How to Create a QR Code for Different Purposes
A QR code can make it easier to share information without requiring people to type long addresses or search for details manually. The right content depends on what you want people to access when they scan the code.
1. Create a QR Code for a Website
Choose Website URL and enter the web address you want to share. You can enter a complete address or a domain name. If the address does not include a protocol, the generator automatically adds HTTPS. Always test the destination before distributing the QR code.
2. Create a QR Code for Plain Text
Select Plain Text and enter the information you want to share. This option is useful for short instructions, messages, reference information and other text that does not require an internet connection to read after scanning.
3. Create a Wi-Fi QR Code
Select Wi-Fi Network and enter the network name (SSID). Choose the appropriate security type and enter the password when required. A compatible smartphone can scan the code and offer to connect to the network.
For an open network, select the option that indicates no password. Remember that anyone who can scan a protected Wi-Fi QR code may be able to access the encoded network credentials.
4. Create an Email QR Code
Choose Email and enter the destination email address. You can also add an optional subject and message. When scanned, a compatible device can open its email application with the information prepared.
5. Create a Phone QR Code
Select Phone Number and enter the number using the appropriate country code when necessary. Scanning the code allows a compatible smartphone to recognize the number and offer a calling option.
Review Before Downloading
After entering your information, choose the image size, quiet zone and error correction level. Generate the code, scan it with a smartphone and confirm that the information is correct before printing or sharing it.
Choosing the Right QR Code Settings
The quality and readability of a QR code depend on more than the information it contains. Choosing appropriate image size, quiet zone and error correction settings can help make your code easier to scan across different devices and situations.
1. Choose the Image Size
Image size determines the pixel dimensions of your downloaded QR code. This tool offers three options:
- 256 × 256 pixels: Suitable for small digital uses and quick sharing.
- 512 × 512 pixels: A balanced option for everyday digital use and many printing situations.
- 1024 × 1024 pixels: Provides more image resolution for larger layouts and print materials.
A larger image does not automatically make a QR code easier to scan. The physical printing size, contrast, data density and print quality also matter.
2. Understand the Quiet Zone
The quiet zone is the empty space surrounding a QR code. It separates the code from nearby text, images and other visual elements, helping scanning devices identify its boundaries.
- Compact: Uses a smaller surrounding margin when space is limited.
- Standard: Provides a balanced margin for general use.
- Large: Adds more empty space around the code, which can be useful in visually busy layouts.
Avoid placing text, borders or decorative elements too close to the QR code. When in doubt, use the Standard or Large setting and test the result.
3. Select the Error Correction Level
Error correction allows a QR code to remain readable even when part of its data becomes damaged or obscured. Higher correction levels provide greater recovery capability, but they also reduce the amount of information that can fit into the code.
- Low (L): Suitable when the code is expected to remain clean and unobstructed.
- Medium (M): A balanced choice for many everyday applications.
- Quartile (Q): Provides stronger error recovery for situations where additional protection is useful.
- High (H): Offers the greatest error recovery capability among the available options.
Higher error correction does not guarantee successful scanning. The QR code must still have sufficient contrast, appropriate dimensions and a clear surrounding area.
Which Settings Should You Use?
For most everyday applications, 512 × 512 pixels, a Standard quiet zone and Medium error correction provide a practical starting point. For printed materials or more demanding environments, test different settings before producing large quantities.
Always scan the downloaded image using a smartphone before printing or distributing it. If possible, test it at the actual size and distance at which people will scan it.
How to Test and Print QR Codes
Generating a QR code is only the first step. Before sharing it online or adding it to printed materials, test the code to make sure it can be scanned easily and displays the intended information.
1. Test the QR Code After Generating It
Use a smartphone camera or a compatible QR code reader to scan the downloaded image. Check that the code opens the correct website, displays the expected text or performs the intended action.
- Confirm that the destination or encoded information is correct.
- Test the code on more than one smartphone when possible.
- Check that website links load successfully.
- For Wi-Fi codes, confirm that the device recognizes the network details.
- Repeat the test after making any changes to the design or layout.
2. Use Sufficient Contrast
QR codes need a clear visual difference between the dark modules and the light background. High contrast generally makes the code easier for scanning devices to recognize.
Avoid low-contrast color combinations, transparent backgrounds over complex images and patterns that interfere with the code. A dark code on a light, uniform background is a reliable choice.
3. Choose an Appropriate Printing Size
The best physical size depends on the amount of information encoded, the density of the QR code and the distance from which people will scan it. A more complex code may require more space to remain readable.
Do not assume that a 1024-pixel image must be printed larger than a 512-pixel image. Pixel dimensions describe image resolution, while physical print dimensions depend on the printing layout and output resolution.
4. Keep the Quiet Zone Clear
Leave enough empty space around the QR code. Do not place text, logos, borders or decorative elements too close to its edges. The surrounding area helps scanning devices identify the code correctly.
5. Avoid Common Printing Problems
- Do not stretch, compress or distort the QR code.
- Avoid blurry or pixelated images.
- Do not cover important parts of the code with logos or graphics.
- Avoid glossy reflections that make scanning difficult.
- Check that the printed code is not cropped or partially hidden.
- Test the final printed version, not only the original digital image.
6. Test at the Actual Scanning Distance
A QR code that works on a computer screen may behave differently when printed on a small label, a business card or a large poster. Test it at the actual size and viewing distance expected in its final location.
For materials produced in large quantities, print and test a sample first. This simple step can help prevent costly reprints and inaccessible QR codes.
Final Checklist Before Sharing
- The QR code opens or displays the correct information.
- The code has sufficient contrast and a clear quiet zone.
- The image is not distorted or cropped.
- The printed size is appropriate for the scanning distance.
- The final printed or displayed version has been tested.
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. It can be scanned using a smartphone camera or a compatible QR code reader.
QR codes can contain website addresses, plain text, contact information, Wi-Fi network details and other types of data.
Understanding Static QR Codes
A static QR code stores its information directly inside the code itself. When someone scans it, the encoded data is read by the scanning device without requiring an external QR redirection service.
How Do Static QR Codes Work?
When you create a static QR code, the selected information is converted into a pattern of black and white modules. This pattern contains the data that a compatible device reads when scanning the code.
For example, a website QR code stores the web address itself. A Wi-Fi QR code stores the network information needed by a compatible device to recognize the connection details.
Static QR Codes vs. Dynamic QR Codes
Static and dynamic QR codes are different in how they handle information and destinations.
- Static QR codes: Store the actual information inside the code. Once generated, the encoded content cannot be edited. To change it, you must generate a new QR code.
- Dynamic QR codes: Typically store a short redirect address that points to information managed by an external service. This can allow the destination to be changed without replacing the printed code, depending on the provider.
Do Static QR Codes Expire?
Static QR codes do not have an automatic expiration date. The encoded information remains in the code as long as the image is preserved and can be scanned.
However, the destination itself may change or become unavailable. For example, a website can be removed, a web address can stop working or a Wi-Fi password can be changed.
Advantages of Static QR Codes
- No subscription or QR redirection service is required.
- The encoded information is stored directly in the code.
- They can be scanned without an internet connection when the encoded information is usable offline.
- They are suitable for permanent information that does not need frequent updates.
- They can be downloaded and used in digital or printed materials.
Limitations to Consider
- The encoded information cannot be edited after generation.
- A new code is required whenever the information changes.
- Website QR codes still depend on the destination website being available.
- Static codes do not provide built-in scan analytics or tracking.
When Should You Use a Static QR Code?
Static QR codes are a practical choice for website addresses, Wi-Fi access, contact details, short instructions and other information that is expected to remain unchanged.
If you need to update destinations frequently or monitor scan activity, a dynamic QR code service may be more appropriate. Consider any subscription costs and provider requirements before choosing one.
The HARTI TOOLS QR Code Generator creates static QR codes. Your information is encoded directly into the generated image, giving you a simple way to share it without depending on a QR redirection platform.
Where can you use QR codes?

Your Privacy and Security Matter
The HARTI TOOLS QR Code Generator processes the information you enter directly in your browser. The QR code is generated on your device, and the content you provide is not submitted to a HARTI TOOLS server for QR code creation.
How Your Information Is Processed
The generator uses a JavaScript QR code library loaded from the jsDelivr content delivery network (CDN). This library runs in your browser to create the QR code.
The information entered into the generator is processed locally by the tool. However, loading the external library requires a connection to the CDN. This is why an internet connection is needed when opening the online generator.
Be Careful With Sensitive Information
A QR code stores the information encoded during its creation. Anyone who can scan the code may be able to access that information, depending on its content and the scanning device.
- Avoid encoding passwords, personal identification numbers or confidential business information.
- Remember that Wi-Fi QR codes contain network credentials when a password is required.
- Share QR code images only with people who should have access to the encoded information.
- If a Wi-Fi password becomes exposed, consider changing the network password.
Stay Safe When Scanning QR Codes
Not every QR code is trustworthy. A code displayed in a public place, received in a message or found on printed material may lead to an unexpected or fraudulent website.
- Check the destination address before opening a link.
- Be cautious with websites requesting passwords or payment details.
- Do not download files or install applications from untrusted destinations.
- Use the same care with QR codes as you would with ordinary web links.
What Happens to Your Generated QR Code?
The generated QR code is displayed in your browser and can be downloaded as a PNG or SVG file. This tool does not provide a cloud storage account or a QR code management dashboard.
