QR code generator made for packaging.

No. They are static: the link, text or Wi-Fi details are encoded in the pattern itself, with no redirect service in between, so nothing can be switched off later and nothing tracks your customers. The flip side is that a printed code can’t be edited, so encode a web address you control and will keep.

It depends on how many modules the code has and how far away it is scanned. The generator works out the smallest width for the current code at 0.25 mm per module, including the quiet zone. For scanning from further away, a common rule of thumb is a code at least a tenth as wide as the scanning distance. Shorter links make codes with fewer, larger modules.

Yes. Upload a PNG, JPEG, WebP or SVG and it is placed in the centre at 10–25% of the code’s width. Error correction is set to H, so up to 30% of the code can be covered and still scan, and the finder, timing and alignment patterns under the logo are repainted on top. The image is processed in your browser and never uploaded.

QR codes store extra recovery data. Level L can restore about 7% of the code, M 15%, Q 25% and H 30%. Higher levels survive scuffs, dirt and logos but need more modules, so the code gets denser at the same size. M suits most packs; Q or H is safer on textured or uncoated stock.

It uses the WIFI: format that iPhone and Android cameras recognise: scan it and the phone offers to join the network. The password is stored in the code as plain text, so anyone who scans it can read it. Use a guest network for anything printed.

Dark modules on a light background. The generator refuses light-on-dark codes and anything under 3:1 contrast, because many phone readers can’t decode them. Strong contrast (black, navy, dark green or dark brown on white or cream) scans best, especially under shop lighting.

Instead of covering the centre, your image colours the modules across the whole code while each module’s centre keeps its data. It looks more like artwork but needs a denser code and a larger print size (0.5 mm per module), which the minimum size reflects. Test it with several phones before printing.

Yes. Download the SVG or PDF and place it in your artwork, or open the packaging editor and add a QR code to any panel; it is drawn as vectors in the print PDF and kept clear of folds.
