QR Code Generator

Generate QR codes for URLs, WiFi credentials, email, phone, SMS, and vCards. Render as inline SVG (resolution-independent) or download as PNG. Configurable error correction (L / M / Q / H) so you can balance density against scan robustness. Everything runs locally — your QR payload never reaches a server.

QR codes pack a lot

A QR code is a 2D barcode that holds up to ~3 KB of data and can be scanned by any modern phone in under a second. The format is open (ISO/IEC 18004), free of patents, and renders as crisp pixel art in any size — perfect for posters, business cards, packaging, and on-screen displays.

This generator handles the common payload presets so you do not have to remember the exact text formats:

• URL — https://example.com/path
• WiFi — auto-join Wi-Fi networks
• Email — mailto: with optional subject and body
• Phone — tap to call
• SMS — pre-filled message
• vCard — contact card import
• Geo — open in maps
• Plain text — anything else

Output formats

• SVG — vector, scales to any size without quality loss. Best for print and high-DPI displays. Edit in any vector editor.
• PNG — raster, fixed pixel size. Drop straight into design tools, slack messages, screenshots.

For most use, SVG is the better default — it stays sharp at every size.

Common workflows

Print a Wi-Fi QR for guest network. Generate at error correction H, print at 4×4 cm or larger. Phones scan from across the room.

Add a quick-call QR to packaging. Phone preset → high error correction → 3×3 cm minimum. Customers scan and call without typing.

Embed a vCard at a conference. Print the QR on your name badge. Connections walk away with your contact in their phone — no LinkedIn dance.

Build a feedback link. URL preset pointing at your form. Add UTM params before generating to track scan source.

Why local generation matters

A QR code can carry your phone, email, address, Wi-Fi password — anything from a “scan me” badge. Generating through a remote service routes that data through their server. The tradeoff is rarely worth it. This generator runs entirely in your browser using the open QR encoding library — every byte stays on your machine.
