What is the QR Code Generator?

A QR code (Quick Response code) is a two-dimensional barcode that stores data — a URL, text, contact details, Wi-Fi credentials, or anything else — in a format readable by smartphone cameras and QR scanner apps. The QR Code Generator creates QR codes for any content you provide, instantly and for free.


How to Use the QR Code Generator

  1. Enter your content. Type or paste the data you want to encode — a URL, plain text, phone number, email address, or any other string.
  2. Customize if needed. Adjust the size and error correction level to suit your use case.
  3. Generate. The QR code is created instantly as you type.
  4. Download. Save the QR code as a PNG image, ready for print or digital use.

What You Can Encode

URLs — the most common use. Anyone who scans the code is taken directly to the URL in their browser. Shorten long URLs first to keep the QR code less dense and more scannable.

Plain text — the scanner displays the text directly. Useful for encoding instructions, codes, or any short message.

Email addresses — scanning opens a new email composition window addressed to the specified address.

Phone numbers — scanning prompts the phone to call or save the number.

SMS — scanning opens a pre-addressed text message.

Wi-Fi credentials — scanning connects the device to the Wi-Fi network automatically. The SSID and password are encoded in a standard format that iOS and Android recognize natively.

vCard contact info — scanning saves a contact directly to the phone's address book, including name, phone, email, company, and website.


Error Correction Levels

QR codes include redundant data that allows them to be read even when partially obscured, damaged, or printed at low resolution. Four levels are available:

Level Recovery capacity Use when
L (Low) ~7% Clean digital display, small file size
M (Medium) ~15% General use, good balance
Q (Quartile) ~25% Logo overlay, some wear expected
H (High) ~30% Heavy use, rough conditions, logo overlay

Higher error correction produces a denser QR code that requires more pixels to scan reliably. For print materials, M or Q is recommended. For adding a logo over the center of the QR code, use H.


Practical Tips

Test before printing. Scan the QR code on at least two different devices before committing to a print run. Test under the lighting conditions where it will be used.

Minimum size for print: 2×2 cm. Below this, scanning becomes unreliable. For business cards, 2.5×2.5 cm is safer.

Use UTM parameters for tracking. Append ?utm_source=print&utm_medium=flyer to your URL to track how many visitors came from each QR code placement in Google Analytics.


Privacy

QR code generation happens entirely in your browser. No content encoded or QR codes generated are sent to any server.
