Free Online QR Code Generator with Logo & Gradients

Looking for a way to create a free QR code that looks exactly the way you imagine? You’ve just found the safest and most advanced tool on the internet. Forget boring black and white squares. With our editor, you can generate stylish QR codes with your logo, colors, and modern gradients – all without registration and completely free.

Why is this QR generator unique? (Client-Side Technology)

Most online generators send your data to external servers, where the QR code is processed and sent back. We do it differently. Our tool is built on modern technology that runs directly in your browser.

What does this mean for you?

  • 100% Security and Privacy: Whether you’re entering a web link, sensitive text, or a Wi-Fi password, this data will never leave your computer. No server sees, stores, or tracks it.
  • Instant Speed: You don’t wait for a server response. Generation happens in real-time right before your eyes.
  • Works even offline: Once the page loads, you can generate more codes even in offline mode.

Custom Design: Gradients, Rainbow, and Custom Colors

A QR code is part of your branding. That’s why we give you absolute freedom in how it looks. Our editor offers features that are often paid for elsewhere:

1. Advanced Rendering Styles

Tired of solid colors? Revitalize your code! Choose from several visual styles:

  • Linear gradient: A smooth transition between two colors (e.g., from dark blue to light), which looks clean and professional.
  • Radial gradient: An effect where color radiates from the center outwards, giving the code spatial depth.
  • Rainbow: Want to catch attention at first glance? Use our special rainbow effect for a playful and unmissable design.

2. Custom Colors and Backgrounds

Do you have specific corporate colors? No problem. You can enter exact HEX codes (e.g., #9933FF) for both the foreground and background of the QR code. The tool automatically checks contrast to ensure the code remains easily scannable.

Add credibility to your code. Simply upload your company or brand icon directly into the center of the QR code. Thanks to adjustable error correction (up to 30%), the code remains fully functional even with an embedded image.

Guide: How to Create a QR Code in 3 Steps

Its operation is intuitive and easy for everyone:

  1. Enter Content: In the “Text or URL” field, type a web address (e.g., acrafto.com), a text message, or contact details.
  2. Customize Appearance:
    • Set the size in pixels (ideal for print and web).
    • Select “Render Style” – try a radial gradient, for example.
    • Choose colors that match your project.
  3. Download and Use: Click the “Download” button. Your QR code will be instantly saved to your device in high quality, ready for printing or sharing.

Where can you use our QR codes?

Static QR codes created here have unlimited validity. They are ideal for:

  • Marketing materials: Flyers, posters, billboards.
  • Business cards: Quick saving of contacts to a phone.
  • Restaurants and cafes: Contactless menus directly on the table.
  • Wi-Fi connection: Save guests the hassle of typing complex passwords.
  • Product packaging: Links to instructions, ingredients, or contests.

Frequently Asked Questions (FAQ)

Is this generator truly 100% free, even for commercial use? Yes, absolutely. Unlike "freemium" services that block your QR code after a week and demand payment, our tool is completely free. You can safely use the generated codes on corporate business cards, billboards, product packaging, or in television advertising. There are no limits on the number of scans or expiration dates.
Why is "Client-Side" generation safer than other tools? Most online generators send your data (URLs, texts, Wi-Fi passwords) to a remote server where the code is created. This poses a security risk. Our tool works differently – all calculations are performed using JavaScript directly in your browser. Data never leaves your computer. It's an ideal solution for generating QR codes with sensitive information, such as access credentials or internal company links.
Will my QR code stop working after some time? No, never. We generate so-called "static QR codes." The information is encoded directly into the graphic squares of the image. There is no redirection through our server that could expire. As long as the target website or text you embedded in the code exists, the QR code will function – even in 100 years.
How do I ensure a colored QR code with a gradient is scannable? The key is contrast. QR code readers need a clear difference between dark points (code) and a light background. Although our generator allows beautiful rainbow and gradient transitions, make sure the code color is sufficiently dark against the background. We recommend always performing a test scan with a mobile phone directly on the screen before printing the code.
I inserted a logo, but the code is not scannable. What should I do? If you use a logo in the center of the code, you need to increase the "Error Correction" level. In our tool, set the level to the highest possible (e.g., Q or H - 25-30%). QR code technology is designed to survive damage – high error correction adds redundant data to the code, so the scanner "reconstructs" the missing part covered by your logo.
What size (px) should I choose for printing on a large format? For the web, 250–500 px is sufficient. For printing (flyers, posters), the rule is: the more, the better. In our generator, enter a higher value (e.g., 1000 px or more) to ensure that the edges of the squares are sharp even when enlarged. A blurry QR code is difficult for scanners to focus on and can lead to malfunction.
Does the generator work without an internet connection (Offline)? Yes! Thanks to modern web architecture, after the first page load, the necessary scripts are cached in your browser. You can then open the site on your laptop, disconnect from Wi-Fi (for example, on a plane or train), and still generate dozens of codes. No data is sent, so the internet is not needed for the actual computation.
What is a "Radial gradient" and when should I use it? A radial gradient is an effect where color transitions from the center outwards, unlike a linear gradient, which goes from one side to another. This effect adds depth and a "glowing" look to the QR code. It's an excellent choice for technology companies or modern designs where you want to draw attention to the center of the code (for example, where your logo is).
