QR Code Generator

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. Smartphones and tablets can scan QR codes instantly with their cameras, making them a fast way to share links, information, or actions without typing.

QR codes were invented in 1994 and have become widely used for sharing website links, connecting to Wi-Fi, making payments, accessing menus, sharing contact details, and more. They can store considerably more data than traditional barcodes and can be scanned even if partially damaged.

What Does This Tool Do?

This tool generates a QR code from any text or URL you provide. The QR code is created instantly in your browser and can be downloaded as an image file to use anywhere — print it, embed it in a document, or share it digitally.

How to Use This Tool

1. Type or paste your text or URL into the input field.
2. The QR code is generated instantly.
3. Download the QR code as a PNG image using the download button.

Common Use Cases

• Sharing links: Create a QR code for a URL to print on flyers, posters, or business cards.
• Restaurant menus: Link to a digital menu without requiring customers to type a URL.
• Business cards: Add a QR code that opens your website or LinkedIn profile.
• Events: Share event details, registration links, or Wi-Fi passwords as QR codes.
• Retail: Link product packaging to manuals, videos, or support pages.

Beyond URLs: Special QR Content Formats

A QR code can trigger specific actions if the text follows a recognized format:

Paste any of these into the input and the resulting code will trigger the corresponding action when scanned — most phone cameras recognize them natively.

Tips for QR Codes That Actually Scan

• Keep content short. More characters means denser modules. A URL shortener can turn a 120-character link into a much simpler, more scannable code.
• Maintain the quiet zone. The white margin around the code is required by the spec — don’t crop it or place the code flush against other graphics.
• Contrast matters. Dark modules on a light background scan best. Avoid light-on-dark inversions and low-contrast brand colors for print.
• Size for distance. Rule of thumb: minimum scan size ≈ scanning distance ÷ 10. A poster scanned from 1 meter needs a code at least 10 cm wide.
• Always test before printing. Scan the final artwork with more than one phone — what works on a screen can fail on paper.

What Makes QR Codes Resilient

QR codes include Reed–Solomon error correction, which stores redundant data so the code still scans when partially damaged or obscured. There are four levels: L (~7% recoverable), M (~15%), Q (~25%), and H (~30%). Higher correction makes the code denser but more robust — level H is what allows logos to be placed over the center of a code without breaking it.
