QR Code Generator – Generate QR Online (Free Tool)

QR Code Generator turns any text, URL, contact card, or Wi-Fi credential into a scannable QR code. The image is generated locally using the standard QR algorithm (ISO/IEC 18004), so your data — even sensitive items like Wi-Fi passwords — never leaves the browser. Download as PNG at the size you need.

• Touch-friendly UI, fine on phones for on-the-go edits

• Handles UTF-8 BOM, mixed delimiters, and other edge cases that break simpler converters

• Print materials (business cards, flyers, posters, restaurant menus)
• Wi-Fi sharing at home, in shops, and at events
• Linking from physical signage to a digital landing page
• Embedding contact info in resumes or email signatures
• Tracking conversions by generating unique UTM-tagged URLs per campaign

QR scans but to the wrong URL.

Check the input — extra spaces, missing https://, or unescaped special characters can change the encoded text. Use the higher error-correction level if the medium might be damaged.

QR is unscannable at small sizes.

Increase size to at least 256px when displayed on screens, or 2cm × 2cm when printed. Raise error correction to Q or H if the medium may be obscured.

Generator fails for very long input.

QR codes have a max capacity (~4000 alphanumeric chars at L correction). Shorten the URL (use a URL shortener) or split the content across multiple codes.
