Generador de códigos QR

Convierte cualquier texto o URI de configuración en un código QR descargable, con opciones de tamaño y corrección de errores.

Text or configuration URI

Enter text to render a QR code

Size (px)Error correction

Higher error correction makes denser codes that survive partial damage but hold less data. Very long inputs may exceed the QR capacity limit.

Cómo funciona

Enter the text or URI to encode.
Pick a size and an error-correction level.
Download the PNG — the QR is rendered locally and never uploaded.

Paste any mix of proxy URIs and get a per-line breakdown: protocol, address:port, network, security and name.

Config inspector

Inspect a single configuration URI field by field: protocol, transport, TLS, SNI, path and more.

Base64 encode / decode

Encode text to Base64 or decode subscription payloads, with padding- and URL-safe-tolerance.

Config validator

Check a list of URIs for syntax errors and get factual notes about missing SNI or insecure flags.
