About this generator

This generator composes a GS1 Digital Link URI from your inputs and renders the QR using the same single-path Zint pipeline that powers Closient's production QR generation. The output is identical to what your packaging would carry.

Want to make sure it's GS1-spec-compliant before printing? Run it through the QR Inspector for the full per-module breakdown.

Built by Closient — generate, audit, and resolve thousands of these at scale.
