How to Use This QR Code Generator
This tool supports six of the most common QR code types you'll need day to day:
- Website URL — the most common use, so scanning opens a webpage directly.
- Plain Text — encode any note, message, or piece of information.
- Wi-Fi — let guests connect to your network instantly, without typing a password.
- Email — opens a pre-filled email draft in the scanner's mail app.
- Phone — opens the dialer with the number ready to call.
- SMS — opens a pre-filled text message to a chosen number.
Choose a type, fill in the fields, adjust the size and colours if you like, then click Generate QR Code. Once generated, download it as a PNG image to print, share, or embed anywhere you need.
How QR Codes Work
A QR (Quick Response) code stores data as a pattern of black and white squares arranged in a grid. When a camera or scanner reads the pattern, it decodes the underlying data — a URL, text, or structured information like Wi-Fi credentials — and your device acts on it instantly. Every QR code also includes built-in error correction, which is why a code can still scan correctly even if it's partly smudged, scratched, or has a small logo placed over the centre.
Choosing an Error Correction Level
L (~7%) · M (~15%) · Q (~25%) · H (~30%)
The percentage shows how much of the code can be damaged or obscured and still scan successfully. Use L or M for clean digital use, and Q or H if the code will be printed small, placed outdoors, or have a logo overlaid on it.
Benefits of Using This QR Code Generator
- 100% free and unlimited — generate as many QR codes as you need, with no watermark.
- Works entirely in your browser. Nothing you type — including Wi-Fi passwords — is uploaded to a server.
- No sign-up or expiry. The QR code you download works forever; it isn't a redirect link that can be switched off later.
- Fully customisable. Adjust size, foreground and background colour, and error correction to suit your use case.
- Six formats in one tool — URL, text, Wi-Fi, email, phone, and SMS — so you don't need separate generators.
Frequently Asked Questions
Is this QR code generator really free?
Yes. There's no limit on how many QR codes you can create, no watermark on the downloaded image, and no account or sign-up required.
Do the QR codes expire?
No. This tool creates static QR codes, meaning the data is encoded directly into the image itself. It will keep working indefinitely and isn't dependent on any external service staying online.
Is it safe to put my Wi-Fi password into this tool?
Yes. The QR code is generated entirely inside your browser using JavaScript — your Wi-Fi details, email content, and other inputs are never sent to or stored on any server.
Can I add my logo to the centre of the QR code?
This tool doesn't overlay a logo automatically, but you can add one afterwards in any photo editor. If you plan to do that, choose the Q or H error correction level first so the code stays scannable with part of the centre covered.
What size should I use for printing?
For printed materials like posters or packaging, generate the QR code at a larger size (400px or above) and keep the final printed size at least 2 x 2 cm so it stays easy to scan from a normal distance.
Why did my QR code fail to scan?
This is usually caused by very low contrast between the foreground and background colours, a code that's printed too small, or damage/glare covering more of the code than the error correction level can recover from. Try a higher error correction level or higher contrast colours.
