About QR codes
A QR code is a scannable link — point a phone camera at it and the link, text or Wi-Fi login it contains opens instantly. This generator makes codes for URLs, plain text, Wi-Fi networks, email addresses, phone numbers and SMS messages, with custom colors and sizes up to 1024 px, downloadable as PNG with no watermark and no expiry.
How to create a QR code
- Pick the type — for Wi-Fi codes, guests connect just by scanning, no password typing.
- Fill in the details and press Generate QR code.
- Test-scan the preview with your phone (always do this before printing!).
- Download the PNG and drop it into menus, posters, slides, visiting cards or receipts.
Tips for QR codes that scan reliably
- Keep strong contrast — dark foreground on a light background scans best; avoid light-on-dark for print.
- Print at 2 cm (¾ inch) or larger for close-range scanning; bigger for posters scanned from a distance.
- Shorter URLs make simpler, more forgiving codes.
- These are permanent, self-contained codes: they encode your data directly, don't pass through any tracking server, and never stop working.
Frequently asked questions
Do these QR codes expire or have scan limits?
Never. The code contains your data directly — no shortener, no tracking server, no account. It works forever, offline, with unlimited scans, because there's nothing between the scanner and your content.
How do Wi-Fi QR codes work?
Pick the Wi-Fi type, enter your network name and password, and print the code. Guests point their camera at it and join instantly — no typing. The password is embedded in the code, so display it only where guests are welcome.
What size should I print a QR code?
At least 2×2 cm for close-range scanning (menus, cards). For posters, roughly one-tenth of the intended scanning distance — a code scanned from 3 meters should be about 30 cm wide.
Can I change the colors?
Yes — set any foreground and background color. Keep strong contrast (dark on light) or some phone cameras will struggle to read it.
