Mero Tool's QR Code Generator helps you create professional QR codes instantly. A QR (Quick Response) code is a two‑dimensional barcode that stores information as a pattern of squares which can be scanned by smartphone cameras and other devices. Whether you need to share website links, WiFi credentials, contact information or any text content, our tool provides a simple solution with advanced customisation options.
QR codes encode data such as URLs or plain text into a matrix of black and white squares. When you scan a QR code with your phone’s camera or a dedicated QR reader, the device decodes the pattern back into usable information. Because they can store more characters than traditional one‑dimensional barcodes and be scanned from any angle, QR codes are widely used for payments, product packaging, event tickets and more.
Always exercise caution when scanning QR codes from unknown sources. Malicious QR codes can direct you to phishing websites, trigger unwanted downloads or attempt to harvest personal information. Before scanning, make sure the QR code is from a trusted organisation, and verify the URL that appears on your screen before proceeding. We also recommend using a QR scanner that previews the link before opening it.
Our QR Code Generator supports multiple types including:
Yes! You can upload a PNG image of your logo which will be placed in the center of the QR code. We recommend using a simple logo with good contrast for best scanability.
Our generator can create QR codes up to 500x500 pixels. For most use cases (business cards, flyers), 200-300px is sufficient. Larger sizes are better for posters or signage.
Standard QR codes can hold up to 3KB of data. For most use cases (URLs, contact info), this is more than enough. Very long text may require a higher error correction level which we handle automatically.
No! You can generate unlimited QR codes with our free tool. There are no restrictions or hidden costs.
