About This Tool
QR codes are everywhere: restaurant menus, event tickets, product packaging, business cards, payment systems. Generating one no longer requires specialized software — SiteConversor creates them in seconds, directly in your browser.
A QR code is a two-dimensional barcode encoding data in a matrix of squares. Unlike traditional barcodes that only encode numbers, QR codes store URLs, contact info, plain text, Wi-Fi credentials, and virtually any string up to ~2,000 characters. Modern smartphones scan them directly through the camera app.
Our generator uses QRCode.js, an open-source library creating codes entirely in your browser. Custom foreground and background colors let you integrate QR codes into brand materials — keep high contrast for reliable scanning by all cameras.
The generated PNG is 300×300px — sufficient for digital use and prints up to 5×5 cm at 300 DPI. For larger prints, scale up in any image editor; QR code geometry scales well.
Frequently Asked Questions
What can I encode in a QR code? expand_more
Any text up to ~2,000 characters. Common uses: website URLs, plain text, email (mailto:), phone (tel:), SMS (smsto:), and Wi-Fi credentials (WIFI: format).
Do QR codes expire? expand_more
No. QR codes from SiteConversor are direct encodings with no redirect service and no expiry. As long as the encoded URL or content is valid, the QR code works forever.
What size should I print my QR code? expand_more
For close-range scanning, minimum 2×2 cm. For signage viewed from 3 meters, use at least 8×8 cm. Always include a quiet zone (white border) of at least 4 modules on all sides.
Why is my QR code not scanning? expand_more
Common causes: insufficient white border, too-small print size, low-contrast colors, or URL too long. Try higher contrast, larger size, or shorten the URL first.

Yes. QR code is an open standard (ISO 18004) with no licensing fees for generating or using QR codes commercially.
