Frequently Asked Questions
How do I create a QR code for free?
Enter your URL, text, or data in the input field above and a QR code is generated instantly. Click "Download PNG" to save the image. This generator is completely free — no signup, no watermark, no limits. The QR code is created in your browser using JavaScript, so your data is never sent to any server.
What is the difference between static and dynamic QR codes?
Static QR codes encode data directly in the pattern — the destination can never change, but they work forever. Dynamic QR codes encode a redirect URL that can be updated later, allowing destination changes without reprinting. This tool generates static QR codes. Dynamic QR codes require a server-side redirect service (usually paid).
Do QR codes expire?
Static QR codes never expire — the data is encoded directly in the visual pattern and will scan correctly forever, as long as the encoded URL or content remains accessible. Dynamic QR codes can expire if the redirect service subscription lapses. All QR codes from this tool are static and permanent.
How much data can a QR code store?
QR codes can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data (at the lowest error correction level, L). In practice, keep data under 300 characters for reliable scanning — longer data creates denser QR patterns that are harder for phone cameras to read, especially at small print sizes.
How do I create a WiFi QR code?
Click the "WiFi" tab above, enter your network name (SSID), password, and select the encryption type (WPA/WPA2 for most networks). The tool generates a QR code in the standard format: WIFI:T:WPA;S:NetworkName;P:Password;;. When scanned with a phone camera, it automatically offers to connect to the network — no manual typing needed.
