Our "QR Code Generator" is a completely free, registration-free web application that instantly converts URLs and text into scannable QR codes. In today's smartphone-centric world, asking users to manually type a long or complex URL is impractical. With this tool, you can effortlessly convert website links, contact information, and Wi-Fi credentials into a format that anyone can scan using their camera. In addition to standard black-and-white QR codes, you can customize the design by placing a company logo or icon in the center and adjusting the colors to match your brand. Create original, practical, and visually appealing QR codes intuitively right from your browser.

✓ Tool Features

  • Completely Free with No Limits: This tool requires no account registration or login. You can use all features immediately just by accessing the site. There are no strict limits on the number of QR codes you can generate or the amount of text you can input. Whether you need to create multiple QR codes for business use or convert long messages, you can use it freely without worrying about extra fees.
  • Intuitive Real-Time Preview: Whenever you input text or change color settings, the final QR code is instantly updated in the preview area. This eliminates the frustration of not knowing what the generated image will look like until you download it, allowing you to create the perfect QR code smoothly while checking color balance and design.
  • Advanced Customization (Colors & Icons): Beyond simple black-and-white codes, our color customization feature lets you freely set the foreground and background colors. By utilizing advanced error correction, you can also place custom images, company logos, or social media icons right in the center of the QR code. This helps differentiate your brand and instantly communicates to users where the code will lead them.
  • Flexible Size & Error Correction Settings: Easily select the right output size from a dropdown menu, ranging from small sizes for websites to high-resolution formats for printed materials like business cards and posters. You can also fine-tune the "Error Correction Level" in four stages to ensure the QR code remains scannable even if slightly damaged. When you upload an icon, the tool intelligently selects the optimal level (H) automatically, ensuring a foolproof experience even without technical knowledge.

Detailed Usage & Tips

  1. Enter Text or URL
    Enter the website URL, email address, or any text you want to convert into the input area. The QR code will be automatically generated and displayed in the preview area instantly. Because a longer text means denser dots—requiring a higher resolution to scan—we recommend using a URL shortener first if your URL is exceptionally long. This results in a cleaner, more easily recognizable QR code.
  2. Customize the Design (Colors & Icon)
    While checking the preview, adjust the foreground and background colors in the customization section. You can intuitively pick your brand colors using the color picker. To ensure the code can be reliably scanned by smartphone cameras, it is crucial to maintain high contrast between the background and the QR code itself (e.g., a light background with a dark code). If you wish to center a logo, select an image file in the "Icon Image" section. The icon size is automatically adjusted to the optimal ratio to prevent scanning errors.
  3. Set Image Size and Download
    Once your design is complete, choose the output size in the "Size & Error Correction" section. For print uses such as business cards or flyers, we strongly recommend selecting a larger size (800px or more) to prevent the image from blurring when scaled. Finally, click the download button at the bottom of the screen to save your QR code in your preferred format (PNG or JPEG). You can then paste the saved image directly into Word, Excel, or any design software.

Built for Security and Privacy

Our QR Code Generator utilizes modern web technologies, primarily JavaScript, to perform all image generation processes entirely within your browser (locally on your computer or smartphone). Thanks to this advanced local processing, sensitive URLs, customer data entered into the text box, and uploaded company logo files are never transmitted to external servers or stored in our databases.

As a result, the risk of data leaks and unauthorized access is fundamentally eliminated. You can safely and confidently use this tool for business purposes with strict security requirements or for converting private contact information.

Recommended Use Cases

Printed Materials (Business Cards, Flyers)

Printing a QR code on your business card that links to your company site or personal portfolio saves the recipient the hassle of typing out the URL, encouraging smooth access. Placing a QR code on restaurant or retail flyers for LINE friend additions or discount coupons seamlessly guides customers from offline print media to online engagement, significantly boosting your marketing conversion rates.

Supplementary Materials in Presentations

During seminars or internal meetings, you can embed QR codes linking to survey forms or detailed PDF downloads directly onto your presentation slides. Attendees can quickly scan the QR code displayed on the screen with their smartphones to retrieve information without disrupting the flow of the meeting. This enhances participant engagement and facilitates a more interactive presentation experience.

Frequently Asked Questions (FAQ)

Can I use the generated QR codes for commercial purposes (e.g., product packaging, advertising)?
Yes. QR codes created with this tool can be used for commercial purposes completely free of charge, whether by individuals or corporations. Feel free to use them on product packaging, TV or magazine advertisements, store signages, and menus without any restrictions. There are no obligations for credit notation or linking back to our site.
My smartphone is having trouble scanning the QR code. How can I fix this?
The most common cause of scanning issues is a lack of contrast between the background and the QR code itself. Try setting the QR code to a darker color and the background to a lighter, white-based color. Scanning can also be difficult if the center icon is too large or if the URL is too long, causing the dots to become too fine. Try setting the "Error Correction Level" to the maximum "H" or generating a larger output size.
Do the QR codes expire? Will the links disappear later?
The QR codes generated by this tool do not have any expiration dates or time limits. The URL or text data you enter is directly encoded as an image (dot pattern), meaning it can be scanned semi-permanently. However, please note that while the QR code itself will continue to work, if the destination website is closed or the URL changes, users will no longer be able to access the link.
What is the difference between Error Correction Levels L, M, Q, and H? Which should I choose?
Error correction indicates the QR code's ability to restore data and be scanned correctly even if parts of it are hidden, dirty, or damaged. There are four levels: L (~7% recovery), M (~15% recovery), Q (~25% recovery), and H (~30% recovery). A higher level provides better resistance to damage but results in a denser, more complex dot pattern. The default "M" is sufficient for standard use. However, if you are placing an icon in the center or using the code outdoors where it might get dirty, we highly recommend selecting the strongest level, "H".
