Frequently Asked Questions
What kinds of data can I encode in a QR code?
You can encode almost any textual dataset. Our generator features specific presets to format data patterns for URLs (web addresses), plain text paragraphs, Wi-Fi credentials (allowing users to scan to connect to a network), and email messages (formatting recipients, subjects, and bodies automatically).
How do the QR code size and error correction levels work?
QR codes use Reed-Solomon error correction to recover data if the code is dirty or damaged. The levels range from L (7% recovery) to H (30% recovery). Higher error correction makes the QR code denser but ensures it remains readable when printed on textures, vehicles, or physical cards.
Are the generated QR codes free to use commercially?
Yes, all QR codes generated via NexToolkit are 100% free, static QR codes. They contain the raw data itself (no redirect links or intermediate tracking URLs), meaning they will never expire and can be used without royalties for commercial printing, packaging, and advertising.
