Static vs Dynamic QR Codes
What the redirect actually buys you, measured on real encoded codes, and which payloads are worse off for it.

Discord invites expire by default, and that single setting has killed more printed Discord codes than anything else. Set the invite to never expire with unlimited uses before you generate, and the code will still work at the next event.

Discord already has a code. Here is what it cannot do.
Discord has a QR code inside the mobile app for logging in to the desktop client, which is a different thing entirely: it authenticates a session rather than sharing a server. You will find it under Discord mobile app, login QR scanner. For meeting somebody in person it is the faster option, and this page is not trying to replace it. It runs out in four places.
- The in-app code is a login mechanism. Never print it or share a photo of it, because scanning one can hand somebody access to your account.
- There is no built-in code for sharing a server. An invite link is what you share, and turning that into a scannable code is this page's job.
- So for Discord the usual advice is inverted: the app's own QR code is the one thing you must not put on a poster.
Which Discord link to encode, measured
Characters become modules, and modules decide how small the code can be printed and still read. These are the same link, in the forms Discord actually hands out, each one encoded and decoded when this page was built.
| Link form | Characters | Version | Modules | Print at least |
|---|---|---|---|---|
| Server invitehttps://discord.gg/exampleserverThe short invite domain. Sparse code, and the form to print, once it is set to never expire. | 32 | 3 | 37 | 14.8 mm |
| Invite on the main domainhttps://discord.com/invite/exampleserverThe same invite, eleven characters longer, for no benefit. | 40 | 3 | 37 | 14.8 mm |
| A random invite codehttps://discord.gg/aB3dEf9What Discord generates when you do not set a vanity URL. Short, and impossible to read aloud. | 26 | 2 | 33 | 13.2 mm |
| A user profilehttps://discord.com/users/123456789012345678Eighteen digits of user id, and the densest form here. | 44 | 3 | 37 | 14.8 mm |
discord.gg is one of the shortest link forms on this site, so a server invite code is sparse and prints small. A vanity invite makes it readable as well, which matters when somebody wants to type it instead.
The discord.com/invite form is the same invite with eleven extra characters. There is no reason to print it.
Where a Discord code actually goes
- Gaming events and LAN parties
- A poster or a table card getting people into the server as they arrive. Set the invite to never expire, or the code stops working before the event does.
- Course and community handouts
- Printed once, used for months. This is exactly the case where a 24 hour invite quietly fails and nobody tells the organiser.
- Streamer merchandise and cards
- Long-lived print, so a vanity invite is worth having: it survives, and it can be typed if the camera will not focus.
Three ways these go wrong
- Printing a default invite
- Discord invites expire after 24 hours unless you change it, and can be capped by number of uses. This is the single most common way a printed Discord code fails. Open the invite settings, set Expire After to Never and Max Uses to No Limit, then generate.
- Sharing the login QR code
- The code inside the Discord app logs a device into your account. A photo of it on a stream or a poster is an account takeover waiting to happen. It is not the code you want to print.
- Encoding the long invite form
- discord.com/invite/x is the same destination as discord.gg/x with eleven wasted characters.
The download here stays locked until a decoder has read the finished code back, so the first of those cannot happen to a file you get from this page. For a code whose destination might need to change after printing, the dynamic generator keeps the printed symbol and moves the target.
Codes for the other platforms
Same engine, different link anatomy on each one. The social media hub covers what applies to all of them: the screenshot problem, the codes that only scan inside their own app, and why one code beats six.

Discord QR code questions
How do I make a QR code for my Discord server?
Create an invite, open its settings and set Expire After to Never with Max Uses to No Limit, then copy the discord.gg link and paste it here. The expiry step is the one that matters: a default invite dies after 24 hours and takes every printed copy with it.
Why did my printed Discord QR code stop working?
Almost certainly the invite expired. Discord invites default to 24 hours, and the code on the poster has no way to know. Generate a permanent invite and reprint, and check the setting before the next run.
Is it safe to share the QR code from the Discord app?
No. That code is for logging a device into your account, not for sharing a server. Anybody who scans it can gain access to your account, so never photograph it, stream it or print it. Share an invite link instead.
Can I use a vanity invite in the code?
Yes, and it is worth it for anything printed. A vanity invite is readable, so somebody can type it when a camera will not cooperate, and it does not change if you regenerate the random one.
QRMakery builds this code on your own device. The link you paste and the file you download never reach a server.
