What Is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned with a smartphone camera or QR reader app, the encoded data is instantly decoded —opening a website, connecting to Wi-Fi, sending an email, or displaying text.

QR codes were invented in 1994 by Denso Wave for tracking automotive parts, but today they are used everywhere: restaurant menus, business cards, product packaging, event tickets, and marketing materials.

How to Create a QR Code for Free

Creating a QR code with Ercc is simple and free:

2. Enter your content in the appropriate tab.
3. Optionally customize colors, size, and error correction level.

QR Code Error Correction Levels

QR codes have built-in error correction that allows them to be scanned even if partially damaged or obscured:

Level	Recovery Capacity	Best For
L (Low)	~7% damage	Simple URLs, clean environments
M (Medium)	~15% damage	General use (recommended)
Q (Quartile)	~25% damage	Printed materials, outdoor use
H (High)	~30% damage	QR codes with logos overlaid

FAQ

Frequently Asked Questions

How do I create a QR code for free?

Enter your text, URL, or Wi-Fi details into Ercc's QR Code Generator and click Generate. Your QR code is created instantly in your browser. You can customize the colors and size, then download it as a PNG image. No signup or payment required.

What can I encode in a QR code?

You can encode any text, website URLs, Wi-Fi network credentials (SSID and password), email addresses, phone numbers, and more. QR codes can hold up to about 4,296 alphanumeric characters.

Can I customize the color of my QR code?

Yes! Ercc lets you choose custom foreground and background colors for your QR code. Make sure there is enough contrast between the two colors so the QR code remains scannable.

Do the QR codes expire?

No. QR codes generated by Ercc are static codes —the data is encoded directly in the image. They never expire and will work forever as long as the encoded content (like a URL) is still valid.

Is this QR code generator really free?

Yes, 100% free with no limits. There is no watermark, no signup, no ads, and no restrictions on how many QR codes you can generate. Everything runs locally in your browser —your data is never sent to any server.
