What is a QR code and how can you use it in your business?
A QR code stores a link, a text, a WhatsApp chat or your WiFi network, and any phone camera reads it instantly, with no apps to install.
Use it on the table for the menu, in the window for your WhatsApp or on the wall for the WiFi. The ones on this page are static: they don't expire and you won't be charged later.
A well-made QR code serves your customers all day long.
Short links, easier codes
The more information you store, the smaller the squares get. Use short links and leave a clear margin around the code.
Test it before printing
Scan it with two or three phones, from the real distance and in the actual lighting, and check that it opens what you expect.
Tiendana Enseña tip
Give every QR code a reason to be scanned
Hardly anyone scans a code on its own, with no text. Pair it with a line that says what the customer gets: “See the menu and order from your table,” “Message us and we'll deliver it” or “Connect to free WiFi.” The promise is what turns a square of dots into an action.
If you use several QR codes, point each one to a different link, for example by adding ?source=table or ?source=flyer at the end. That way you know which one brings you more customers and can decide where it's worth printing more and where it isn't.
Did you know?
A single QR code can store up to 2.953 bytes, almost three thousand unaccented letters, in a grid of 177 × 177 modules. Even so, the ones that work best out in the real world are the simplest: a short link scans instantly, even from a meter away.

Frequently asked questions
Do the QR codes I create here expire?
No. They're static QR codes: the content is written inside the code and works forever, with no subscriptions or middlemen. They only stop working if the page they point to no longer exists.
Can I change a QR code's link after printing it?
No, because the link is inside the code. If you think the address might change, point the QR code to a page you control, like your online menu or your store, and update that page instead of the code.
What error correction level should I choose?
M (15 %) works for most uses. Use Q or H if the code will be outdoors, on tables that get dirty or on surfaces that scratch, and H whenever you add a logo. Save L for very long content.
Does putting a logo in the center make the QR code fail?
Not if it's done right: the logo covers part of the code and H correction (30 %) rebuilds what's missing. That's why this tool uses H when you upload a logo and limits it to about a quarter of the width. Always test it with your phone before printing.
What size should I print a QR code?
Each side of the QR code should be at least one tenth of the scanning distance: 2 cm to scan up close, about 3 cm on a table and 10 cm or more on a window or poster read from a meter away.
How do I make a QR code so people can connect to my WiFi without me reading out the password?
Choose WiFi network and enter the network name exactly as it appears on the phone, the password and the security type. When scanned, the iPhone or Android offers to connect right away, without typing anything.
How does the WhatsApp QR code work?
It opens a wa.me link with your number and, if you like, a pre-written message. The customer scans it, the chat with you opens and they just tap Send, without saving your number.
Is it better to download the QR code as PNG or SVG?
SVG for print shops and large pieces, because it's vector and scales up without losing sharpness. PNG for social media, WhatsApp or documents; choose 1024 px or more if you're going to print it.
Can I make the QR code in color?
Yes, as long as the code is darker than the background and there's good contrast. A light QR code on a dark background, or one in pastel colors, may not scan on many phones; the tool warns you if the contrast is low.
What happens to the information I put in the code?
It stays on your device: the QR code is generated in your browser, with no sign-up, and we don't store links, WiFi passwords or logos.
