Browser-side. Your URL stays put.
'Offline QR generator' is a fuzzy term. Truly air-gapped tools require downloading software. Most web-based 'offline' tools still send your URL to their server for processing. The middle ground — generation that happens entirely in your browser, no URL ever transmitted — is rarer than you'd think.
Honest framing: QRThis is a web app, so the page itself loads from our server. But once loaded, static QR generation happens entirely in your browser's JavaScript — the URL you encode is processed client-side and never sent back to us. For most users worried about 'offline,' this client-side processing is what they actually want.
