QR Code Generator

What is QR Code Generator?

QR Code Generator creates scannable QR codes for URLs, plain text, WiFi network credentials and pre-filled emails — right in your browser. Pick a mode, type the content, and the code updates live as you type. Colors, error correction level and quiet-zone margin are all adjustable, and the result downloads as a resolution-independent SVG or a PNG at any size from 128 to 1024 pixels.

Features

• Four payload modes — URL, free text, WiFi (SSID + password with proper escaping of special characters) and email (mailto: with subject and body)
• Error correction control — L, M, Q or H, so you can trade capacity against damage tolerance (H survives up to 30% damage, handy under a logo)
• Custom colors — Foreground and background pickers with a built-in contrast guard that warns when scanners may fail to read the code
• Deterministic SVG output — The same input always produces the same file, byte for byte, so it's safe to commit or diff
• PNG export — Client-side render at your chosen pixel size; nothing is uploaded anywhere

How to use

Choose a mode and fill in the fields — for WiFi that's the network name, encryption type and password (hidden entirely for open networks). The preview updates live. Adjust error correction, margin and colors to taste, watch for the low-contrast warning, then download SVG or PNG or copy the SVG markup straight to your clipboard.

Privacy

Codes are generated locally in your browser — WiFi passwords and email contents never leave your device. (A public API endpoint also exists for programmatic use; anything you send there is, by definition, transmitted.)
