QR Code Generator Guide: Make QR Codes for Links, Wi-Fi & Contact Cards
A QR code is a shortcut printed in a square. Instead of typing a long web address, spelling out a Wi-Fi password, or keying in a phone number digit by digit, your customer points a phone camera at the square and the phone does the rest. For a small business, that one square can sit on a business card, a menu, a shop window or an invoice — quietly turning foot traffic into website visits, Wi-Fi guests and saved contacts.
This guide shows how to make each kind of code with our free QR Code Generator, and where businesses get the most value from them.
The three codes every small business needs
1. Link (URL) code. The classic. It opens a web page when scanned — your menu, your booking page, your shop, a review page, or a PDF. Because the address lives behind the code, you can change the page later (a new menu, a new offer) without reprinting the code, as long as the address itself stays the same.
2. Wi-Fi code. This code carries your network name and password. A guest scans it and the phone offers to join — no asking at the counter, no password on a sticky note, no typos. It is the single easiest upgrade for cafés, salons, clinics, rentals and waiting rooms.
3. Contact card (vCard) code. This one stores your name, phone, email, business and job title. Scanned, it offers to save you as a contact. Put it on a business card, a trade-show banner, a delivery van or an email signature, and nobody has to type your details — or lose your card.
How to make your code (takes under a minute)
- Open the QR Code Generator and pick a type: Link, Wi-Fi, Contact Card or Text.
- Type your details. The code in the preview updates as you type, so you can watch it change.
- Download the PNG for screens, documents and small prints — or the SVG if the code will be printed large, since SVG stays sharp at any size.
- Test before you print. Scan the downloaded code with your own phone and confirm it opens the right page, joins the right network, or saves the right contact.
Where to put your codes
- Business cards — a vCard code on the back turns a card into a saved contact.
- Restaurant and café tables — menu codes on tent cards; update the menu online, never reprint.
- The counter — a Wi-Fi code by the till ends the password question for good.
- Posters and windows — link to bookings, offers or your reviews page.
- Packaging, invoices and receipts — link to setup guides, support, or a friendly review request.
Print tips that save a reprint
- Size: at least 2 cm × 2 cm for close-up scanning (cards, menus); bigger for posters — a rough rule is one tenth of the scanning distance.
- Contrast: dark squares on a light background. Never invert the code.
- Quiet zone: leave the white border around the code empty — scanners need it.
- One code, one job: do not crowd a small print with three codes; pick the action that matters most.
PNG or SVG?
PNG is a picture file that works everywhere — websites, Word documents, email, small prints. SVG is a vector: the code is stored as shapes, not pixels, so a designer can scale it to a banner or a bus stop without any blur. If a print shop is involved, send the SVG.
