Question 1

Will adding a center logo break the QR code?

Accepted Answer

No. The tool uses high error correction (level H), which means up to 30% of the code can be obscured and it will still scan correctly. The center logo is sized to stay within this limit.

Question 2

What export formats are available?

Accepted Answer

You can export as PNG (2x pixel ratio for crisp prints) or PDF. There's also a mobile layout option that creates a vertical design with a title below the code.

Question 3

How much data can a QR code store?

Accepted Answer

A standard QR code can store up to about 4,296 alphanumeric characters or 7,089 numeric digits. In practice, shorter content produces simpler codes that scan more reliably. This browser-based tool generates your QR code client-side and shows a live preview so you can verify scannability before exporting.

Question 4

Can I add my company logo to a QR code?

Accepted Answer

Yes. This tool lets you place a custom center icon or logo on your QR code. It uses high error correction (level H) to ensure the code remains scannable even with the logo covering part of it. The logo is added entirely in your browser with no upload required.

Question 5

What is QR code error correction?

Accepted Answer

Error correction adds redundant data to a QR code so it can still be read even if part of it is damaged or obscured. There are four levels: L (7%), M (15%), Q (25%), and H (30%). This tool uses level H by default, allowing up to 30% of the code to be covered by a logo while remaining scannable.

Question 6

Do QR codes expire?

Accepted Answer

No. QR codes generated by this tool are static and never expire because they encode the data directly into the code pattern. As long as the content the code points to (such as a URL) remains active, the QR code will work indefinitely. Generation happens entirely in your browser.
