Only Trusted QR Code Generator & Reader
Make a code for a link, a short text, your Wi-Fi, or a contact card. Or read a code from an image further down. No sign-up, and nothing is uploaded: the work happens on your device.
Free · No uploads · On-deviceA bare address such as example.com/menu is treated as https. Check the address before printing: a static code cannot be changed later.
Long text makes a denser code that needs a bigger print size to scan well.
Anyone who scans the printed code gets the password. Put Wi-Fi codes only where you would write the password itself.
Options
Higher error correction makes the pattern denser. Pick High only if part of the code may be covered or worn.

How it works
Drawn and read on your device
Making a code uses an open-source library (@paulmillr/qr, MIT licensed, stored on this site) to turn your text into the black and white pattern. Reading a code tries your browser's built-in BarcodeDetector where it exists, and otherwise uses the same stored library to find the pattern in your image. There is no server involved at any step, and the page still works offline once loaded.
Guide
Picking the right code
- Menus and posters: use URL, print at least 2 cm wide, and test the printed sheet with your own phone before printing many.
- Guest Wi-Fi: use Wi-Fi. Phones join the network from the scan, with no typing. Keep the sheet where only guests see it.
- Business cards: use vCard. The scan offers to save the contact, so include the phone or email people should actually use.
- A link that may change: point the code at a page you control, then change that page. The printed code itself is fixed.
Questions
Do QR codes made here expire?
No. Codes made here are static: the code itself holds your link or text, with no redirect through any server and no account behind it. A static code never expires and keeps working for as long as it stays readable in print. The trade-off is that it cannot be edited or tracked after printing, so check the contents before you print it.
Are my files or details uploaded anywhere?
No. Codes are drawn and read in your browser, on your device. The Wi-Fi passwords and contact details you type are turned into a code locally and are never sent anywhere. Reading a code from an image also happens on your device: the image is not uploaded.
Can I change the link after printing?
No. With a static code the destination is fixed inside the pattern. Services that let you change a destination later use dynamic codes, which route through their server, usually need an account, and can stop working if the service or your plan ends. If the destination might change, point the code at a page you control and change that page instead.
Why will my code not scan?
Most failures come from low contrast, a code printed too small, or damage. Keep dark modules on a light background, print at least 2 cm wide for close-up scanning, and pick the High error correction option if a logo or wear might cover part of the code. Colours are fine as long as the contrast stays strong: this page warns you when a colour pair is too close.
Can this page scan a code with my camera?
Not in this version. Reading works from an image file: drop a screenshot or a photo of a code and the contents show here. Blurry or heavily tilted photos can fail, so a straight, well-lit photo or a screenshot works best.
