Common Mistakes to Avoid
- !Printing a QR code too small - anything under 2.5cm square is unreliable for most phone cameras
- !Using a low-contrast colour combination - dark code on a light background is always the safest choice
- !Encoding a URL that later changes or goes offline, making the code permanently broken
- !Not testing the code before printing or distributing
Limitations
- –QR codes cannot be edited after creation. If the destination URL changes, you need to generate a new code.
- –The more data you encode, the denser and harder to scan the QR code becomes
- –Dynamic QR codes (with redirect tracking) require a third-party service. This tool creates static codes only.
Privacy
QR codes are generated entirely in your browser. No data you enter is sent to any server or stored anywhere.
Frequently Asked Questions
What can a QR code link to?
QR codes can encode URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, and more.
What is the best size for a QR code?
For digital use, 256×256px is sufficient. For print use, 512×512px or 1024×1024px ensures sharp scanning.
What can I encode in a QR code?
You can encode a URL, plain text, a phone number, an email address, an SMS message, Wi-Fi credentials, or contact card details (vCard). URLs are the most common use case.
Will the QR code expire?
No. QR codes generated by this tool encode the data directly. There is no link shortener or redirect server involved. The code will work as long as the destination URL is still live.
What size should I use for a printed QR code?
For reliable scanning, print QR codes at a minimum size of 2.5 cm by 2.5 cm (about 1 inch square). Larger is better for codes that will be scanned from a distance, such as on posters or signs.
Can I customize the color of the QR code?
Yes. You can change the foreground and background colors. Make sure there is enough contrast between them for reliable scanning. Black on white is the most reliable combination.
