About the QR Code Generator
A QR code is a two-dimensional barcode that a phone camera reads in an instant. It can hold a web address, plain text, contact details, a Wi-Fi login and more. Type your content, pick a size and colours, and download the code as an image.
The codes this tool creates are static: the information is written directly into the pattern, so they never expire, there is no tracking and no account is needed. The trade-off is that you cannot change the destination after printing, so check your link carefully before printing thousands of leaflets.
For reliable scanning keep strong contrast, ideally dark on light, and leave a blank margin around the code. A code about 2 cm square is about the smallest that scans reliably from a normal distance. Test every code with a phone before you publish it.
Entering https://toolseza.com produces a code that opens the website when scanned. Printed on a business card at about 2.5 cm square it scans easily from arm's length.
Tips for best results
- Shorter text makes a simpler pattern that scans faster, so use a short link where you can.
- Do not invert to light on dark without testing, because many scanners expect dark on light.
