QR Code Generator
Make a QR code for a link, Wi‑Fi network, contact card or message. Pick your colours, add a logo and download it in seconds.
You can leave out https://, it is added for you.
Guests scan the code and join your Wi‑Fi without typing the password.
Scanning saves you straight to the phone’s contacts.
Include the country code, for example +44 or +90, so it works from any country.
Type a link to create your QR code.
Design
Higher levels still scan when part of the code is dirty or covered, but make it denser.
PNG with a transparent background looks best. It never leaves your device.
How to make a QR code
- Choose what the code should do: open a Link, show Text, join Wi‑Fi, save a Contact, write an Email or call a Phone.
- Fill in the fields. The QR code updates as you type, so you always see the result.
- If you like, change the style and colours or add your logo under Design. Dark code on a light background scans best.
- Press PNG for phones, documents and websites, or SVG for printing at any size. Scan it once with your phone camera before you share it.
QR codes, explained simply
A QR code is a square barcode that phones can read with the camera. Point the camera at it and the phone offers to open a website, join a Wi‑Fi network, save a contact or start a message. This generator makes those codes for free, in your browser, with no account and no watermark.
Which type should I choose?
Link is the most common: menus, posters, business cards, packaging and product manuals. Wi‑Fi is perfect for homes, cafés and offices, because guests join without typing a long password. Contact creates a digital business card (vCard) that saves your name, number and email in one tap. Email and Phone open a ready‑to‑send email, call or text message, and Text simply shows any words you type.
These QR codes never expire
Many sites sell “dynamic” QR codes that send people through their own servers first. If the subscription ends, the code stops working. The codes made here are static: the information is stored inside the pattern itself, so they work forever, there is no tracking, and you can use them for personal and commercial projects. The only catch: if your link changes later, you need to make a new code.
Error correction and logos
QR codes contain spare data so they can still be read when part of the pattern is scratched, dirty or covered. Medium is right for most uses. Choose Highest for printed codes that may get worn, and when you add a logo, which covers the centre of the code; the generator switches to Highest automatically. Higher levels make the pattern denser, so for very long content you may need a lower level.
Tips for codes that always scan
- Keep strong contrast: a dark code on a light background. Light‑on‑dark codes fail on many phones.
- Leave the white border around the code. It is part of the code and helps cameras find it.
- Print it at least 2 × 2 cm (about 1 inch), and larger for long links or for posters seen from a distance.
- Shorter content makes a simpler code that scans faster. Use the shortest link you can.
- Always test with a phone or two before printing many copies.
PNG or SVG?
PNG is an image that works everywhere: messages, documents, presentations and websites. Pick 2048 px if you print it. SVG is a vector file that stays perfectly sharp at any size, which printers and designers prefer for flyers, banners and signs.
Private by design
Your QR code is created by your own browser. The link, Wi‑Fi password or contact details you type are never sent to a server and are not saved. Only your design choices, such as colours and style, are remembered on your device.
Frequently asked questions
Do these QR codes expire?
No. The codes are static: everything is stored in the pattern itself and nothing goes through our servers. They keep working forever, even if uTooler disappeared.
Can I use the QR codes for my business?
Yes. The codes are free for personal and commercial use, with no watermark and no limit. Use them on menus, flyers, packaging, business cards and websites.
How do I share my Wi‑Fi with a QR code?
Open the Wi‑Fi tab, type the network name and password exactly as they are, and choose the security type (usually WPA). Guests point the phone camera at the code and tap to join. Remember to make a new code if you change the password.
Why doesn’t my QR code scan?
The usual causes are low contrast, light code on a dark background, a missing white border, or a code printed too small. Use a dark colour on white, keep the border, print it larger, or remove the logo and try again.
Is my data uploaded anywhere?
No. The QR code is generated entirely in your browser and the information you type never leaves your device.
