Quick answer: To make a QR code, choose what it should contain, enter the details and download it as PNG or SVG. These static codes never expire and are not tracked. The code is generated in your browser, so your link or Wi-Fi password is never uploaded.
How to use the QR Code Generator
- Choose what the code should contain: a link or text, Wi-Fi, email or a phone number.
- Fill in the details. The QR code updates as you type.
- Pick the size and colors if you like, then download the PNG or SVG and test it with your phone.
What you can put in a QR code
- Link or text: a web address, a short message or any plain text.
- Wi-Fi: your network name, password and security type. Phones that scan the code offer to join the network.
- Email: opens a new message with the address, subject and text already filled in.
- Phone number: starts a call after the scan.
Static codes: no tracking, no expiry
These codes store your information directly in the pattern. They do not go through a FormatVolt redirect, so there is no scan tracking, no account and no expiry date or subscription. The trade-off is that a printed code cannot be edited. If the link or password changes later, you need to make a new code. For that reason, use a link you control and expect to keep.
Tips for a code that scans reliably
- Dark on light. Black on white scans best. Light-on-dark or low-contrast colors can fail on some scanners.
- Keep the quiet zone. The empty margin around the code (4 modules by default) helps scanners find it.
- Size. Make printed codes at least about 2 cm (0.8 in) wide, and larger if people scan from a distance.
- Error correction. Level M is a good default. Levels Q and H survive more damage or a logo placed on top, but they make the pattern denser.
- Test it. Scan the finished code with more than one phone before you print or publish.
PNG or SVG?
PNG is a picture file that is ready for websites, documents and social posts. SVG is a vector file that stays sharp at any size, which makes it the better choice for posters, signs and print.
Privacy and safety
Everything is generated in your browser, so your link, text and Wi-Fi password are not sent to FormatVolt. Remember that anyone who scans a Wi-Fi code can read the password inside it. When you scan codes from strangers, check where the link leads before you open it.

Frequently asked questions
Is the QR code generator free?
Yes. There is no sign-up, watermark or limit, and the codes do not expire.
Do these QR codes expire or track scans?
No. The information is stored directly in the code, so there is no expiry and no scan tracking. A printed code also cannot be changed later.
Should I choose PNG or SVG?
Use PNG for websites and documents. Use SVG for print and large formats because it stays sharp at any size.
How do I make a Wi-Fi QR code?
Choose Wi-Fi, enter the network name, the password and the security type, then download the code. Phones that scan it can join the network.
Are my details uploaded?
No. The code is created in your browser and your text, links and passwords are not sent anywhere.
Why does my QR code not scan?
Usually the colors have low contrast, the code is too small, or the margin is too narrow. Use dark on light, keep the margin and print it larger.
