About QR code generation
QR codes are 2D barcodes that can encode anything from a URL to a Wi-Fi password to a contact card. They've outlasted three generations of mobile platforms because they're free, open, and self-correcting: even partially damaged codes still scan thanks to Reed-Solomon error correction.
The Qaynaq Labs QR generator builds codes in your browser — no upload, no usage limit, no watermark. Pick an error correction level (higher levels stay readable after damage but make the code denser), choose colors, and export as SVG (infinite scaling) or PNG (universal compatibility).
Frequently asked
Are there any usage limits?
None. The code is generated locally; we don't see what you encode and don't track per-user usage.
Why pick a higher error correction level?
Higher levels (Q, H) survive partial damage — useful for printed codes that may get scratched. Lower levels (L) encode more data in a smaller code, useful for short URLs on tight packaging.
Will the colors I pick stay scannable?
Most contrast-respecting colors work. Light text on a dark background may need a contrast ratio of ~3:1 minimum — test with your phone before printing at scale.
Can I encode Wi-Fi or a vCard?
Yes — use the standard formats: <code>WIFI:T:WPA;S:NetworkName;P:password;;</code> for Wi-Fi, <code>BEGIN:VCARD\nVERSION:3.0\n...</code> for vCards.
