QR Code Settings
QR Code Size
The size affects scanning quality and usability.
Size | Recommended Use |
|---|---|
200–300 px | Websites, user interfaces |
400–800 px | Documents and PDFs |
1000+ px | Print materials, banners |
For printing, it is recommended to use higher-resolution QR codes.
Error Correction
QR codes support built-in damage recovery.
Level | Recovery Capacity | Recommended Use |
|---|---|---|
L | 7% | Maximum compactness |
M | 15% | Standard option |
Q | 25% | Colored QR codes and logos |
H | 30% | Printing and complex designs |
The higher the error correction level, the larger and denser the QR code becomes.
Common Mistakes
Using a QR code that is too small: Small QR codes can be difficult to scan, especially when printed.
Low contrast: A light-colored QR code on a light background may not be recognized by cameras.
Encoding too much data: Large amounts of text make QR codes denser and harder to scan.
Using very long URLs: Long links increase QR code complexity. Consider using a URL shortener when appropriate.
Skipping testing: Always test your QR code on multiple devices before publishing.
Practical Recommendations
Use high-resolution PNG files for printing
Test QR codes on both iOS and Android devices
Use error correction level H for logos and colored QR codes
Avoid placing QR codes too close to layout edges
Leave a “quiet zone” (white space) around the QR code
A quiet zone is the empty space surrounding a QR code that is required for proper recognition by cameras and QR scanners.

Frequently Asked Questions (FAQ)
You can encode various data types, including URLs, plain text, contact information (vCard), Wi-Fi credentials, email addresses, phone numbers, SMS messages, and much more.
QR codes can store up to 4296 alphanumeric characters, 7089 numeric characters, or 2953 bytes of binary data. However, the more data you include, the denser and harder to scan the code becomes.
Yes, you can customize colors, add logos, change module shape, and adjust the error correction level. However, ensure sufficient contrast between foreground and background for reliable scanning.
The minimum recommended size is 2x2 cm (0.8x0.8 inches) for close-range scanning. For long-distance scanning, use larger sizes. A rule of thumb: scanning distance = QR code size × 10.
Common issues include insufficient contrast, too much or too little data, poor print quality, damaged code, or inadequate lighting. Ensure good contrast, test before mass printing, and include error correction.
Error correction allows QR codes to be readable even if partially damaged. There are four error correction levels (L, M, Q, H), where H provides the most redundancy (up to 30% damage).
The generator creates static QR codes. This means the data in the code is fixed at the time of creation and cannot be changed later. If you need to update the content, you must generate a new QR code. However, if the QR code contains an encrypted link to your website or landing page, you can update the information on the page itself without changing the QR code. The main thing is to maintain the same URL so the code continues to point to the current content.
The QR code itself is just a data format. Security depends on the encoded content. Be cautious when scanning codes from unknown sources, as they may lead to malicious websites or unwanted content.
