MiscWhat is a QR code
A QR code (Quick Response code) is a two-dimensional barcode that's scanned by a camera and instantly decodes the embedded information: a link, text, contact details, and more. Unlike a regular barcode, a QR code can hold significantly more information thanks to its two-dimensional structure.
Practical uses of QR codes
- Restaurant menus: a link to a digital menu instead of a paper one.
- Business cards and ads: quick access to a website or portfolio without typing an address manually.
- Payments: QR codes for fast transfers or bill payments.
- Wi-Fi access: a QR code can contain data for automatically connecting to a network.
- Product packaging: links to instructions, warranty info, or additional product details.
How to use this generator
Enter a link or text, choose the desired size — the QR code generates instantly. Click "Download QR code" to save the image for printing on business cards, packaging, or anywhere else.
The QR code is created entirely in your browser — no data is transmitted to our servers. However, remember: if the link you encode is later removed or changed, the QR code will continue pointing to the old (possibly invalid) address.
FAQ
Is it safe to generate a QR code online?
Yes, the QR code is generated entirely in your browser — the entered data is never sent to or stored on a server.
Does a QR code expire?
No, the QR code itself doesn't expire — it will always point to the entered address or display the entered text, as long as the linked content still exists.
Can I scan a QR code with a regular phone camera?
Yes, most modern smartphones recognize QR codes directly through the standard camera app, without needing a separate scanner.
