QR CODE GENERATOR

No. The QR codes generated here are 'Static.' The text or URL you enter is mathematically drawn into the image itself. It does not rely on our servers to redirect traffic. As long as the URL you point to remains active on the internet, the QR code will work forever.

Technically, a standard QR code can hold about 4,000 alphanumeric characters. However, as you add more text, the black-and-white grid becomes incredibly dense and microscopic. Highly dense codes are very difficult for older phone cameras to scan. We strongly recommend keeping URLs and text as short as possible.

No. Because this is a static QR code, the destination data is permanently hardcoded into the visual grid geometry. If you make a typo in the URL or need to change the destination website later, you must generate a brand new QR code and replace the old image.

The most common issues are: 1) The URL is too long, making the grid too dense. 2) Poor contrast (e.g., dark blue on a black background). 3) You didn't leave a blank white 'Quiet Zone' border around the edge of the code. 4) The printed size is too small for the distance you are trying to scan from.

If you are printing on standard business cards or flyers, the Medium (250x250) or Large (500x500) PNG is perfectly sharp. If you are printing on large posters, banners, or billboards, select the HD (1000x1000) option to ensure the sharp edges of the grid don't blur when scaled up.

A QR code itself is just a square of text; it cannot execute code. However, a QR code can contain a URL that points your browser to a malicious website containing phishing scams or malware downloads. Always check the URL preview on your phone before tapping to open the link.

Those are 'Positioning Detectors.' They allow the camera software to instantly identify the bounds of the code and determine its rotation. This is why you can scan a QR code upside down, sideways, or at a severe angle, and your phone will still instantly read the data.
