AWG Converter

A converter for AmneziaWG configs: turns .conf files into vpn:// keys and back. Runs entirely in the browser — keys and sensitive data never leave your device.

Why

AmneziaVPN lets you share a server three ways: QR code, .conf file, and vpn:// link. The link is the most convenient option for messaging apps, but there's no built-in way to generate one from an existing .conf file. This tool fills the gap:

• You have a WireGuard/AmneziaWG .conf file → get a shareable vpn:// link
• Someone sent you a vpn:// but you need a .conf (e.g. for a router or another client) → decode it back

Features

• 🔒 Fully local — no backend, keys never leave the browser
• 🔄 Both directions — .conf → vpn:// and vpn:// → .conf
• 🛡️ AmneziaWG 2.0 — full support for obfuscation parameters (H1-H4, S1-S4, Jc/Jmin/Jmax, I1-I5)
• 📋 Amnezia-compatible — generated links work with the official AmneziaVPN app
• ⚡ Zero dependencies — uses native browser APIs for compression and base64

How to use

1. Open the app
2. Pick a direction — .conf → vpn:// or vpn:// → .conf
3. Paste your config into the textarea
4. Hit "Convert"
5. Copy the result

How it works (technical)

The Amnezia vpn:// format is:

vpn:// + URL-safe base64( qCompress( JSON ) )

where qCompress is Qt's compression format: 4 bytes (big-endian) of uncompressed data size, followed by zlib-compressed data. The inner JSON has a specific two-level structure — an outer containers[0].awg object and an inner last_config (a JSON string), which the app parses to register the server.

The converter implements both directions: parses .conf, builds the correct JSON structure, compresses via the CompressionStream API (with manual adler32 correction, since browsers compute it incorrectly), and encodes to URL-safe base64.
