How to Generate a QR Code for Free — URLs, vCards, WiFi, PIX

QR codes went from "novelty bar trick" to "the way you share anything in the physical world" in a couple of years. Here's how to generate one in under 30 seconds — for free, with no signup.

Pick the right content type

Most QR generators force everything through a URL. XGuardia's QR Code Generator gives you five purpose-built types:

• URL: the most common — link to a website, landing page, or social profile
• Plain text: any string up to ~2,000 characters
• vCard (Pro): contact card that auto-imports name, phone, email when scanned
• WiFi (Pro): network name + password, scans connect automatically on iPhone/Android
• PIX (Pro): Brazilian payment QR with key, recipient name, optional amount

For most cases, URL is what you want. The richer types are gold for in-person networking and events.

Step-by-step

1. Open the QR Code Generator
2. Pick a content type
3. Fill in the form — live preview updates as you type
4. On Pro: customize foreground/background colors, error correction, and embed a logo
5. Click Download PNG or Copy data URL

When to embed a logo

A centre logo makes a QR code more memorable and signals brand ownership. The tradeoff: it covers some of the data area, so you need higher error correction (level H, ~30% recoverable) to keep the code scannable.

The XGuardia generator nudges you to switch to H automatically when you upload a logo.

Print vs digital

For print: download at the largest size (the tool outputs 720×720 by default) and let the printer downscale. Never scale up a small QR — pixelation kills scanability.

For digital: the data URL works directly in CSS, emails, or HTML. Copy and paste — no file upload needed.

Privacy

QR generation runs 100% in your browser. We never see what URLs or content you're encoding.
