QR codes are everywhere — on restaurant menus, business cards, product packaging, and event flyers. Creating one used to require expensive software. Now you can generate a QR code for free online in under 10 seconds, with no account required.
A QR code (Quick Response code) is a two-dimensional barcode that smartphones can scan with their camera. It can encode various types of data — most commonly a web URL — and redirect users to a website, show contact information, or connect to a WiFi network automatically.
| Type | What It Does | Best For |
|---|---|---|
| URL / Website | Opens a webpage when scanned | Marketing, menus, events |
| Plain Text | Displays text on screen | Instructions, notes |
| Opens email app with pre-filled address | Contact pages, forms | |
| Phone Number | Opens phone dialer | Business cards |
| WiFi | Auto-connects to a network | Cafes, offices, hotels |
| vCard / Contact | Adds contact to phone book | Networking events |

Generate QR Code Free →One of the most useful QR code types is the WiFi QR code. Instead of telling guests your WiFi password verbally or writing it on a card, they simply scan the QR code and their phone connects automatically.
To create a WiFi QR code, you need:
Add a QR code to your business card that links to your LinkedIn profile, portfolio, or website. When someone scans it, they instantly get all your contact info — no typing required.
A static QR code (one that directly encodes a URL or text) lasts forever — there is no expiry. The code will work as long as the destination URL is active. If you're linking to a webpage, make sure that page stays live.
QR codes can be printed at almost any size, but too small and smartphones will struggle to read them. Here are practical guidelines:
Always test your QR code at the intended print or display size before mass printing. Scan it yourself from the expected scanning distance to confirm it reads correctly.
Static QR codes — like those generated by our free tool — cannot be edited after creation. The data is encoded into the pattern itself, so changing the destination requires generating a new QR code. If you need an editable QR code (where the destination URL can be changed without reprinting), look for a "dynamic QR code" service. These use a redirect URL — the QR code always points to the same redirect, but the redirect can be changed. Dynamic QR codes usually require a paid subscription to a QR management platform.
For most personal and small business uses, static QR codes are perfectly sufficient and free.
QR codes have become essential tools across many sectors:
No. Most modern smartphones (iPhone and Android) can scan QR codes directly with the built-in camera app. Just open Camera, point it at the QR code, and tap the notification that appears. No separate app needed.
Yes — QR codes have built-in error correction. A standard QR code can still be read even if up to 30% of it is damaged, dirty, or covered. This is why logos are often placed in the center of QR codes without breaking them.
