Factors affecting longevity:

Print quality and material (avoid thermal paper)
Environmental conditions (sunlight, moisture)
Physical wear (scratches, fading)
Content availability (for web links)
Technology changes (unlikely with standard QR)

For printed materials, we recommend high-quality printing on durable materials with protective coatings.
