Community managers, crypto projects, and local businesses print Telegram channel QR codes on flyers, stickers, and conference badges so people join with one scan instead of searching usernames. Hosted QR SaaS charges ~$49/month for a static link — you can generate the same PNG locally for free.
Get your Telegram invite link
In Telegram:
- Open your channel or group
- Tap the channel/group name → Invite Links (or Add Members → Invite to Group via Link)
- Copy the
https://t.me/...invite URL
Examples:
https://t.me/yourchannel
https://t.me/+AbCdEfGhIjKlMnOp
Encode the full HTTPS URL as the QR payload. Scanners open Telegram (app or web) on the join screen.
Tip: create a dedicated invite link per campaign so you can revoke one flyer without rotating your main link.
