About the QR Code Generator
A QR (Quick Response) code is a two-dimensional barcode that stores data as a grid of black and white modules. Modern phone cameras scan them instantly to open URLs, show text, join Wi-Fi networks, and more. This generator encodes your content using the ISO/IEC 18004 standard with selectable error-correction levels (L, M, Q, H) that let the code stay readable even when partially obscured.
Error correction explained
Reed-Solomon error correction adds redundant data so the code can be read even if part of it is damaged or covered. Higher levels (Q, H) tolerate more damage but produce denser codes for the same data. For printed posters or labels, choose H; for digital display where the code is always clean, L or M is fine.
Exporting
Download as PNG for raster use (social, screens) or SVG for infinitely scalable vector use (print, logos). The quiet zone — the white margin around the code — is set to the standard 4 modules by default and can be adjusted for tight layouts.
