How It Works: From Idea to Scanned Code in Under 60 Seconds
Choose Your QR Code Type
Select from 20+ QR code types in our visual selector. Need a website link? Choose URL. Sharing WiFi? Choose WiFi for automatic connection. Creating a digital business card? Choose vCard to add contact details directly to phone address books. Promoting an Instagram profile? Choose Instagram for direct profile links. Accepting payments? Choose Payment for PayPal, Venmo, or cryptocurrency addresses. Each type is optimized for its specific use case with smart form fields that guide you through entering the correct information. Not sure which type you need? Our tooltips and descriptions explain each option.
Enter Your Content
Fill in the type-specific form with your information. For URL codes, paste your website link (we automatically validate formatting and add https:// if missing). For WiFi codes, enter network name (SSID), password, and security type (WPA/WEP/None) — guests will auto-connect when scanning. For vCard codes, add your name, phone, email, company, and address — recipients can save you as a contact with one tap. For social media codes, enter your username or profile URL. For event codes, add title, date, time, and location. Each form is designed to be intuitive with placeholder examples and validation to ensure your QR code works perfectly on first try.
Customize Your Design
Match your brand with complete visual customization. Upload your company logo to the center (automatic error correction ensures scannability even with logo overlaid). Choose foreground and background colors from our color picker or use pre-tested color presets (dark red on white, navy on cream, black on light blue) that guarantee scannability. Select dot pattern style: Squares (classic, highest compatibility), Dots/Circles (modern friendly look), or Fluid (organic rounded design). Customize the three corner eye frames with 8 unique styles from angular to circular. Add a frame with custom text like 'SCAN ME' or 'VIEW MENU' to increase scan rates. Use our one-click design templates for professionally designed color palettes and patterns. Preview updates in real-time as you customize.
Download & Use
Download your QR code in your preferred format. PNG (high resolution, 1024×1024+) is perfect for digital use — email signatures, websites, social media posts, PowerPoint presentations, and small print items. SVG (vector format) is essential for professional printing — scales infinitely without quality loss, ideal for billboards, posters, banners, T-shirts, and vehicle wraps. PDF combines convenience with compatibility for easy sharing with print shops or clients. For static codes (permanent, no tracking), you're done — download and use immediately. For dynamic codes (editable with analytics), click 'Make Dynamic' to create a dashboard entry where you can edit the destination URL anytime, track scans with detailed analytics, and manage all your codes in one place. Always test your QR code by scanning with multiple devices (iPhone and Android) before mass printing to ensure reliability.
QR Code Best Practices: Ensure 100% Scannability
Size Matters: Use the 10:1 Rule
QR codes must be large enough for camera sensors to resolve individual pixels. Use the 10:1 ratio rule: scanning distance (inches) ÷ 10 = minimum QR code size (inches). Examples: business cards scanned from 6-10 inches need minimum 0.8-1 inch codes (2-2.5cm), flyers and posters scanned from 12-24 inches need 1.5-2.5 inches, restaurant table tents scanned from 10-20 inches need 1.5-2.5 inches, billboards scanned from 10-20 feet need 10-18 inches, product packaging varies by size but handheld products need 0.8-1.5 inches. Absolute minimum regardless of use case: never go below 2cm × 2cm (0.8 inches). Below this threshold, most phone cameras cannot resolve pixels reliably. When in doubt, go larger — oversized codes are never a problem, undersized codes always are.
Contrast Is King: Dark on Light Always Wins
QR scanners detect patterns by identifying light/dark differences. High contrast is non-negotiable. Best practice: black foreground on white background (95%+ scan reliability across all devices and lighting conditions). Safe alternatives: dark navy on white, dark red on white, black on light yellow, forest green on cream. Dangerous combinations that often fail: yellow on white (insufficient luminance difference), dark blue on black (no contrast), orange on yellow (too similar), red on green (fails for colorblind users and often lacks contrast). Inverted codes (white on black) can work but test extensively — older phone cameras (pre-2018) struggle with inversion. To test contrast: convert your QR code to grayscale; if foreground and background look too similar in grayscale, they lack sufficient contrast. Always prioritize scannability over aesthetics — a working black-and-white code is infinitely better than a beautiful non-scanning colored one.
Test Before Printing: The 10-Minute Check That Saves Thousands
Never print 1,000 copies without testing. Follow this pre-print checklist: (1) Test on multiple devices — scan with both iPhone (native Camera app) and Android (Camera or Google Lens) to ensure cross-platform compatibility. Test with older devices too if your audience includes them. (2) Test at actual print size — resize your digital proof to exact dimensions you'll print and scan from expected distance. If users scan from 10 inches, test from 10 inches. (3) Test lighting conditions — scan in bright light, dim light, and with glare on the surface to simulate real-world usage. Matte finishes scan more reliably than glossy. (4) Test color combinations — if using brand colors, verify they provide enough differentiation in various lighting. (5) Verify the destination — make sure the URL loads, WiFi credentials connect properly, vCard imports all fields correctly, payment links work, etc. (6) Print a small test batch (10-50 copies) on the actual material (paper, sticker, plastic, fabric, metal) you'll use for production before full run. Different materials affect scannability. This 10-minute process can save thousands in reprinting costs.
Leave the Quiet Zone: White Space Is Required, Not Optional
The quiet zone is the white margin around your QR code — it's not decorative, it's required by ISO specifications. This clear space helps scanners identify where the QR code begins and ends, especially on busy backgrounds with text or images. Minimum required: 4 modules (4 times the width of one QR code dot) on all four sides. Our default is 10 modules for extra safety margin. When you can reduce: if your QR code is on a plain white page with no nearby elements, you can reduce to 4-6 modules to save space. When you should increase: if the code is on a colorful poster with text and images nearby, increase to 15-20 modules for clear visual separation. Common mistake: placing text, borders, logos, or design elements right up against QR code edges — this causes scan failures. Always leave breathing room. To verify: export as SVG, measure one module (single dot width) in design software, and confirm margin is at least 4 modules wide on all sides. This ensures compliance with ISO/IEC 18004 standard and maximum reliability across all scanning apps.
Choose the Right Format: PNG for Digital, SVG for Print
Download format matters for final quality. PNG (Portable Network Graphics) is a raster/bitmap format — composed of pixels. Use PNG for: websites and landing pages, email signatures, social media posts (Instagram, Facebook, LinkedIn), PowerPoint or Keynote presentations, digital documents (PDFs, Word docs), and small print items (business cards, flyers) where you control exact size. Always download at least 1024×1024 resolution (higher for large prints) and ensure 300 DPI when printing. SVG (Scalable Vector Graphics) is a vector format — composed of mathematical paths, not pixels. Use SVG for: professional printing at any size (billboards, posters, banners), merchandise (T-shirts, mugs, hats, bags), vehicle wraps and decals, large-format signage, architectural applications, and any situation where final size is unknown or variable. SVG scales infinitely without quality loss — a 1-inch code and 10-foot code have identical clarity. Design software (Adobe Illustrator, Figma, Canva Pro) and professional print shops handle SVG perfectly. PDF combines both: use for easy sharing with clients or print shops who may not have design software, universal compatibility across devices, and 'ready to print' packages. Pro tip: for professional projects, download all three formats — PNG for quick digital sharing, SVG for print production flexibility, PDF for client presentations.
Logo Size: Sweet Spot Is 15-20% of Total Area
Logos enhance branding and increase scan trust (users are more likely to scan branded codes than anonymous ones), but size matters for scannability. QR codes use error correction to remain functional even when partially covered — up to 30% of the code can be damaged or occluded and it still scans. However, real-world reliability drops sharply above 25% logo coverage. Recommended size: 15-20% of total QR code area (our interface shows percentage). This balances branding visibility with scan reliability. Safe maximum: 25% — above this, scan failures become common, especially in poor lighting or with low-contrast QR colors. Danger zone: 30%+ — high failure rate. Avoid unless you're using perfect conditions (black on white code, bright even lighting, large print size, high-end phone cameras). Always set error correction to High (30% redundancy) when adding a logo — our system does this automatically. Test logo-bearing codes extensively before production: scan with multiple phones, various lighting conditions, from expected distance, and with both iOS and Android. Logo shape matters: circular logos are most efficient (waste least QR code area), square logos are second-best, horizontal or vertical rectangular logos can block entire rows of data modules (less efficient). Alternative approach: place logo outside the QR code (next to or above/below) to guarantee 100% scannability while maintaining branding. Add a frame with your brand name for similar branding effect without scannability risk.
Frequently Asked Questions About Creating QR Codes
Is the QR code generator really free? Are there hidden costs?
Yes, completely free with no hidden costs, trials, or paywalls. All features including dynamic QR codes, scan analytics, logo upload, custom colors, and unlimited scans are free forever. No credit card required at any point. You can create unlimited static codes as a guest or sign up (free, email only) to access dynamic code management and analytics. We believe in open access to technology — QR codes should be available to everyone, from individuals to small businesses to large enterprises.
What's the difference between static and dynamic QR codes?
Static codes embed data directly in the pixels — truly permanent, fastest scanning (no server lookup), complete privacy (no tracking possible), but uneditable once created. If the URL breaks or you want to change it, you must regenerate and reprint. Use static for WiFi codes, permanent labels, or when privacy is critical. Dynamic codes store a short redirect URL pointing to our servers. Scanning routes through QR-Verse to your destination. This enables: editing destination anytime without reprinting, real-time scan analytics (location, device, browser, time), A/B testing capability, and dashboard management. Both are free forever with unlimited scans on QR-Verse.
Can I add my company logo to the QR code?
Absolutely. Upload your logo (PNG, JPG, or SVG formats) and it's automatically centered with error correction to maintain scannability. Recommended logo size is 15-20% of total QR code area (our interface shows percentage). Larger logos may cause scan failures, especially in poor lighting. We automatically set error correction to High (30% redundancy) when you add a logo, allowing the code to scan even with logo overlay. Always test logo-bearing codes with multiple devices before mass printing.
What download formats are available and which should I use?
We offer PNG (high resolution raster, 1024×1024+), SVG (scalable vector format), and PDF (universal compatibility). Use PNG for: websites, email signatures, social media, digital documents, and small print items (business cards, flyers) at 300+ DPI. Use SVG for: professional printing at any size, billboards, posters, merchandise (T-shirts, mugs), vehicle wraps, and situations where final size is variable. SVG scales infinitely without quality loss. Use PDF for: easy sharing with print shops or clients, universal cross-device compatibility. Pro tip: download all three formats for maximum flexibility.
Do I need an account to create QR codes?
No account needed for static QR codes — start creating immediately as a guest. For dynamic QR codes (editable with scan analytics), you need a free account with just an email address. No phone number or credit card required. Once logged in, you can claim any anonymous codes you created as a guest and manage them from your dashboard. Creating an account takes under 30 seconds and unlocks powerful features like editing destinations, tracking scans, running A/B tests, and organizing all codes in one place.
How many QR codes can I create? Are there limits?
Unlimited. Create as many QR codes as you need — static or dynamic, with no caps, quotas, or throttling. All codes include unlimited scans forever. No expiration dates, no degradation over time. Whether you need 10 codes or 10,000, QR-Verse scales with your needs.
