🔳 QR Code Generator

This free QR code generator turns any URL or block of text into a scannable QR code you can download as a PNG image. Whether you need a quick QR code maker for a business card, a poster link, a Wi-Fi password, or any other short piece of text, this tool generates it instantly in your browser with no signup and no watermark.

How It Works

Type or paste your text or URL into the box, choose an output size (from 200x200 up to 500x500) and an error-correction level, then click Generate QR Code. The QR code is rendered directly onto a canvas using the open-source qrcode.js library, entirely on your device — nothing you type is sent to a server. Once generated, the Download PNG button saves the image so you can use it in a document, print it, or share it online.

Why It Matters

QR codes bridge the gap between print and digital — a menu, flyer, product label, or business card can link straight to a website, contact card, or Wi-Fi network with a single phone scan. Generating your own QR code online, for free, and entirely client-side means you don't have to trust a third-party service with the destination URL or text, and you're not limited by a paid plan's usage cap.

Tips for Accurate Results

• Test your generated QR code with a couple of different phone cameras before printing it at scale, especially for small or low-contrast prints.
• Use a higher error-correction level (Q or H) if the code will be printed small, placed on a curved or textured surface, or have a logo overlaid on top.
• Keep the encoded text as short as practical — very long text creates a denser, harder-to-scan pattern, especially at smaller sizes.
• Choose a larger size (400x400 or 500x500) for anything that will be scanned from a distance, like a poster or storefront sign.
