A practical guide
A vCard QR code bundles contact fields instead of sending the scanner to a contact website. Start with a full name, then add the fields you actually want to share: given and family names, company, job title, international phone number, email address, website and address. The generator creates a vCard 3.0 record with the required name and version properties. Reserved characters are escaped, lines use CRLF and long lines are folded without splitting UTF-8 characters.
Contact data grows quickly. A detailed address, long company name or several optional fields can make the QR much denser than a single URL. Increase the export size when necessary, or omit information that is not needed on the card. A phone's contact importer determines how fields are displayed and whether the person must approve the import. Test Chinese names and addresses with the devices used by your audience. A QR contact card is not private: anyone with the image can extract the details, and updating your contact record does not update older printed cards.
Your inputs, styling and logo are processed in this browser. Generating a code does not upload them or contact the encoded destination. There is no account, saved history, QR tracking service or subscription. Loading this website still requests its static files from the host; opening a link after scanning is a separate action that can contact another service. Clearing the workspace removes its current content and image references, but does not promise a forensic wipe of browser memory or files you already downloaded.
Choose among PNG, SVG, JPEG and WebP in the export panel. JPEG cannot carry a transparent background and uses white instead. Use a clear, non-sensitive filename and keep the downloaded image somewhere appropriate for its content. The export button generates the latest revision directly; a separate preview click is not required. A local decode check compares the downloaded design with the encoded bytes. If it fails, the tool stops rather than silently shortening the content or lowering error correction.
Before distributing or printing, scan the actual exported file with a phone your audience uses. Verify both its content and the intended action. Scanning conventions and application behavior can differ, and a successful software decode is not a universal camera guarantee. Retain enough surrounding space, use a light background and keep a copy of the source details so you can regenerate a static code when those details change.
