What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can store URLs, text, contact info, WiFi credentials, and more. You can scan it with any smartphone camera to instantly access the encoded information.
Is this QR code generator completely free?
Yes, this QR code generator is 100% free with no limitations. No registration, no watermarks, no usage limits. Create as many QR codes as you need.
What types of QR codes can I create?
You can create QR codes for URLs/websites, plain text, email addresses (mailto), phone numbers (tel), SMS messages, WiFi network credentials, and vCard/digital business cards.
Can I customize the colors of my QR code?
Yes, you can customize both the foreground (modules) and background colors. For best scanning results, ensure high contrast between the dark modules and light background.
Can I change the size of the QR code?
Yes, you can adjust the output size in pixels. Larger sizes are better for print, while smaller sizes work well for screens and digital use.
Is my data safe and private?
Absolutely. All QR code generation happens entirely in your browser using JavaScript. No data is sent to any server, and nothing is stored or logged anywhere.
Do QR codes expire?
No, static QR codes never expire. Once generated, the QR code will work forever as long as the destination (e.g., the URL) remains active.
How do I scan a QR code?
Simply open your smartphone's camera app and point it at the QR code. Most modern phones (iOS and Android) will automatically detect and decode it, offering a tap-to-open link.
Can I download the QR code as an image?
Yes, you can download your generated QR code as a PNG image. It's ready to use in print materials, presentations, websites, or social media.
What is the minimum scan distance for a QR code?
The scan distance depends on the QR code size and the version (data density). As a rule of thumb, the code should be at least 1/10th of the scanning distance.
Can I use QR codes for my business?
Absolutely! QR codes are widely used for business cards, product packaging, restaurant menus, event tickets, marketing campaigns, and contactless payments.
Does this tool work offline?
Yes, once the page is loaded, QR code generation works entirely offline in your browser. No internet connection is needed after the initial page load.
How to Use QR Code Generator
Generate QR codes for URLs, WiFi logins, contacts and more — entirely in your browser, so the data you encode never leaves your device.
- Choose what to encode from the "Data Type" dropdown: URL, Text, Email, Phone, SMS, WiFi or vCard, then fill in the fields that appear.
- Pick the export resolution under "Size" (128x128 up to 1024x1024) and the error-correction level under "Correction".
- Adjust the colors with "Foreground" and "Background", or load a small picture via "Logo Image (Optional)" and "Choose Image...".
- Press "Generate QR Code" and scan the preview with your phone camera to confirm it reads correctly.
- Save it with "Download PNG" or place it on the clipboard via "Copy Image"; "Reset All" clears every field.
A higher error-correction level in "Correction" keeps the code scannable even when the logo covers part of it.
