What Is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can store text, URLs, contact information, and other data. Scan it with a smartphone camera and you instantly access the stored content — no typing needed.
Compared to traditional barcodes, QR codes hold far more data (up to 4,296 characters), read faster, and can still be decoded even when partially damaged thanks to built-in error correction.
Common Uses for QR Codes
Website links: Turn a URL into a QR code to print on business cards, posters, or packaging — letting people visit your site by scanning
Wi-Fi access: Encode your Wi-Fi credentials into a QR code so guests can connect automatically without typing a password
Contact information: Package your name, phone number, and email as a vCard QR code — scan to save the contact instantly
Payments: Mobile payment systems like Apple Pay and Google Pay use QR codes for contactless transactions
Product traceability: Food, medicine, and other products use QR codes to let consumers check origin and ingredients
Event check-in: Turn a ticket or invitation into a QR code for fast, scannable entry
Enter your content — Type or paste a URL, text, or any other data into the input field
Preview in real time — The QR code generates as you type. Scan it with your phone to verify it works
Download — Choose PNG (for most uses) or SVG (for scalable printing) and download
PNG vs SVG: Which Format to Download
PNG: The right choice for most cases — works in web pages, presentations, Word documents, and social media. Download at least 500×500px for print use
SVG: A vector format that scales to any size without losing quality. Ideal for large-format printing like banners and billboards, or embedding directly in code
Tips for a High-Quality QR Code
Keep content short: The more data stored, the denser the QR code and the harder it is to scan. Use a URL shortener for long links
Maintain quiet zone: Leave adequate white space around the QR code — without it, scanners may fail to read it
Test on multiple devices: After generating, scan with both iOS and Android to confirm it works correctly
Minimum print size: Print QR codes at least 2×2 cm (about 0.8×0.8 inches) for reliable scanning
Frequently Asked Questions
Do QR codes expire?
No. QR codes generated with tool.tl are static — the data is encoded directly in the image pattern, with no server dependency. As long as the image exists, the QR code works permanently.
Can I add a logo to the QR code?
QR codes have built-in error correction, meaning they can still be read even if part of the image is covered. In design tools like Canva or Photoshop, you can overlay a logo in the center — just keep it under 30% of the total QR code area.
iPhone users can point the built-in Camera app at a QR code and tap the notification that appears. Android users can use the Camera app or Google Lens. Most messaging apps (WhatsApp, WeChat) also have built-in QR scanners.
