Free Signal QR Code Generator — Contacts & Groups

To message you, yes. To scan, no. The code encodes an ordinary HTTPS URL, so any phone camera reads it and opens signal.me in the browser. If Signal is installed the link hands off to the app and opens the chat. If it is not, the page explains what Signal is and links to the app store — which is a reasonable outcome, but it means your audience needs a reason to install before the code converts.

A signal.me link does not display your number to someone who scans it. That is the main reason to use one. Be aware that Signal itself is registered to a phone number and your contacts may see it depending on your privacy settings and whether they already have you saved — so the link protects you from strangers, not from Signal's own account model. Check your Signal privacy settings separately if that distinction matters to you.

A contact link (signal.me/#p/...) opens a private one-to-one conversation with you and nobody else sees it. A group invite link adds the scanner into a group where existing members are visible to them and they are visible to existing members. For a tip line or a public point of contact, always use the contact link. Group invites are for communities that intend to be mutually visible.

Group links yes, contact links effectively no. Signal lets you reset a group invite link, which invalidates every printed copy at once — a genuinely useful safety valve. A signal.me contact link is tied to your account and stays valid as long as the account does, so treat printing one as a permanent publication decision rather than a reversible one.

Static, in most privacy-sensitive cases. A dynamic code routes each scan through a vendor redirect that records it, which introduces a third party into a chain you chose Signal specifically to keep short. A static code encodes the signal.me URL directly, involves nobody, costs nothing and never expires. The trade-off is that you cannot repoint it, which for a permanent contact link is rarely the constraint.

Not reliably. A signal.me link is bound to the registered account, so re-registering on a new number can invalidate it. If you know a number change is coming, either wait to print or use a dynamic code you can repoint — accepting the tracking trade-off described above. A silently broken tip line is the worst of the available outcomes.

Structurally no — all three encode an HTTPS deep link — but the reason people choose them differs. Signal is picked for end-to-end encryption by default and minimal metadata retention. If your requirement is reach rather than privacy, WhatsApp has vastly more installed users and Telegram sits in between. Choose the platform your audience already has, unless the encryption is the point. For a general contact route rather than a messaging one, a vCard code carries your details with no app at all.

Yes. Static Signal codes are free with no signup, no watermark and no expiry, which is also the configuration we would recommend for this use case regardless of price. SVG and PDF export start at $5/month if you need vector output for print.
