QR Code Generator

Enter a link or Wi-Fi details to see a QR code preview right away, then save it as PNG or SVG.

🔒 The link and Wi-Fi password you enter are never sent to a server. The QR code is made only in your browser.

QR code type
If you leave out https://, it is added for you.
Appearance
Higher levels resist damage better but hold less content.

Your QR code appears here as you type.

Scan it once with your phone camera before using or printing it. It may not read on every device or print.

How to use

  1. Choose the kind of QR code: link (URL) or Wi-Fi.
  2. For a link, enter the address (https:// is added if you leave it out). For Wi-Fi, enter the network name (SSID), password and security type, and tick the box if the network is hidden.
  3. If needed, change the foreground and background colours, the saved size (256, 512 or 1024px) and the error correction level (default M). A warning appears when the contrast is low.
  4. Check the preview and press [Save PNG] or [Save SVG]. Scan it once with your phone camera before you use it.

Supported formats, limits and privacy

  • Links must be http:// or https:// web addresses. Other formats such as phone, SMS or email are not supported.
  • The maximum content (UTF-8 bytes) depends on the error correction level: L 2,953 · M 2,331 · Q 1,663 · H 1,273 bytes. Non-Latin characters take 2 to 4 bytes each. Longer content makes a denser pattern that is harder to read when printed small.
  • The Wi-Fi name (SSID) can be at most 32 bytes. Wi-Fi QR codes use the widely used WIFI: format (security WPA/WPA2/WPA3, WEP or none), and the special characters \ ; , : " are escaped as the format requires. Enterprise (802.1X) authentication is not supported.
  • The saved size is 256, 512 or 1024px. Each module is a whole number of pixels and the rest becomes margin (at least 4 modules). SVG stays sharp at any size.
  • Whether a code scans depends on the phone, camera app, print quality and colour contrast. This tool does not guarantee that it reads everywhere, so scan it yourself before sharing or printing.
  • The link and Wi-Fi details you enter are turned into a QR code only inside this browser. They are not sent to a server or stored, and they disappear when you close the page.

Frequently asked questions

Does scanning a Wi-Fi QR code connect right away?

Most recent phones ask whether to join the network when the built-in camera reads a Wi-Fi QR code. Support still depends on the model, operating system version and camera app, and older devices may need a separate app.

Which error correction level should I choose?

Higher levels (L → M → Q → H) are more likely to read when part of the code is covered or dirty, but the same content makes a denser pattern and less content fits. The default M is enough for screens and clean prints. Consider Q or H for stickers and other places where the code may get damaged.

Do these QR codes expire?

This tool makes static QR codes that hold the link or Wi-Fi details directly, so they have no expiry and do not go through any server. If the linked page disappears or you change the Wi-Fi password, make a new QR code.
