Do QR codes ever expire?
Static codes like these never do, as the data is in the pattern. Paid dynamic codes stop once their redirect service ends.

How to make a QR code
Create a QR code for a link, a network or a contact in three steps.
Create your QR code
Pick Link, Wi-Fi, Contact or another type and fill in the boxes. The QR code beside them redraws as you type.
Add a logo and colors
Choose the code and background colors and a square or dot style, then add a logo. Low contrast gets a warning.
Download PNG or SVG
Save a PNG up to 4096 pixels wide, an SVG that stays sharp at any print size, or copy the image into a document.
Free QR codes with no expiration
Every code made here is a static QR code: the link, Wi-Fi login or contact sits in the pattern itself. No server stands between the scan and the page, so there is nothing to switch off, and the code works for as long as the print stays readable.
Many generators make dynamic codes instead. These point to a short link on the company's server, which forwards to your page. You can change the target later and count scans, but when the trial or paid plan ends, the redirect stops and every printed code goes dead.
If a printed code may need a new destination later, point it at a page you control, such as your own website, and change that page instead. The code stays the same, it never depends on us, and nobody tracks who scans it.
Make a QR code for Wi-Fi
Pick Wi-Fi, type the network name and password exactly as your router shows them, and choose the security type, which is WPA on most routers. Guests point their phone camera at the code and tap Join, with no password to read out or mistype.
The code uses the standard Wi-Fi format that iPhone and Android cameras read, and characters such as semicolons in a password are escaped for you. For a network that hides its name, turn on Hidden network and test a scan, as some phones skip hidden networks.
Anyone who scans the code can join, so treat a printed card like the password itself. A guest network keeps visitors away from your own computers and printers, and if you change the password, make a new code to match.
What this QR code maker does
Link to QR code
Turn a website, menu, form or video link into a code. A link typed without https:// gets it added.
Contact QR code (vCard)
Name, phone, email, company and website in one vCard. Scanning it offers to save you as a contact.
QR code with logo
Add a PNG, JPG or SVG logo to the middle. Error correction goes up to 30% so the code still scans.
Custom colors and dots
Any code and background color, square, rounded or dot style, and a check that cameras can read it.
PNG and SVG files
A high resolution PNG up to 4096 px for screens, or an SVG vector file that stays crisp in print.
Text, phone, email, SMS
Plain text, a number to call, an email with its subject and body, or a text message ready to send.
A safe QR code generator
Links, passwords and contacts become a code in this tab and go nowhere else.
Processing
The code is drawn by this page in your browser. Wi-Fi passwords and contact details are never sent.
Storage
Nothing you type is kept. Close the tab and it is gone, and the code holds no short link of ours.
Account
No sign-up, no watermark and no scan limit. Make as many codes as you like, for home or work use.
QR code questions
How do I make a QR code for a link?
Pick Link, paste the address of the website or page, then download the code. Scan it once to check it opens the right page.
How do I make a QR code for free?
Use this page: every type, color, logo and download is free, with no sign-up, trial or watermark, and the codes never expire.
How do I make a QR code for a Google Form?
In the form, press Send, open the link tab and copy the link. Choose Link here, paste it and download the code for your flyer.
How do I make a QR code for a PDF?
Upload the PDF to Google Drive or Dropbox, share it with anyone who has the link, then copy that link into a Link code here.
What size should a QR code be?
At least 2 cm (0.8 in) wide in print, and about a tenth of the scanning distance: a poster read from 3 m needs 30 cm.
How do QR codes work?
Data is stored as dark and light squares. The three large corner squares let a camera find the code and straighten it first.
Can a QR code have a logo in the middle?
Yes. Error correction rebuilds the squares a logo covers. Keep it near a fifth of the width, as this tool does, and test a scan.
