Type something above to make your QR code.
How to make a QR code
- Choose what the code should hold: a link or text, a Wi-Fi network, or a WhatsApp chat.
- Fill in the box. The QR code appears while you type.
- Pick a size and colours if you like. Dark code on a light background scans best.
- Save it as PNG for screens and documents, or SVG for printing at any size.
About this tool
A QR code is a square picture that a phone camera can read. People use them on posters, menus, business cards, shop windows and invitations so that others do not have to type a long address.
The codes made here are static. The information is stored inside the picture itself, so the code never expires and does not depend on our website. We do not track scans, and nothing you type is sent to a server. This tool makes standard codes with medium error correction, which means a small scratch or smudge will not stop them from scanning.
Wi-Fi codes let guests join your network by scanning, without typing the password. WhatsApp codes open a chat with your number, with an optional first message already written.
Tips and common problems
- Test before you print. Scan the code with two different phones before it goes on a poster or card.
- Keep strong contrast. A dark code on a light background is safest. Light code on a dark background fails on many scanners.
- Do not print it too small. About 2 cm (an inch) wide is the smallest comfortable size for a short link, and bigger for longer text.
- Use a short link. Short text makes a simpler code that scans faster from far away.
- Leave the white border. The empty margin around the code is part of it. Do not crop it.
- Wi-Fi password changed? Make a new code, because the old code still contains the old password.
Common questions
Is the QR code generator free?
Yes. It is free, there is no signup and no watermark, and you can use the codes for personal or business purposes.
Does the QR code expire?
No. These are static codes, so all the information is inside the picture. They keep working as long as the link or information inside is still valid.
Can I make a QR code for my Wi-Fi?
Yes. Choose the Wi-Fi tab, type the network name and password, and guests can join by scanning with their phone camera.
Why will my QR code not scan?
Usually the code is too small, the colours do not have enough contrast, the white border was cropped, or the text is very long. Make it bigger, use a dark code on a light background, and shorten the text.
How much text can I put in it?
About 200 characters. For longer content, put the text on a web page and make a code for that link.
Is my data uploaded anywhere?
No. The QR code is created in your browser and what you type never leaves your device.
QR Code Generator in detail
What you can put in a QR code
A QR code is simply text that a phone camera can read. This tool makes three common kinds: a link or any text, a Wi-Fi code that lets guests join your network without typing the password, and a WhatsApp code that opens a chat with your number, optionally with a ready-made message.
Wi-Fi codes
Enter the network name exactly as it appears, choose the security type (most routers use WPA or WPA2), and type the password. When someone scans the code with a modern phone camera, the phone offers to join the network. Print it and place it in your shop, office or living room. If you change your router password later, make a new code.
WhatsApp codes
Type your number with the country code and no spaces or plus sign problems, then add an optional message. Customers who scan it land in a chat with you. This is useful on business cards, shop doors and posters.
Making a code that scans every time
Keep strong contrast between the code and its background, dark on light works best. Do not make the code too small: for print, about two centimetres is a practical minimum, and larger is safer when people scan from a distance. Leave a clear empty border around it. Always test the final code with two different phones before printing in bulk.
PNG or SVG?
PNG is simple and works in documents, chats and social posts. SVG is a vector file that stays sharp at any size, so choose it for posters, banners and professional printing. The code is generated in your browser and the data you enter is not sent to us, so the codes do not expire and do not depend on our site.
