QR Code Generator
Turn any link or text into a downloadable QR code — generated locally, with no watermark.
What is the qr code generator?
A QR (Quick Response) code is a two-dimensional barcode that stores text — most often a URL — in a grid of black and white squares that any phone camera can read. This generator converts your text or link into a QR code image you can download as a PNG and print or share. Everything is produced in your browser, so there are no watermarks, sign-ups or uploads.
How it works
Your input is encoded into the QR specification's data format, then protected with Reed–Solomon error correction so the code still scans even if part of it is dirty or obscured. The resulting matrix of modules is drawn onto a canvas at the size you choose and exported as a PNG. A higher error-correction level adds redundancy (useful if you'll print small or place a logo over the centre) at the cost of a denser pattern that needs a clearer scan.
Worked example
Type your website address, pick a 512-pixel size and a medium error-correction level, and the QR code renders instantly. Download the PNG and print it on a flyer; a phone camera opens your link in a second. If you expect the print to get scuffed, switch to a high error-correction level so the code keeps working even with minor damage.
Frequently asked questions
Do the QR codes expire?
No. These are static codes that encode your text directly, so they never expire and don't depend on any service staying online.
What does the error-correction level do?
It adds redundant data so the code can still be read if partially damaged or covered. Higher levels are more robust but make the pattern denser.
Can I encode more than a URL?
Yes. Any text works — phone numbers, Wi-Fi details, plain notes or contact info — though very long text produces a denser, harder-to-scan code.
Is there a watermark or size limit?
No watermark and no artificial limit. You choose the pixel size and download a clean PNG.
Is my data sent anywhere?
No. The QR code is generated entirely in your browser; your text is never uploaded.
