QR Code Generator

A QR code is just a short piece of text that a camera can read, and almost every one you meet is a link. What changes between them is the format of that text: a Wi-Fi code is not a link at all, and a contact card is a small structured document. This generator writes each of those formats correctly so the code does what a scanner expects rather than opening a page full of raw text.

The formats worth being careful about are Wi-Fi and contact cards, because both are delimiter-separated. A password containing a semicolon, or a company name containing a comma, will quietly truncate the payload unless it is escaped — producing a code that scans successfully into the wrong thing, which is far more confusing than one that fails outright. Every value you type is escaped for the format it lands in.

Error correction decides how much of the code can be damaged or covered and still read. Low recovers about 7%, high about 30%. Higher correction makes the code physically denser, so it needs to be printed larger; for a sticker that might get scuffed, or a code with a logo placed over the middle, the extra redundancy is worth the size.

You can recolour the code, and the tool will warn you when the two colours are too close together. This is the most common reason a customised QR code fails in the real world: it still looks perfectly good on a screen, but a phone camera in ordinary light cannot separate the dark modules from the background. Dark on light, with real contrast, always scans best — and inverting it to light-on-dark defeats many scanners entirely.

Download as PNG for screens and social posts, or as SVG for anything that will be printed. SVG is made of shapes rather than pixels, so it stays perfectly sharp whether it ends up on a business card or a billboard. Everything is generated in your browser, so the link, the network password or the contact details you type never reach a server — and unlike most free generators, the code has no expiry date and no tracking redirect in the middle.
