Reddit QR Code
Free Reddit QR Code Generator
Encode a subreddit, post, profile, or comment permalink into a QR — with a warning about the share link Reddit hands you, which is 32% wider than it needs to be.
Quick answer
A Reddit QR code encodes a reddit.com URL so someone can scan it and open a subreddit, post, profile, or comment. Paste the link, style it, and download a PNG, SVG, or PDF, free and with no watermark. One thing worth knowing first: the URL Reddit's Share button gives you carries tracking parameters that make the code noticeably denser. Use the redd.it short link instead and the code comes out 49% narrower.

About Reddit QR Codes
Copy a link from Reddit's Share button and you get something ending in ?utm_source=share&utm_medium=web2x&context=3. Those parameters are for Reddit's analytics, not yours, and they make your QR code measurably worse.
We measured it. A post permalink encodes to a 37x37 grid. The same post with Reddit's share tracking attached needs 49x49, which is 32% wider per side at the same printed size, so every module gets smaller and the code gets harder to scan. Strip the parameters, or better, use the redd.it short form, and the grid drops to 25x25.
That is the single most useful thing to know about Reddit QR codes, and no other generator page mentions it. The rest of this page covers which Reddit URL to encode, and clears up the two other things people mean when they search for this.
Strip the share parameters first
This is the whole trick, and it takes five seconds. We encoded the same Reddit post four ways at error correction M and recorded the module grid.
| What you paste | Characters | Grid at M | Verdict |
|---|---|---|---|
redd.it/1abc2de short link | 23 | 25x25 | Best. Shortest possible, still official |
reddit.com/r/subreddit/ | 39 | 29x29 | Fine for a subreddit |
| Full post permalink | 79 | 37x37 | Workable, but longer than needed |
| Permalink + Reddit share tracking | 123 | 49x49 | Avoid. 32% wider per side for no benefit |
- Deleting everything from the
?onwards is safe. The tracking parameters carry no routing information, and the link resolves identically without them. - The
redd.itshort form is 49% narrower than the tracked URL, which at a fixed printed size means each module is nearly twice the width. - Measured with the same ISO/IEC 18004 encoder our generator uses. Reproduce it with any compliant library.
Which Reddit URL to encode
Reddit URLs are consistent once you know the patterns. Pick the most specific destination that will still be valid later, and prefer the shortest form of it.
| Destination | URL pattern | Best for |
|---|---|---|
| Subreddit | reddit.com/r/name | Community posters, event signage, zine inserts |
| User profile | reddit.com/user/name | Creator business cards, conference badges |
| Specific post | redd.it/postid | Anything printed. The short form keeps the code coarse |
| Comment permalink | reddit.com/r/name/comments/id/slug/commentid | Citing one answer. Long, so give it room |
| Wiki page | reddit.com/r/name/wiki/index | Community rules and FAQs on printed material |
- Use
www.reddit.comrather thanold.reddit.comon anything public. The old interface is a personal preference and can disorient people who have never seen it. - Avoid encoding a link to a post you do not control. Posts get deleted, and a printed code pointing at a removed thread is worse than no code.
- For a community that will outlive any single post, encode the subreddit rather than a thread.
The other two things people mean
"Reddit QR code" pulls in two searches that have nothing to do with generating one, which is worth knowing so you do not waste time on the wrong page.
| What you want | What it is | Where |
|---|---|---|
| A code linking to Reddit | A QR encoding a reddit.com URL | This page |
| The app login QR | A code Reddit shows for signing in on another device | The Reddit app, under login. Not generatable elsewhere |
| 3DS QR codes | Nintendo 3DS homebrew codes shared in r/3dsqrcodes | That subreddit. Unrelated to this entirely |
- Never scan a Reddit login QR that arrives by direct message. Legitimate login codes only appear on a screen you navigated to yourself.
Walkthrough
How to Create a Reddit QR Code
Copy the link, then strip the tracking
Reddit's Share button appends
?utm_source=share&utm_medium=web2x&context=3. Delete everything from the?onward. The link works identically and the code comes out substantially coarser.Prefer the short form for posts
Reddit offers
redd.it/postidfor individual posts. It is official, it resolves to the same thread, and it encodes in 23 characters against 123 for a tracked permalink.Decide static or dynamic
Static is free and permanent, which suits a subreddit link. Choose dynamic if the code is printed and might need to point at a different thread later, such as a pinned announcement that rotates.
Keep the styling simple
Reddit orange on white is recognisable, but contrast matters more than brand colour. If you add a logo, keep it under 25% of the width — see the logo guide.
Test it before printing
Scan the finished code at the size and distance people will use. Long comment permalinks in particular produce dense grids that need more physical room than you would expect.
Where it works
Reddit QR Code Use Cases
Community event posters linking to the subreddit so attendees can join the discussion before they arrive
Creator business cards pointing at a Reddit profile, where a portfolio of answers often says more than a website
Conference and meetup signage linking to a pinned thread carrying the schedule or a live Q and A
Product packaging and inserts pointing at a support subreddit, which costs less to run than a ticket queue
Zines, flyers, and posters in a local community linking to the neighbourhood subreddit
Academic posters citing a specific comment or thread as a source, using the permalink
Game and homebrew documentation linking to the relevant community wiki page
Stickers for a subreddit that anyone can print and place, which is how several communities grew
What works in practice
Reddit QR Code Best Practices
Always strip Reddit's share tracking parameters before encoding. It is the single highest-value change and it is free.
Use redd.it short links for individual posts on anything printed.
Encode the subreddit rather than a thread when the material will outlive any one post.
Do not point a printed code at content you do not control, since posts get deleted and codes do not.
Prefer www.reddit.com over old.reddit.com for anything a stranger will scan.
Give comment permalinks extra physical size, because they are the longest Reddit URLs and produce the densest codes.
Use a dynamic code when the destination is a rotating announcement rather than a stable community.
Reddit QR Code FAQ
Common questions about generating, printing, and deploying these codes.
How do I make a QR code for a subreddit?
Paste https://www.reddit.com/r/yoursubreddit into the generator above and download. Free, no watermark, and a static code never expires. Subreddit URLs are short, so the code stays coarse and easy to scan.
Why does Reddit's share link make a worse QR code?
It appends tracking parameters for Reddit's analytics. We measured a post permalink at 37x37 modules and the same link with share tracking at 49x49, which is 32% wider per side. Delete everything after the ?.
What is a redd.it link?
Reddit's own short-link domain for individual posts, in the form redd.it/postid. It resolves to the same thread and encodes in 23 characters instead of 123, producing a code 49% narrower than a tracked permalink.
Can I make a QR code for a Reddit post?
Yes. Use the redd.it short link where possible, since full permalinks are long and produce dense codes. Bear in mind that a printed code pointing at a deletable post is a risk you cannot fix later.
Where is the Reddit app login QR code?
Inside the Reddit app itself, under the login flow. It is generated for your session and cannot be produced by any external tool. Never scan one that arrives by direct message.
What are 3DS QR codes?
Nintendo 3DS homebrew and game codes shared in the r/3dsqrcodes community. They are unrelated to generating a QR code that links to Reddit, though both searches land on the same results page.
Should a Reddit QR code be static or dynamic?
Static for a subreddit or profile, which do not move and cost nothing. Dynamic if the code is printed and points at a rotating announcement thread, so you can repoint it without reprinting.
Does old.reddit.com work in a QR code?
It encodes fine, but avoid it for anything public. The old interface looks unfamiliar to anyone who joined in the last several years, and a confusing landing experience defeats the point of the scan.
