QR code generator
Make a QR code for a link, text, phone number or UPI payment link and download it as a PNG. Created in your browser; nothing is uploaded.
Runs in your browser. Nothing you enter is uploaded.
What it does
Type a web address, some text, a phone number or a payment link and get a QR code that any phone camera can scan. The code is drawn on your own device and the image is yours to use on posters, menus, visiting cards and invitations.
How to use it
- Type or paste what the code should contain. For a website, include https://.
- Choose the error-correction level. Medium suits most uses; choose High if the code will be printed small or may get scratched.
- Choose the size and colours. Keep the dark colour clearly darker than the light one.
- Download the PNG and test it with your phone before printing.
Worked example
Entering https://genesisforge.in makes a code that opens that site. Entering tel:+911234567890 makes one that offers to call the number.
How it works
The text is converted to bytes and packed into a grid of dark and light squares, along with extra error-correction data (Reed-Solomon codes) that lets a scanner rebuild the message even if part of the code is damaged. More text or a higher correction level needs a bigger grid, so long links make denser codes. The three large squares in the corners tell the scanner where the code is and which way up it is. This page uses the open-source qrcode-generator library by Kazuhiko Arase, loaded from this site.
Questions
Do these QR codes expire?
No. The content is stored in the image itself and nothing passes through our servers. It works as long as the link inside it works.
Can I change where the code points after printing?
No. This is a static code. To change the destination you need a new code, or a link you control that redirects.
Why will my code not scan?
Usually low contrast, a code printed too small, or no white margin around it. Keep a quiet border of about four squares on every side.
Can I make a UPI payment QR?
A UPI link starting with upi://pay?pa= and your UPI ID will scan in UPI apps. Check the code with a small payment to yourself before sharing it, and never share a code made by someone else as your own.
Is QR Code a trademark?
Yes. “QR Code” is a registered trademark of DENSO WAVE INCORPORATED.
