What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores information such as a website link, text, phone number or Wi-Fi details. Phone cameras can scan it instantly, with no extra app required on most modern devices.

Type or paste your link or text, choose a size and click Generate. When the code appears, use the download button to save it as a PNG image for print or digital use.
Common uses
- Restaurant menus and table ordering
- Business cards and flyers
- Event tickets and check-in
- Product packaging and manuals
- Sharing Wi-Fi access or contact details
Tips for reliable scanning
Keep a quiet white margin around the code, print it at least 2 cm wide, use dark code on a light background, and always test with a real phone before printing large batches. Shorter URLs produce simpler codes that scan more easily.
Frequently asked questions
Do the QR codes expire?
No. The code contains your data directly and never expires. If it links to a website, the code works as long as that website exists.
Is it free for commercial use?
Yes, codes you create can be used anywhere, including print and business materials.
What size should I download?
300–600 px works for most uses. For large prints, choose the biggest size.
