QR code generator
Make a QR code for a link, Wi-Fi, UPI payment, WhatsApp, contact, location or event. Add your colours, logo and a “Scan me” frame, then download a print-ready PNG or SVG. Free, no sign-up, no watermark.
Preview only: press “Create dynamic QR” or any download button to get your editable code.
SVG keeps your colours and margin but not the dot style, logo or frame. Use PNG for those.
What is inside the QR code
Before you print 100 copies, scan a test print with two or three different phones.
Design
Colours
Dot style
Corner style
Logo
A square PNG works best. With a logo we switch to the strongest error correction (H), so the code still scans.
Frame
Size and margin
Keep at least 2 so phones can find the code. 4 is the standard.
How to make a QR code
- Choose what the QR should open: a link, Wi-Fi, UPI payment, contact and more.
- Fill in the details. The preview updates as you type.
- Pick colours, dot style, a logo and a frame like “SCAN ME”.
- Download PNG or SVG, or print. Test it with two phones first.
Static or dynamic?
A static QR stores your content directly. It works forever, but you can never change it after printing. A dynamic QR stores a short hi4.in link that you can point somewhere new later, so a printed menu, poster or visiting card never goes out of date.
Print tips
- Dark dots on a light background. Inverted or pale codes fail on many phones.
- At least 2 cm wide on a visiting card, 5 cm on a counter, bigger on posters read from far.
- Keep the empty border (quiet zone) around the code. Do not print it to the edge.
- Logo in the middle is fine: it uses error correction H. Keep the logo small and simple.
Questions
Do these QR codes expire?
Static QR codes never expire: the content is inside the code itself and works without hi4.in. Dynamic QR codes point to a hi4.in short link, which has no expiry date unless you set one.
Is there a watermark or scan limit?
No. Downloads have no watermark and no scan limit. The optional “QR made free at hi4.in” line appears only on printed table cards.
Can I add my logo?
Yes. Upload a PNG or JPG. We place it in the centre and switch to the strongest error correction (H) so the code still scans. Use “Test scan” where your browser supports it, and always test a print.
PNG or SVG — which should I download?
PNG keeps every design option (dot style, corners, logo, frame) and suits WhatsApp, Instagram and most printing. SVG is a vector file for designers and large banners, but it is the plain square style with your colours.
Is my data safe?
Static QR codes are made entirely in your browser. Nothing you type, including Wi-Fi passwords, is sent to hi4.in. Only dynamic codes send the link to our server to create the short link.
