Gender Reveal QR Code

Boy or girl? The answer is encoded inside the code — not on a website, not in a post, not in a bakery order that three people already know. Everyone scans on the count of three and the answer appears on every screen at once. The frame is violet on purpose: the one party color that refuses to pick a team. Your browser proves the code scans before you print a single card, and if the person who types the message isn't you, even you get to be surprised.

How it opens
Keepsake template

Every swatch above is a real code rendered by this site's engine at build time — scan one.

A frame leaves the code untouched, so it can carry a lighter error-correction level — usually one or two sizes smaller, which matters on a gift tag. It still has to pass the same decode check before you can download it. Not available with heart modules or a photo weave, which spend that margin on the decoration.

Colors only touch the frame art — the code itself stays black on its white panel.

Fill in the form — your keepsake appears and is verified as you type.

Codes render on light backgrounds for reliable scanning.

A worked example, rendered by the real engine
 
 
Boy or girl? Scan on three!
 
 

Built when this page was built, by the same engine as the tool above — confetti frame, the
        code panel untouched, and the answer itself inside the modules. Scan it from the screen (no
        internet needed) and it says:

 
It's a GIRL! Team pink wins - see you in March.

Running the reveal without a leak
 
 
     
  1.  Pick the one person who knows. They type the answer, watch the verified
        badge appear, download the file, and close the tab. Nothing was uploaded, so the secret now
        lives only in the file and on whatever they print.

    2.  
  2.  Seal the cards. One per guest or per couple, face-down or in envelopes.
        Cameras read codes any time — paper is the only secrecy that works.

    3.  
  3.  Run a decoy round. Hand out a practice code first — encode "Not yet!
        Snacks first." — so every phone at the party has proven it can scan before the moment that
        counts.

    4.  
  4.  Count down and scan together. Phones up, three-two-one. Team pink or team
        blue lands on every screen at the same second — and the cards go home as keepsakes.

    5.  
 
  
 
     
  •  Guest reveal cards: A6 (10.5 × 14.8 cm) with the code at 3–4 cm scans
        instantly at hand distance — the framed artwork fits A6 naturally, and the caption line
        ("Boy or girl? Scan on three!") prints with it.

    •  
  •  The one big board: a single A4/A3 print beside the cake or balloon arch
        lets latecomers join. Rule of thumb: the code should be at least one tenth of the farthest
        scanning distance.

    •  
  •  Cupcake toppers and favor tags: keep the code itself at 2.5 cm minimum —
        smaller than that, party lighting starts costing scans.

    •  
  •  Always keep the white margin. The quiet zone around the code is part of
        the symbol — trimming it flush to the frame art is the most common self-inflicted scan
        failure.

Gender reveal code FAQ
 
 
 Can we stay surprised ourselves? 
Yes — and this is the trick that beats a cake order. Have the one person who knows (the sonographer, a friend, the envelope-keeper) type the answer into the generator and download the code with their eyes on the screen, not yours. Nothing is uploaded — the message is encoded and verified entirely in that browser — so once the file is saved and the screen is closed, the answer exists only inside the code. You can print your own reveal and genuinely not know until you scan it with everyone else.
 
 Can someone scan the code early and spoil it? 
Anyone who scans it sees the answer — a QR code hides nothing from a camera, only from eyes. Secrecy comes from paper: keep the cards face-down, sealed in envelopes, or hand them out at the moment itself. The violet frame helps too — deliberately neither pink nor blue, it gives away nothing on the table.
 
 Does the reveal need internet at the party? 
Choose the offline note mode and the words are written into the code itself — a backyard, a park, or a barn with no signal all work. Be aware that iPhone and Google Lens have no way to display bare text and may offer a web search instead; it reads properly on Samsung phones and in scanner apps. The reveal-link mode shows a proper reveal page on every phone but needs a signal at the party. Either way, run one test scan at the venue beforehand.
 
 What should the message say? 
Short lands hardest: "It's a GIRL! Team pink wins — see you in March." You have room for much more, but every extra character makes the code denser; under a couple of hundred characters it stays chunky and scans across a party table in one try.
 
 Is the answer uploaded anywhere before the party? 
No. The message is encoded, drawn, and decode-verified entirely in the browser — nothing is transmitted, stored, or posted. Until the first person scans a printed card, the answer exists only on paper. There is no account, no link to guess, and nothing for a curious relative to find.
 
 
 
 

After the party, announce the arrival with a baby reveal code — the news hidden the same way. Or run the whole party as a QR treasure hunt that ends at the reveal, and weave the first ultrasound photo into a photo keepsake code.
