Why generate QR codes in bulk, locally?

Bulk QR services usually want your whole product list, ticket database or URL set uploaded to their servers, and many wrap your links in tracking redirects that expire. Digital Heroes renders every code on your own device from your raw values: no tracking, no expiry, no account. You get plain PNG files in a ZIP, named by row, label or value, ready for print sheets, packaging or mail merges.
