QR code generator

Turn any text or configuration URI into a downloadable QR code, with size and error-correction options.

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.

How it works

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.
