Question 1

What is a QR code?

Accepted Answer

A QR (“Quick Response”) code is a two-dimensional barcode that stores data — most often a URL, but also plain text, contact details, Wi-Fi credentials, or an email link. A phone camera or scanner reads the pattern of black and white squares and decodes it instantly, which is why QR codes are used on posters, packaging, menus, and payment screens. The code generated here encodes whatever content you enter directly into the image, so scanning it returns exactly that data with no middleman.

Question 2

What’s the difference between static and dynamic QR codes?

Accepted Answer

A static QR code encodes your data directly and permanently — the link or text is baked into the pattern and can’t be changed after printing. A dynamic QR code instead encodes a short redirect URL that points to a destination you can edit later, and which often tracks scans. Dynamic codes are convenient but depend on a third-party service that can log who scans them. This generator produces static codes, which are private and free forever because they contain your data and nothing else.

Question 3

Are generated QR codes free to use commercially?

Accepted Answer

Yes. The QR codes you create here are static images that simply encode your own content, and you’re free to use them anywhere — flyers, products, signage, business cards — including for commercial purposes, with no licence fee or attribution required. There’s no expiry and no account tied to them. Because they’re static, they’ll keep working indefinitely as long as the content they point to (for example, your website) remains live.

Question 4

What do error-correction levels mean?

Accepted Answer

Error correction lets a QR code still be read even if part of it is dirty, damaged, or covered. There are four levels: L recovers about 7% of the code, M about 15%, Q about 25%, and H about 30%. Higher levels add redundancy, which makes the pattern denser but far more robust — useful for printed codes, or if you want to place a small logo in the centre. For on-screen links, M is usually plenty; for print or rugged environments, choose Q or H.

Question 5

Is my data tracked?

Accepted Answer

No. The QR code is generated locally in your browser using JavaScript, so the URL, text, or Wi-Fi password you enter is never sent to our servers or logged. The resulting image contains only the data you typed. Because these are static codes with no redirect, scanning one doesn’t report back to us or to any analytics service — there’s simply nothing in the pipeline to track.
