What is a QR code generator?
A QR code generator turns text, a web address or structured data such as Wi-Fi details into a square barcode that phone cameras read. This one makes static codes: the content is stored in the pattern itself, so the code never expires, has no scan limit and does not route through a tracking server.
Features
- 11 types: website, text, Wi-Fi, WhatsApp, UPI, email, phone, SMS, contact card, location, event
- 7 dot styles and 6 corner-eye styles
- Solid, linear or radial gradient colours
- Logo with automatic high error correction
- Frames with your own text
- PNG, JPG and SVG up to 4096 px
- Contrast and density warnings before you print
How to use the QR code generator
- Choose what the code should open.
- Fill in the details; the preview updates as you type.
- Pick a quick style or set dots, eyes, colours, logo and frame.
- Scan the preview with two different phones.
- Download SVG for print shops, PNG for most uses or JPG for social media.
Static vs dynamic QR codes
| Static (this tool) | Dynamic (paid services) | |
|---|---|---|
| Expiry | Never | Stops if the subscription ends |
| Scan limit | None | Often limited by plan |
| Change after printing | No | Yes |
| Scan tracking | No | Yes |
| Privacy | Content never leaves your device | Every scan passes their server |
Need to change the target later? Point a static code at a page on your own website and update that page.
Printing size rule of thumb
Make the code at least 2 cm wide, and roughly one tenth of the scanning distance: a poster read from 3 m needs a code about 30 cm wide. Keep the white border (quiet zone) and keep the code dark on a light background.
Frequently asked questions
Do these QR codes expire?
No. They are static codes, so the content is inside the pattern and nothing depends on our servers.
Can I use the QR codes commercially?
Yes, on packaging, print, signage and ads, at no cost and with no attribution needed.
Will adding a logo stop it from scanning?
Not when sized sensibly. The tool switches to the highest error correction (30%) with a logo and caps the logo size within that limit. Always test before printing.
Which file format should I download?
SVG for print shops and designers (sharp at any size), PNG for most uses and transparent backgrounds, JPG for WhatsApp and social media.
Is anything I type uploaded?
No. The code and your logo are processed in your browser and never sent to us.
