Generate QR codes from any text or URL. Customizable size and error correction. 100% local.
This tool runs 100% in your browser. All computation happens locally on your device — your input is never uploaded to any server. Results are for reference only.
A QR code is a grid of black and white modules. Structural helpers (the finder squares, timing lines and quiet zone) let any camera locate and size the code; the rest encodes your data plus error-correction redundancy, so scuffed or partially covered codes still decode.
Error correction levels trade capacity for resilience: L=7% recovered, M=15%, Q=25%, H=30% — the higher the level, the less room for data. Higher correction survives a logo overlay or damage better.
The same URL encoded at four levels. Higher correction costs data room but buys damage tolerance — the right choice depends on where the QR will live.
To generate a QR code: enter your URL, text, or WiFi credentials, customize the style and color, and download the QR code — all generated instantly in your browser.

The QR Code Generator is a free, browser-based tool that creates high-quality QR codes for URLs, plain text, vCards (contact info), WiFi credentials, and more.

This tool is for small business owners creating marketing materials, event organizers generating check-in codes, restaurants displaying WiFi QR codes, real estate agents linking to property listings, and anyone who needs a quick, free QR code. If you need to connect physical materials (flyers, business cards, packaging) to digital content, QR codes are the simplest solution.
Select a QR code type (URL, text, vCard, WiFi), enter your data, choose a size (256px to 1024px) and error correction level (L: 7%, M: 15%, Q: 25%, H: 30%). The QR code is generated instantly in your browser using a pure JavaScript library — no server calls. Download as PNG with one click. Higher error correction allows the code to remain scannable even if partially damaged or covered.
A cafe wants to let customers connect to WiFi without typing a password: • QR type: WiFi • SSID: "CafeGuestNetwork" • Password: "espresso2026" • Encryption: WPA2 • Error correction: H (30%) — survives a coffee stain on the printed sign • Customers scan the QR code with their phone camera and tap "Connect" — no password entry needed.
Yes, 100% free with no signup, no watermark, and no usage limits. Generate as many QR codes as you need. All processing happens in your browser — no server calls, no data collection.
You can generate QR codes for: URLs (website links), plain text, vCards (contact information that saves to the phone's address book), WiFi credentials (auto-connect when scanned), email addresses, phone numbers, and SMS messages.
Error correction allows a QR code to remain scannable even if partially damaged. Level L (7% recovery) is fine for digital display. Level M (15%) is standard for printed materials. Level Q (25%) is good for outdoor use. Level H (30%) is best for environments where the code may get dirty or damaged (e.g., restaurant tables, packaging).
No. QR codes generated by this tool are static — the data is encoded directly in the QR code image. They never expire and do not require any service to remain active. However, if you encode a URL, the QR code will stop working if the destination website goes down.
Yes. QR codes generated by this tool are free to use for any purpose, including commercial use. There are no licensing restrictions, no attribution required, and no royalties.
For digital display, 256px is sufficient. For printed materials, use at least 512px (or 1024px for large signs). The minimum printable size is about 1×1 inch (2.5×2.5 cm) at 300 DPI. Always test your QR code by scanning it with a phone before printing in bulk.
