Make a QR code
Paste your online invitation’s link. The shorter the link, the sparser and easier to scan the code.
The code is made in your browser; nothing you type is sent anywhere.
Small tips
Make the code scan first time
Print it big enough, with a light margin
On a paper invitation the code should be at least about 2.5 cm wide, always with a light margin around it. The more modules it has, the bigger it should be printed.
Dark on light
Scanners read a dark code on a light background best. Do not invert the colours (light code on dark) and avoid placing the code over a photo.
Scan a test print
Use the cameras of two or three different phones on a test print. A short link gives a sparser code that scans from further away.
Does this QR code expire?
No. The code holds what you typed directly, with no redirect in between, so it always scans to the same content — as long as your invitation link keeps working.
Why is the bank transfer code only an illustration?
The VietQR codes that banking apps fill in automatically need a bank-issued format. The code here only holds the details as text for guests to read and copy. On a wedding invitation, use the payment QR code from your own banking app.
Should I download PNG or SVG?
PNG suits Zalo, social media or an online invitation. SVG is a vector image that never blurs however large you make it, which is what a print shop wants.
My code looks very dense. Is that a problem?
The longer the content, the more modules the code has. It still scans, but print it larger. If you can, use a short link or fewer accented letters for a sparser code.
