QR Code Generator

Yes, this QR code generator is completely free to use. There are no usage limits, watermarks, or sign-ups required. All generation happens locally in your browser.

Absolutely. All QR code generation is performed locally in your browser. Your URLs, contact details, WiFi passwords, and any other data never leave your device. No data is transmitted to any server.

You can generate QR codes for URLs, plain text, email addresses (with subject and body), phone numbers, SMS messages, WiFi network credentials (including password and security type), and vCard contact information.

Error correction allows a QR code to be read even if part of it is damaged or obscured. Level L (~7%) is suitable for clean, high-quality printing. Level M (~15%) is the default and works for most use cases. Level Q (~25%) and H (~30%) are ideal for harsh environments or when you plan to add a logo in the center of the QR code.

Yes. You can set custom foreground (dark module) and background (light module) colors using the color pickers. Keep in mind that high contrast between the two colors is essential for reliable scanning. Very light foregrounds or very dark backgrounds may make the code unscannable.

You can download your QR code as a PNG image (raster, good for digital use and small print) or as an SVG file (vector, infinitely scalable and ideal for large-format printing like posters and banners).

For digital screens, 256×256 pixels is usually sufficient. For print, a general rule is that the QR code should be at least 2×2 cm (about 0.8 inches) when viewed from a standard distance. Use 512×512 or 1024×1024 for larger formats like posters. The SVG format scales to any size without loss of quality.

This generator does not currently support adding logos directly. However, if you download the SVG, you can edit it in any vector graphics editor (like Inkscape, Illustrator, or Figma) to overlay a logo. Be sure to use High (H) error correction level to maintain scannability.

WiFi QR codes follow the de-facto standard format (WIFI:T:...;S:...;P:...;;) that is supported by the built-in camera apps on most modern Android phones and iPhones running iOS 11 or later. Some older devices may require a third-party QR scanner app.

The number of modules (small squares) in a QR code depends on the amount of data you encode and the error correction level. More data or higher error correction means more modules and a denser code. If your code looks too dense, try using a shorter URL (via a URL shortener) or lowering the error correction level.
