Why use this qr code generator?

QR Code Generator creates a PNG QR code for a URL or text with selectable output size and error-correction level. Generation happens in your browser.

Example

Create a 512 px QR code for a company website, choose high error correction and test it with a phone before placing it on printed material.

Important note

Always scan the final QR code from the actual medium where it will be used. Dense content, low contrast, damage or very small print size can reduce scan reliability.

How to use it

Start with the inputs shown above, review the assumptions or options, then generate the result. Where the tool creates a file, keep the original until you have opened and checked the downloaded output.
