QR code wedding card: make it and keep the PDF WhatsApp-ready
Send the wedding invite PDF on WhatsApp as a document, which allows up to 2GB, and print one QR code on the card for the venue map, an RSVP form or a chat. Compress a lighter copy for phones, test the code on two phones, and keep any UPI QR separate from the invite.
Send the wedding invite as a PDF using WhatsApp's document option, and print a QR code on the card that opens one thing: the venue map, an RSVP form or a chat with the host. WhatsApp takes documents up to 2GB and a personal Gmail account takes 25MB per message, so the limit is rarely the problem. Slow opening on a relative's phone is.
Make the code with the QR code generator: it handles links, text, contact cards and WhatsApp, with custom colours, a centre logo and PNG or SVG download. Shrink a heavy invite with Compress PDF.

Why the invite should go as a document
When you send a card as a photo, WhatsApp compresses it, and the fine gold lettering turns soft. WhatsApp compresses media unless you send it as a document or switch on HD. A PDF sent through the attach menu as a document arrives exactly as your designer made it. Our guides on WhatsApp file size limits and sending HD photos cover the menus on both phones.
The common mistake is forwarding a screenshot of the card. It looks fine on your screen and blurry on everyone else's, and the QR code inside it may no longer scan.
What to put behind the QR code
| Purpose | QR type | Tip |
|---|---|---|
| Venue directions | Link | Paste the map link for the hall's entrance, not the city |
| RSVP or meal choice | Link | Use a form and test it from another account |
| Message the host | Opens a chat with a ready message | |
| Full e-invite | Link | Drive link set so anyone with it can view |
| Venue Wi-Fi | Wi-Fi | Only for guests staying at the venue |
Pick one purpose per code. A card with three small codes confuses elderly guests, and two of them will go unused.
Make and place the QR in four steps
- Pick one destination. Open the map link or form in your browser first and confirm it loads without a sign-in.
- Generate the code. Paste the link into the QR tool and choose dark colours on a light background.
- Download the file. Take the SVG for printing and give it to your designer, and keep the PNG for WhatsApp.
- Test before printing. Scan it with two different phones from arm's length, and again after it is placed on the card.
If you add a logo in the centre, keep it small and scan again. A bigger logo hides part of the pattern, and some cameras then fail to read it. A screenshot of the finished card can be checked with scanning a QR from an image.
For relatives who do not use WhatsApp
Some elders still read mail more than chat. Personal Gmail takes attachments up to 25MB per message, and anything larger turns into a Drive link. Work or school accounts have a limit set by the administrator. A compressed invite PDF fits comfortably, so email it with the venue and the date written in the message itself. That way the key details are readable even before the attachment opens.
Write the date, time and hall name as plain text beside the QR code on the card as well. The code is a shortcut for people with phones, and the words are the backup for everyone else.
For the WhatsApp contact code
A WhatsApp QR works through a wa.me link, which needs the number in full international format with no zeroes, brackets or dashes. For an Indian number that means 91 followed by the ten digits. The WhatsApp QR generator builds that link and can pre-fill a message such as "Attending the wedding". Our note on WhatsApp QR codes explains the link in detail.
Keep the PDF light for guests on slow data
Assume your designer hands you a 40MB PDF because every page carries print-quality images. WhatsApp will send it, but a guest on a weak connection will wait for it to download. Send a lighter copy for phones and keep the heavy one for the press. Open Compress PDF, pick the copy, and then check the new size. Here is how to check a PDF's size on a phone.
Open the compressed file and look at the pages yourself, especially the names and the venue address. If a line of small text has gone fuzzy, compress less.
A simple sending plan
Wedding dates depend on the muhurat your family chooses, so build the plan backwards from your own date. This is a suggestion, not a rule.
- A few weeks before: send the invite PDF as a document, with the RSVP code on it.
- About a week before: send a short reminder with the venue map link or code.
- The day before: share the venue pin on WhatsApp for guests travelling in.
Do not mix a payment QR into the invite
Some families add a UPI QR for gifts. If you do, keep it away from the invitation itself. RBI's BE(A)WARE guidance says never to scan a QR code to receive money, and receiving money never needs a PIN. A guest scanning a code to pay you enters their own PIN, so label it clearly. Read how QR scams on UPI work before you print one.
Common mistakes
- Sending the card as a photo, so WhatsApp compresses it.
- Using a map link for the city, so guests land in the wrong lane.
- Pointing the code at a private Drive file or a form that asks guests to sign in.
- Printing the QR too small or in a pale colour.
- Skipping the test scan after the designer has placed it.
Print a second code-free line under the QR with the short web address in words, for guests whose camera will not scan.

Frequently asked questions
Can I send a wedding card PDF on WhatsApp?
Yes. WhatsApp allows documents up to 2GB. Use the attach menu and choose Document so the file is not compressed like a photo. The PDF reaches guests exactly as it was designed.
How do I add a QR code to a wedding card?
Generate the code from a link, save it as SVG or PNG and give it to your designer to place on the card. Test the printed proof by scanning it with two phones before the full print run.
How do I make a wedding card PDF smaller for WhatsApp?
Use a PDF compressor on a copy of the file, then check the new size and open every page to see the text is still sharp. Keep the original for the printer. Personal Gmail allows 25MB per message, so a lighter copy works there too.
Which QR code type should I use for the venue location?
Use a link code that opens the venue's map location. Open the link on your phone first to confirm it lands at the entrance of the hall and not on a general area.
Is it safe to put a UPI QR code on the invitation?
It is better not to. RBI's BE(A)WARE guidance says never scan a QR code to receive money, and receiving money never needs a PIN. If you share one, label it as a way to send a gift.
Why does my invite look blurry on WhatsApp?
It was probably sent as a photo, and WhatsApp compresses media. Send the PDF or the image as a document, or turn on HD when attaching a photo.
