QR Code Generator

Generate QR codes from any URL or text

Updated May 20, 2024

What is the QR Code Generator?

Generate custom, high-resolution QR codes from any text or URL directly in your browser. Our QR Code Generator is a fast, privacy-focused tool that requires no sign-up and works entirely offline. Whether you need a QR code for a website link, contact information, or plain text, this tool provides full customization. Adjust the foreground and background colors, set the error correction level, and add a quiet zone margin to ensure scannability. Export your QR code as a scalable SVG vector image or a high-resolution PNG with a transparent background for seamless integration into any design.

This QR code generator processes your data entirely on your device using standard QR encoding algorithms. Here is a breakdown of how it works: Data Encoding : The input text or URL is encoded into byte mode. The tool automatically selects the smallest QR version (Version 1 to 5) that can accommodate your data based on the chosen error correction level. Error Correction : Using Reed-Solomon error correction, the tool adds redundant data to your QR code. This ensures that even if the code is partially damaged or obscured, it can still be scanned successfully. You can choose from four levels: L (Low, 7%), M (Medium, 15%), Q (Quartile, 25%), and H (High, 30%). Matrix Placement & Masking : The encoded data bits are placed into a 2D matrix along with functional patterns (finder, alignment, and timing patterns). The tool evaluates 8 different mask patterns and automatically applies the one that minimizes visual complexity, ensuring optimal scannability. Rendering & Export : The final matrix is rendered as an SVG path, allowing for infinite scalability without quality loss. For PNG exports, the SVG is drawn onto a canvas at your specified resolution, supporting transparent backgrounds if desired.

Convert a website link into a scannable QR code for print or digital sharing.

Are the generated QR codes free to use?

Yes, all QR codes generated with this tool are completely free to use for both personal and commercial purposes. There are no hidden fees, and the codes never expire.

Is my data secure when using this QR code generator?

Absolutely. This tool runs 100% client-side in your browser. Your text, URLs, and other data are never uploaded to any server, ensuring complete privacy and security.

What is error correction and which level should I choose?

Error correction allows a QR code to be read even if it is partially damaged or dirty. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. For standard digital use, M is recommended. If you plan to print the QR code or place it in a complex environment, choose H.

Can I create a QR code with a transparent background?

Yes. You can toggle the "Transparent background" option, which will generate a PNG with a transparent background. Note that SVGs naturally support transparency if no background color is set.

Why is my QR code not scanning?

Ensure there is enough contrast between the foreground and background colors (dark colors on light backgrounds work best). Also, check that your error correction level is appropriate for the environment where the code is placed, and avoid distorting the aspect ratio when printing.
