How to Generate Custom QR Codes Online
Define QR Code Data
Input your content—URLs linking to websites or landing pages, plain text messages, vCard contact information (name/phone/email), WiFi network credentials (SSID/password/encryption), or SMS/email data. The tool selects optimal encoding mode (numeric, alphanumeric, or byte) based on data type.
Style and Brand QR Matrix
Customize foreground/background colors (maintaining luminance contrast ratio above 4.5:1 for scannability), upload logo overlay centered in the QR matrix, choose error correction level (L/M/Q/H—higher levels enable 30% damage recovery), and adjust output dimensions (128px-1024px).
Validate Scan Reliability
Preview the generated QR code featuring finder patterns (corner squares), alignment markers, and Reed-Solomon error correction redundancy. Test scannability using your smartphone camera app before finalizing—ensuring the encoded data decodes correctly across different scanner apps.
Export in Multiple Formats
Download as PNG (raster bitmap for web/digital), SVG (vector format scaling infinitely for print without pixelation), or PDF (professional printing on business cards, flyers, posters). Browser-generated entirely client-side—your data never uploads to external servers.

About QR Code Generation
Generate custom QR codes (Quick Response codes) for URLs, text, contact information (vCard), WiFi credentials, email addresses, and SMS messages. Our browser-based tool uses modern QR code encoding libraries to convert your data into scannable 2D barcodes with customizable colors, logos, and error correction levels. Perfect for marketing materials, business cards, product packaging, and contactless information sharing.
Unlike desktop software requiring installation, this tool generates QR codes instantly in your browser using client-side processing—no uploads, complete privacy. Supports multiple output formats (PNG for web/print, SVG for scaling, PDF for professional printing) with adjustable dimensions (128px-1024px) and error correction settings for durability and logo overlay compatibility.
How QR Codes Work
QR codes (Quick Response codes) are 2D barcodes that store information in a grid of black and white squares. Unlike standard barcodes that only hold numbers, QR codes can store websites, text, and contact info. When you scan the pattern with your phone camera, it instantly decodes the grid and takes you to the stored link or content.
Ensuring Your QR Code Scans Every Time
Contrast is King: The most common reason a QR code fails to scan is poor color contrast. Scanners need to clearly distinguish the dark pattern from the light background.
• Do: Use dark patterns on light backgrounds (e.g., Black on White, Dark Blue on White).
• Don't: Use light patterns on dark backgrounds (inverted) or colors that are too similar (e.g., Yellow on White).
Adding Logos Safely
You can make your QR code stand out by adding your brand's logo in the center. QR codes have a built-in "error correction" feature that allows them to still work even if part of the code is covered.
Tip: Keep your logo size reasonable (usually under 30% of the area) and make sure it doesn't cover the three large square markers in the corners, which are used for alignment.
Understanding Error Correction
Think of this as a backup system for your data.
• Low (L): Best for simple codes with no logo. Produces the cleanest looking patterns.
• Medium (M): Good standard balance.
• Quartile (Q): Recommended when adding a logo.
• High (H): Maximum protection. Use this if the QR code might get dirty or damaged (like on outdoor posters or product packaging), but it makes the pattern look denser/busier.
Use Cases & Best Practices
- Business Cards: vCard QR codes for instant contact import (name, phone, email, website)
- Marketing: Link to landing pages, promotional videos, product info (use URL shorteners for analytics)
- WiFi Sharing: WiFi QR codes auto-connect guests (SSID, password, encryption type)
- Payments: Link to payment gateways or UPI IDs for contactless transactions
- Event Tickets: Unique QR codes for entry verification and attendance tracking
Frequently Asked Questions
How do I create a QR code online for free?
To create a QR code online free: (1) Enter your content (URL, text, contact info, WiFi details, etc.), (2) Choose your QR code type from the options, (3) Customize the design (add logo, choose colors, adjust size), (4) Preview your QR code, (5) Download in PNG, SVG, or PDF format. Our tool generates QR codes instantly with no registration required.
What types of QR codes can I create?
Our QR code generator supports multiple types: URL/Website links, plain text, contact information (vCard format), WiFi network credentials, email addresses, SMS messages, and more. Each type has specific fields to fill in, making it easy to create the right QR code for your needs.
Can I add my logo to a QR code?
Yes! Our QR code generator supports logo overlays. Upload your logo image, and it will be placed in the center of the QR code. We recommend using high error correction levels (Q or H) when adding logos to ensure the QR code remains scannable. Keep logos small (max 30% of QR code size) for best results.
What is error correction level and which should I use?
Error correction level determines how much damage a QR code can withstand and still be readable. Levels range from L (Low, 7% recovery) to H (High, 30% recovery). Use L for simple QR codes, M for general use, Q when adding logos, and H for maximum durability or when the QR code might be damaged.
What file formats can I download QR codes in?
You can download QR codes in three formats: PNG (raster image, good for web and general use), SVG (vector format, perfect for scaling and print), and PDF (document format, ideal for professional printing). Choose the format that best suits your use case.
Is my data safe when using this QR code generator?
Absolutely! All QR code generation happens locally in your browser. Your data never leaves your device and is never uploaded to our servers, ensuring 100% privacy and security when you create QR codes online.
Can I create QR codes on my phone?
Yes! Our QR code generator is fully mobile-responsive and works on smartphones, tablets, and desktop computers. You can create QR codes on your phone, customize them, and download them directly to your device.
What size should my QR code be?
QR code size depends on your use case: 128-256px for digital use (websites, emails), 256-512px for print materials (business cards, flyers), and 512-1024px for large format printing (posters, banners). Larger QR codes are easier to scan from a distance.
Can I customize QR code colors?
Yes! You can customize both the foreground (QR code pattern) and background colors. However, ensure there's sufficient contrast between colors for the QR code to be scannable. Traditional black on white works best, but you can use brand colors as long as contrast is maintained.
How do I test if my QR code works?
After generating your QR code, use your phone's camera app or a QR code scanner app to test it. Most modern smartphones have built-in QR code scanning in their camera apps. Test with multiple devices to ensure compatibility before printing or sharing.
