QR Code Generator
Generate QR codes with custom size, colors, and error correction level.
About This Tool
QR Code Generator is a free online tool that creates QR codes for any URL, text, email, phone number, or Wi-Fi credential — customized with your choice of color, size, and error correction level. Download the result as a PNG file ready for print, digital display, or embedding in documents. No account required, all generation runs in your browser.
QR codes are generated using qrcode.js, a reliable JavaScript library that produces standard QR code matrices at your specified size. Custom foreground and background colors let you match your brand or design. Four error correction levels (L, M, Q, H) let you trade code density for damage tolerance — important for physical print applications where the code may get scratched or dirty.
QR Code Generator is used by marketers adding QR codes to print materials and packaging, event organizers linking to registration pages, restaurant owners creating contactless menus, and developers creating QR codes for app deep links, authentication flows, or Wi-Fi sharing.

What can I encode in a QR code?
URLs, text, email addresses, phone numbers, Wi-Fi credentials, and any other text data.
What is error correction?
Error correction allows QR codes to be read even if partially damaged. Higher levels (H) allow more damage but create denser codes.
What error correction level should I choose?
L (7%) is fine for clean digital displays. M (15%) is suitable for most print use. Q (25%) and H (30%) are recommended for QR codes that will be printed on physical materials, stickers, or outdoor signage.
Can I create a QR code for Wi-Fi?
Yes. Enter your Wi-Fi credentials in the format: WIFI:S:NetworkName;T:WPA;P:Password;; and the QR code will allow phones to connect directly when scanned.
Is there a data size limit?
QR codes can hold up to about 4,296 alphanumeric characters or 2,953 bytes. For practical use, shorter data (URLs under 100 characters) produces cleaner, easier-to-scan codes.
