QR Code Generator

The QR Code Generator is a free QR code generator that turns any URL or block of text into a scannable code the instant you finish typing, with no server round-trip and no delay. It's built for anyone who needs to create a QR code fast — marketers linking print flyers to a landing page, restaurant owners publishing a digital menu, event organizers building check-in passes, or a developer who just needs a quick code to test a mobile deep link. Choose an output size from 128 to 1024 pixels and download the result as a PNG with no watermark baked in.

Real-world use goes well beyond plain links: paste a phone number as `tel:+15551234567` to make a code that opens the dialer, a `WIFI:T:WPA;S:name;P:password;;` string to let guests join a network with one scan, or a vCard block to hand out digital business cards. Because every modern phone camera reads QR codes natively, there's no app for the person scanning to install — the code just has to be printed or displayed clearly.

Under the hood, generation and rendering both happen locally in your browser — the tool encodes your content directly into the QR matrix and draws it to a canvas, so there's no third-party redirect or shortener service that could go offline, start charging, or track scans later. You can also choose an error-correction level (Low, Medium, Quartile or High); higher levels rebuild the code from less surviving data, which matters if you're printing small, laminating, or expect the code to get scuffed, at the cost of a denser pattern.

One caveat worth knowing before you print: very long input strings (long URLs with tracking parameters, full vCards) produce a denser, harder-to-scan pattern, so it helps to shorten the URL first if you're printing small. Always test a printed code with a real phone camera at the intended size before running a full print job — a code that renders perfectly on screen can still be too dense to scan reliably at 1.5 cm on a business card.
