🔳 QR Code Generator
Turn any link or text into a QR code — free, instant, no signup.
How This Works
Your QR code is generated entirely in your browser using JavaScript — the text or URL you enter is never sent to our servers. You can download the result as a PNG image to print or share.
Frequently Asked Questions
Do QR codes generated here expire?
No. This tool creates a static QR code that directly encodes your text or URL — it never expires and will
keep working as long as the destination itself is valid.
Guide: understanding your result
- A QR code stores text such as a URL, Wi-Fi details or contact information. Codes made here are static: the content is encoded in the image and does not expire.
- Error correction lets a code survive damage or a logo overlay: level L recovers about 7% of the data, M 15%, Q 25% and H 30%. Higher levels make the code denser.
- Codes are generated in your browser; the content is not sent to our server.
Printing tips
| Factor | Recommendation |
|---|---|
| Minimum size | About 2 × 2 cm (0.8 in) for short URLs; larger for long content or distant scanning |
| Quiet zone | Keep a blank margin of at least 4 modules around the code |
| Contrast | Dark code on a light background |
| Testing | Scan with several phones before printing in bulk |
Common mistakes to avoid
- Encoding a very long URL, which makes the code dense and hard to scan — use a shorter link.
- Printing a code that points to a page you may later delete.
- Scanning codes from unknown sources without checking the URL first.
Frequently asked questions
Can I change where a printed QR code points?
Not with a static code. Point it to a page you control and update that page instead.
