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. HeroTools 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.
