About this digital tool
A QR code generator turns a link, text, email address, phone number or WiFi details into a square code that a phone camera can scan. Enter your content, choose a size (150, 200, 300 or 400 pixels), and the code appears straight away, ready to download as a PNG image. A QR code stores the content as a grid of black and white squares, and a scanner reads that grid and opens or displays the information. The image is produced by an external image service, so do not enter confidential data such as passwords. QR codes are useful for restaurant menus, business cards, links to websites or profiles, posters and invitations. Always test the code with a phone before you print or publish it.
How to use
- Enter the link or text you want the code to contain.
- Choose a size: 150, 200, 300 or 400 px.
- Check the code that appears and scan it with your phone.
- Download the PNG and test it again before printing.
Frequently asked questions
Does a QR code expire?
No. A QR code simply encodes the content. If the link or information it points to still works, the code keeps working.
What can I put in a QR code?
A URL, plain text, an email address, a phone number or WiFi details in the correct format. Shorter content produces a simpler code that scans more easily.
Is it safe to put private information in a QR code?
Not for confidential data. The image is produced through an external service, and anyone who scans the code can read its content.
Which size should I choose for printing?
300 px is enough for most screens. For large print, choose 400 px or more, keep good contrast and leave a clear margin around the code. Scan a printed test before you publish it.
