Generate QR codes from text or URLs. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.
A QR Code Generator encodes text — a URL, plain text, contact details, Wi-Fi credentials — into a two-dimensional barcode that a phone camera or scanner can read back instantly. QR codes include built-in error correction, meaning a portion of the code can be obscured or damaged (a logo overlay, a smudge, a fold) and still scan correctly, with the error-correction level you choose trading off resilience against the code's visual density.
Turning a long URL or a block of contact information into something a phone can capture in under a second removes real friction — nobody wants to type out a 40-character link from a printed flyer. Generating the code yourself, entirely in your browser, also avoids routing potentially sensitive data (like a Wi-Fi password or personal contact details) through a third-party QR-generation API that might log what you encode.
Yes — higher levels (Q or H) let more of the code be damaged, obscured, or overlaid with a logo while still scanning successfully, but they also make the pattern denser, which can matter at very small print sizes.
Yes, QR codes have a maximum data capacity that depends on the error correction level and character type used — very long text (thousands of characters) requires a lower error correction level and produces a visually dense, harder-to-scan code.
Yes, using the Wi-Fi format encodes the network name, password, and security type in the standard format that phone cameras recognize and offer to connect to directly.
No, QR code generation happens entirely in your browser using JavaScript, which matters if you're encoding something sensitive like a Wi-Fi password or personal contact information.
SVG is best for printing since it scales to any size without pixelation; PNG is generally simpler for digital use like embedding in a slide deck or web page.
