How to Make a QR Code Free Online
A QR code turns a link or a piece of text into a square pattern that any phone camera can scan — no typing, no mistakes. It is the easiest way to share a website, a Wi-Fi password or a short message on a poster, a card or a screen. This guide shows how to make a QR code for free, in your browser, and download it as a PNG. Use the free QR code generator below to make your QR code in seconds.
How to Make a QR Code — step by step
- Enter the text or link in the “Text or link” field.
- Enter the size in pixels in the “Size (px)” field.
- Press “Generate QR code”.
- Press “Download PNG” to save the code as qr-code.png.
Tips
- Test before you print. Scan the code with your own phone to make sure it opens the right link.
- Size matters in print. Choose a larger size for printed codes so phone cameras can read them, and keep the print at least a few centimetres across.
- Keep contrast high. A dark code on a light background scans best — avoid busy backgrounds behind the code.
Frequently asked questions
What can a QR code contain?
Text or a link. Scanning it opens or shows exactly what you entered.
Will the QR code still work if printed small?
A QR code printed too small can become hard for phone cameras to read. Print it at least a few centimetres across, with clear contrast and no other graphics touching it, and test it with a phone camera before printing many copies.
What size should I choose?
220 pixels works well on screen. For print, choose a larger size so the code stays sharp when printed, and test it by scanning the printed copy.
