What Can You Put Inside a QR Code?
A modern QR code can store more than just a URL. REXAI's generator supports seven types:
Website URLs — link to your homepage, a landing page, a product, or a specific post. WiFi networks — let guests connect by scanning once, no typing passwords. Contact cards (vCard) — share your name, phone, email, company, and website so clients save your details with one tap. Email addresses — pre-fill the recipient, subject, and message. Phone numbers — start a call with one scan. SMS messages — pre-fill text and recipient. Plain text — share any short message or note.
How to Create a QR Code Online
You don't need design software or technical knowledge. The whole process takes under two minutes.
1. Choose your QR code type. Decide what you want the scanner to see — a URL, WiFi, contact card, email, phone, SMS, or plain text. Each type has its own input form.
2. Enter your information. For a URL code, paste the full link including https://. For WiFi, enter the network name (SSID), password, and security type (WPA/WPA2 or open). For a business card, add your name, phone, email, company, and website.
3. Customize the design. Adjust the foreground color, background color, size, and margins. Add your logo if you want a branded look. The live preview updates as you change settings.
4. Test before publishing. Scan the code with your own phone. Try a second phone if possible. Test it from the distance your audience will actually scan it from — a code that works on-screen may fail once printed at a smaller size.
5. Download the file. Choose PNG for websites, social media, presentations, and digital documents. Choose SVG for print — because SVG is vector, it stays sharp at any size, from a business card to a billboard.
Static vs Dynamic QR Codes
Before you create a QR code for a long-term campaign, understand the difference.
Static QR codes store their data directly inside the code. Once printed, the destination cannot be changed without creating a new code. This makes them perfect for permanent information — a WiFi password, a fixed contact card, a stable website URL, or a menu that won't change.
Dynamic QR codes use a redirect link between the printed code and the destination. You can update the destination anytime without reprinting the code. This is ideal for marketing campaigns, seasonal promotions, or anything that might change. If you printed thousands of flyers pointing to a QR code and want to redirect them next quarter, a dynamic code lets you do it without wasting the flyers.
How Businesses and Freelancers Use QR Codes
QR codes solve real problems across many industries.
Restaurants — replace printed menus with a QR code on each table. Update the menu anytime, add new items, change prices — no reprinting cost. Retail and e-commerce — put a QR code on packaging that opens a product page, warranty registration, or a related product. Freelancers — print a QR code on business cards that opens your portfolio, LinkedIn, or a contact form. Clients save your details with one tap. Event organizers — use QR codes for check-in, schedule downloads, session links, or post-event surveys. Real estate agents — put a QR code on "For Sale" signs that opens a virtual tour, listing page, or direct call.
Tips for a Scannable Custom QR Code
Design matters — but function matters more. A code that looks beautiful but doesn't scan is useless. Follow these guidelines:
Keep strong contrast. The QR pattern must stand out clearly from the background. Dark pattern on light background is safest. Avoid low-contrast pairs like yellow on white. Don't cover too much with a logo. A small logo in the center works fine thanks to built-in error correction. Cover more than 30% and the code stops working. Leave quiet space. The blank margin around the code helps scanners find it — don't let other design elements crowd it. Match size to scanning distance. A code scanned from 2 meters should be at least 20cm wide. Always test before printing.
Why Choose REXAI's QR Code Generator?
Most QR code tools either water-mark the output, cap free scans, or expire your codes after a trial period. REXAI's generator doesn't. You get unlimited free static QR codes, full customization (colors, logo, size, margins), and download in both PNG and SVG — with no signup, no ads, and no expiration date.
Everything runs in your browser. Your data never leaves your device, and no third-party server tracks your scans.
