QR Code Generator Free
Generate QR codes from text or URL. Choose size and colors. Live preview, download PNG. In the browser, no server.
Why use a QR code generator
QR codes let you share a link or short text that anyone can scan with a phone camera. Generating them in the browser means your content never leaves your device.
This tool uses the qrcode library: you paste a URL or type up to 500 characters, choose size (128, 256, or 512 px), and optionally set the QR and background colors. The preview updates live. You download a PNG image.
Use it for flyers, business cards, or any place you need a scannable code. Ensure good contrast (e.g. dark on light) so scanners can read it.
Frequently asked questions
- How do I generate a QR code online?
- Enter your text or URL in the text area (up to 500 characters). Choose size (128, 256, or 512 px) and optionally the QR and background colors. The preview updates live. Click "Download PNG" to save the image.
- Are my data sent to a server?
- No. The QR code is generated entirely in your browser. Your text or URL never leaves your device.
- What can I put in a QR code?
- You can encode plain text, URLs, email addresses, phone numbers, or any short text up to 500 characters. For very long content, consider using a URL shortener first.
- What size should I choose?
- 128 px is good for small prints or thumbnails. 256 px is a good default for screens and medium prints. 512 px is best for large prints or high resolution.
- Can I change the colors?
- Yes. Use the color pickers to set the QR module color (default black) and the background color (default white). Ensure good contrast so scanners can read the code.
- Does it work on mobile?
- Yes. Open the tool in your mobile browser, enter text, adjust options, and download the PNG. No app install required.
- Is there a character limit?
- Yes, 500 characters. Longer content may not fit in a standard QR code or may require a larger symbol. For URLs, use a short link if needed.
- Why is my QR code hard to scan?
- Use high contrast (e.g. black on white). Avoid very small sizes or low resolution. Ensure the printed or displayed image is not blurred or distorted.
- Can I use the QR code commercially?
- The tool generates a standard QR code image. Usage rights depend on your content (e.g. URL or text you encode). The QR code itself is just a representation of that content.
- Does it work in all browsers?
- Yes. Any modern browser that supports Canvas (Chrome, Firefox, Safari, Edge) can run this tool.
