How to import a WireGuard config on Windows
Got a ready .conf from your server or provider? Here are two ways to connect it on Windows — via the official WireGuard app and via GANVAS (with a config check, kill switch and leak protection).
| Step | WireGuard app | GANVAS VPN |
|---|---|---|
| Add the config | Import Tunnel(s) → .conf file | “Custom config” → paste text or file |
| Config check | No | Yes, before connecting |
| Leak protection | Per config | Kill switch + DNS/WebRTC |
| Other protocols | WireGuard only | VLESS and Tor too |
Way 1. The official WireGuard app
Download the client from wireguard.com, click Import tunnel(s) from file, pick the .conf file and click Activate. If your config came as text, save it to a file with the exact .conf extension (a common cause of import errors).
Way 2. Paste the config into GANVAS (easier)
Download GANVAS VPN, open “Custom config” and paste the text (the [Interface] and [Peer] sections) or pick a file — the app validates it and connects it as its own server. It's the same custom-config client that also runs VLESS and Tor.
Common import errors
The file was saved as .txt instead of .conf; the [Interface] section has no DNS; the [Peer] has no AllowedIPs; a corrupt private key. Every config field is explained in our WireGuard from A to Z guide. Confirm your real IP is hidden afterwards with our VPN check.
FAQ
Can I paste the config as text instead of a file?
Yes. In GANVAS, open “Custom config” and paste the [Interface]/[Peer] text. The official WireGuard app needs a .conf file.
Why won't my config import?
Usually the file was saved as .txt rather than .conf, or the config is missing AllowedIPs/DNS. Check the extension and the required fields.
Is the .conf extension required?
For the official app, yes. In GANVAS you can just paste the config text with no file.
Is it free?
Yes, your own WireGuard configs work in GANVAS for free with no signup.
Which systems are supported?
Windows (desktop), plus Android and Linux.
