What is the QR Code Generator?
The ToolZen QR Code Generator turns a link, a message or a few details into a QR code that any phone camera can scan. You can make a code for a website link, a WhatsApp chat with a ready-made message, a Wi-Fi network so guests can join without typing the password, an email, or a phone number. Pick the colours, the size and the error correction, then download the code as a PNG picture or as a SVG file that stays sharp at any size. The code is made inside your browser, so what you type is never sent to a server.
How to use the QR Code Generator
- Choose what the code is for: Link / Text, WhatsApp, Wi-Fi, Email or Phone.
- Fill in the details. The QR code appears and updates as you type.
- Pick the image size, the colours and the border if you want a different look.
- Scan the code with your phone camera to test it, then press Download PNG or Download SVG.
Benefits and use cases
- Shop owners who want customers to open their WhatsApp chat or Facebook page with one scan.
- Cafes, offices and homes that share a Wi-Fi password without writing it on the wall.
- Posters, flyers, business cards and invoices that need a scannable link.
- Event organisers sharing a form, a map or a menu.
Tips for best results
Always test the code with your phone before you print it. Keep a strong contrast: a dark code on a light background scans best, and a code with light colours on a dark background can fail on some scanners. Leave the empty border around the code, and print it at least 2 cm wide. Short links make simpler codes that scan faster, so shorten a very long address first. If you expect the printed code to get scratched or dirty, choose the High error correction.
ToolZen tools run in your browser, so your details are not uploaded to a server. Bookmark this page and come back whenever you need a new code. There is nothing to install and no account to create.
Frequently asked questions
Do I need to sign up to use the QR Code Generator?
No. There is no sign-up, no watermark and no limit on how many codes you make. The codes never expire, because they contain the information itself and are not stored on our server.
How do I make a WhatsApp QR code?
Open the WhatsApp tab, type the phone number with the country code, for example 94771234567, and add a message if you want one. When someone scans the code, WhatsApp opens a chat with your number.
Can I make a QR code for my Wi-Fi?
Yes. Open the Wi-Fi tab, type the network name and password, and choose the security type. Most modern phones join the network when they scan the code.
What is the difference between PNG and SVG?
PNG is a normal picture, good for sharing and for most printing. SVG is a vector file that can be enlarged to any size without getting blurry, which is useful for big posters and banners.
What does error correction mean?
It adds extra data so the code still scans when part of it is dirty or damaged. Higher levels survive more damage but make the code denser. Medium is a good choice for most uses.
Is my information uploaded?
No. The code is drawn in your browser. Your text, Wi-Fi password and phone number stay on your device.
