About QR Code Tool

The QR Code Tool creates custom QR codes and scans existing ones from images. Businesses print codes that link to menus, websites, and contact details, while individuals decode codes they cannot scan with a camera. To generate, choose the "Generate QR Code" mode, enter a URL, text, or other data, adjust the size, error correction level, colors, and optional logo, and download the result as a PNG or SVG. To scan, switch to "Scan QR Code", upload a photo of the code, and read the decoded content. Generation and decoding both happen in your browser, so your data is never sent to a server.

Frequently Asked Questions

Is the data in my QR codes sent to a server?

No. Codes are generated and decoded locally in your browser. The URLs, text, or Wi-Fi credentials you encode never leave your device.

What can I encode and which formats can I download?

You can encode URLs, plain text, and other data types, then download the code as a PNG or SVG image. For reliable scanning, keep printed codes at least 2 cm square.

Does the QR Code Tool cost anything?

It is completely free with no signup. Generate and scan as many codes as you need.
