How this calculator works
A QR code generator turns any text or link into a square barcode your phone camera can read in a fraction of a second. Type or paste into the box above and the code renders instantly: every phone made in the last decade scans it with the stock camera app, no special software needed. The most common use is links - menus, portfolios, event pages, WiFi portals - but QR codes hold any short text: a discount code, an app-store URL, a Bitcoin address, or a whole contact card.
Two controls separate a good generator from a toy. Error correction decides how much of the code can be damaged or covered and still scan: Medium (15%) is the everyday default, while High and Highest survive printed wear, stickers, and even a small logo placed in the center. Download size matters for print: 256 px is fine on screen, 512 px suits flyers, and 1024 px stays crisp on posters and signage. The SVG download is vector, so it scales to any size with zero blur - the right choice for professional print.
Everything happens locally in your browser: the QR image is computed on your device, nothing you encode is sent to a server, and there is no account, watermark, or scan limit. That also means the code never expires and never phones home to a tracking service, unlike some "free" generators that route scans through their own servers. For WiFi sharing specifically, the dedicated WiFi QR Generator builds the special WIFI: payload and even prints a ready-to-hang guest sign.
