What can I encode in a QR code?

URLs, plain text, WiFi credentials, phone numbers, and email addresses.

Can I change the size?

Yes. Use the size slider to adjust from 128px to 512px before downloading.

Are QR codes permanent?

Static QR codes like these are permanent and never expire.

Why won't my QR code scan?

The most common causes are the code being cropped too tightly (no blank margin around it), printed too small, or low print contrast. Always test-scan with a real phone before printing at scale.

Can I add a logo in the middle of the QR code?

QR codes have built-in error correction that tolerates some damage or obstruction, which is what allows a small logo in the center — but always test the scan afterward to confirm it still works.

How It Works

QR codes encode text, links, or contact data into a scannable grid of black-and-white squares, with built-in error correction so the code still scans even if part of it is damaged, dirty, or covered by a logo.

What's actually inside the code

The QR standard supports several data types with specific formats — for example, WiFi credentials are encoded as `WIFI:S:<name>;T:WPA;P:<password>;;` so a phone camera recognizes it as a network to join rather than plain text. This tool builds the correct format automatically based on whether you're encoding a URL, plain text, WiFi, phone number, or email.

Error correction and size

QR codes include redundant data so a scanner can still read them even if up to roughly 30% of the code is damaged (at the highest error-correction level) — this is what allows logos to be placed in the center of some QR codes without breaking the scan. Larger pixel sizes and higher contrast improve scan reliability, especially for print.

Examples

Restaurant menu QR code

Encode your menu's URL, generate at 512px for crisp printing on a table tent, and test-scan it with two different phone models before printing in bulk.

WiFi sharing for guests

Encode your WiFi network name and password once, print the QR code, and guests can join by scanning instead of typing a long password character by character.

Common Use Cases

Printing menus, business cards, or posters that link to a website without typing a URL
Sharing WiFi access with guests or at events without reading out a password
Linking print advertising or packaging to a product page, video, or contact form
Sharing contact details (phone/email) that save directly to a scanner's phone

Tips

Always test-scan a generated QR code with an actual phone camera before printing at scale — screen glare, print resolution, or an unusually small size can all cause scan failures that aren't obvious on-screen.
Leave a visible quiet zone (blank margin) around the QR code — cropping it too tightly is one of the most common reasons a otherwise-valid code fails to scan.
If you'll need to update the destination later (e.g. a changing menu or promotion), point the QR code at a URL you control rather than encoding the final content directly, since a static QR code's data can't be edited after printing.
