How to Generate a Free QR Code (WiFi, Links, Text & More)

Published September 2, 2026 · 4 min read · By Files Craft Editorial Team

QR codes have gone from a niche marketing gimmick to something almost everyone scans weekly — restaurant menus, WiFi passwords, event check-ins, payment links. Making your own takes about 10 seconds and doesn't require any design skill.

What Can You Put in a QR Code?

  • A website link: The most common use — sends scanners straight to any landing page, menu, or portal.
  • WiFi credentials: Guests scan and connect automatically without typing long, complex passwords.
  • Plain text: Instructions, serial numbers, codes, or short reference notes.
  • Contact info (vCard): Scan-to-save a name, phone number, email, and address directly to phone contacts.
  • Email or phone number: Opens a pre-filled email draft or phone dialer automatically.

How to Create a QR Code

  1. Open the free QR code generator.
  2. Choose what type of content you're encoding (link, text, WiFi, etc.).
  3. Enter your details or network password.
  4. Download the high-resolution generated QR code as an image, ready to print or embed.

Tips for QR Codes That Actually Scan Well

  • Keep the encoded content short: Longer URLs create a denser matrix that is harder for phone cameras to focus on.
  • Leave a quiet border (margin): Don't crop right up against the pixel edges when placing the code in print materials.
  • Test print size: A code that looks crisp on a monitor might be too small on a business card; test scan a physical printout first.
  • Maintain high contrast: A dark code on a crisp white background scans far more reliably than pastel or low-contrast gradients.

A Related Small Tool: Favicons

If you're building out branding assets alongside a QR code — say, for a small business or event page — you might also need a favicon for your website's browser tab icon, which is another simple one-click task.

Frequently Asked Questions

A standard QR code generated this way doesn't expire — it's a fixed mathematical pattern encoding your content directly, not a tracked link. It will only stop working if the destination link itself (e.g. a website) is taken down.

Yes, this is a common and safe use case for guest WiFi. Just be mindful of where you display the printed code, since anyone who scans it will be able to connect to that network.

QR codes can technically hold a few thousand characters, but practically, shorter content produces a cleaner, more reliably scannable code — especially important if it will be printed small.
