A QR code turns any link or piece of text into something a phone camera can open instantly. This generator creates QR codes in your browser for URLs, plain text, phone numbers, email addresses and Wi-Fi-style details, and lets you download the result as a clean PNG image for posters, packaging, menus and business cards.
Settings That Keep Codes Scannable
Size and error correction decide whether a code survives real life. Bigger output is better for print, and higher error correction keeps the code readable even if part of it is scratched, dirty or covered by a logo. You can also change the foreground and background colours, with a sensible warning built into good practice: scanners need strong contrast, so dark codes on a light background are always the safest choice. Every code is generated locally, so the links and details you encode are never sent anywhere.
How to Generate a QR Code
- Type or paste the URL or text the code should contain.
- Set the image size you need — larger for print, smaller for web.
- Pick an error correction level; medium suits most uses.
- Adjust colours if you wish, keeping the contrast strong.
- Download the PNG and test it with your own phone before printing.
Popular Ways People Use QR Codes

Frequently Asked Questions
Do QR codes expire?
No. A code generated here simply contains your text or link, so it works as long as the destination itself stays online.
Why will my code not scan?
Usually low contrast, a very dense code printed too small, or glare on the surface. Increase the size, keep colours dark-on-light and retest.
Can I put a logo in the middle?
With a high error correction level, a small centred logo usually still scans. Test the printed result with several phones before a big print run.
