How to Create a QR Code for Free: Step-by-Step Guide
QR codes make it easy to move information from a printed page or screen to a phone. A single scan can open a website, display text, save contact details, connect to Wi-Fi or start a payment. You do not need design experience or special software to make one.
What is a QR code?
A QR code is a square, machine-readable pattern that stores information. A phone camera or QR scanner reads the pattern and shows the stored content. Unlike a traditional barcode, a QR code can hold different types of data, including URLs, plain text, phone numbers, email addresses and network credentials.
How to create a QR code with AeroQR
Open the AeroQR QR Code Generator, choose the type you need and enter the information carefully. For a website, include the complete address beginning with https://. Generate the code, scan the preview and then download it.
- Select URL, text, Wi-Fi, UPI or contact.
- Enter and review the exact information.
- Choose the available size or appearance options.
- Generate and scan the preview.
- Download PNG for common use or SVG for scalable print.
Tips for a reliable QR code
Use a dark code on a light background and leave clear empty space around all four sides. This quiet zone helps scanners identify the code. Avoid stretching the image, placing large artwork over the pattern or using colours with weak contrast.
Always test the final file, not only the preview. Scan it from the actual screen, card, poster or package where it will appear. If it opens a website, confirm that the page is mobile-friendly and the destination is correct.
Common uses
Place QR codes on business cards, menus, product packaging, posters, invoices, event invitations and shop counters. They can link to a portfolio, map location, WhatsApp conversation, feedback form or payment page. Add a short instruction such as “Scan to view menu” so people know what will happen.
Frequently asked questions

Will a QR code expire?
A static QR code normally does not expire, but a link stored inside it can stop working if the destination is removed or changed.
Which file format should I download?
PNG is convenient for websites, messages and office documents. SVG is usually better for professional printing because it scales without becoming blurry.
Can I change a static QR code after downloading it?
No. Create a new code when the encoded information changes.
