QR Code Generator

This QR Code Generator encodes URLs, plain text, WiFi logins, phone numbers and email addresses into a scannable QR code entirely inside your browser tab. As you type or paste, a JavaScript encoder rebuilds the code on every keystroke: it selects the tightest data mode (numeric, alphanumeric or byte), appends Reed-Solomon error-correction blocks at the level you choose, and paints the black-and-white modules onto an HTML canvas. Nothing you enter is uploaded, and there are no servers involved at all — the guest WiFi password you encode never leaves the machine you typed it on. That local-only design is the whole point when the data is a network key, a private phone number or an unpublished link.

You control the foreground and background colors, though scanners need a genuinely dark pattern on a light background to lock on. Export as PNG for screens, chat and social posts, or as SVG for anything that gets resized — business cards, roll-up banners, packaging, laser engraving — because vector paths stay sharp at any size instead of pixelating. No sign-up, no watermark burned across the image, no daily cap.

For WiFi, the tool assembles the standard WIFI:S:<name>;T:WPA;P:<password>;; string so a phone joins on one scan without anyone typing the key. Typical jobs: a cafe linking a digital menu, a host sharing tenant WiFi, a designer dropping a portfolio URL on a resume, an organizer encoding a venue map, a shop pointing to a review page.

A few things that actually change scan reliability: keep URLs short, because fewer characters mean fewer modules and an easier read from across a room — shorten long links first. Raise the error-correction level when the code will be printed small or might get scuffed, since higher redundancy lets a reader recover damaged modules. Leave a clear quiet-zone margin of blank space around the code. Avoid inverting to a light-on-dark pattern, which many older scanners reject. And always test the exported file on two or three phones before a large print run.
