Business card QR codes need to be small, reliable, and scannable at arm's length. Use a short URL (ideally under 50 characters), pick a clean black-on-white design, and download at 300px or higher for crisp printing.
QR code generated locally using qrcode. All processing runs in your browser.
The short URL you paste (a portfolio link, LinkedIn profile, or vCard page) is sent through the qrcode library locally so the smallest possible QR symbol is selected, ideal for a 1.5 cm card slot. The library renders the matrix to a Canvas for a sharp 300px PNG and exports the same matrix as SVG so your printer can scale it to any card stock without losing fidelity.
All QR code generation happens locally in your browser tab. Our servers are not involved at any point.
To create 1D barcodes for products and labels, try the barcode generator. For reading codes back from a picture, use the QR code scanner. To percent-encode URLs before embedding them, see URL encode.
Your website, LinkedIn profile, or a digital contact page (vCard) are the most common choices. Keep the URL as short as possible, shorter URLs produce simpler, more reliable QR codes.
Download the SVG version for the sharpest print quality. SVG is resolution-independent and will look perfect at any print size. PNG at 300px or above works too.
A minimum size of 1.5 cm × 1.5 cm is workable for business cards at close range. Keep the URL short to reduce QR density, use standard black-on-white colors, and use error correction level M.
