QR Code Generator
A QR code generator creates two-dimensional barcodes from text or URLs that smartphones can scan. QR codes are used everywhere from restaurant menus to business cards. Generate codes for URLs, text, phone numbers, SMS, email, and WiFi credentials. Download as PNG image for printing or sharing. Everything is generated client-side with no server uploads. The generator encodes data using QR code standards with error correction. It converts input text into a matrix of black and white modules. Error correction allows scanning even when partially damaged. The tool renders the QR code to a canvas element and exports as PNG. Different error correction levels balance density with durability. Business cards with contact information. Restaurant menu QR codes. Event tickets and registration. Product packaging with links to manuals. WiFi credential sharing. Payment links. Marketing materials with campaign tracking URLs. Educational materials linking to online resources. Test your QR code before printing in bulk. Use higher error correction for codes that may be partially obscured. Ensure sufficient contrast between modules and background. Include a URL shortener for cleaner codes. Place codes where they are easily scannable at a reasonable distance. Related tools: Password Generator, Random Number Generator, UUID Generator, Random Color Generator, Raffle / Picker Wheel.
