Check that this QR code scans correctly
You can change prices and dishes without reprinting a paper menu. Paste the address of your online menu page or listing into the URL tab and a QR code linking to your menu is created instantly. Tap the "Restaurant menu QR" preset above to automatically set a size and margin that work well on a table. It is especially handy for cafes whose menus change often, or for restaurants where prices move with the market.
The question "what's the Wi-Fi password?" disappears with a single Wi-Fi QR code. Enter the network name (SSID) and password in the Wi-Fi tab, and guests connect to your network just by pointing their camera, with no password to type. The password you enter is never sent to a server and is processed entirely inside your browser. To grow followers, use the Social tab to turn your channel or profile link into a QR code customers can scan.
If a QR code prints blurry, it will not scan. When printing large, such as on menus or posters, use "Save PNG (HD x4)" instead of the standard PNG, or save as a vector SVG that stays sharp at any size. Even when you change the colors to match your brand, keep strong contrast between a dark foreground and a light background. Before printing, run a quick scan test with a real phone so you do not discover problems later.
A QR code (Quick Response code) is a two-dimensional barcode that a smartphone camera can scan instantly to read information. It can hold many types of data, such as a website URL, contact details, Wi-Fi credentials, or a plain text message. QR codes act as a bridge from offline media to digital content on restaurant menus, business cards, product packaging, posters, and flyers. For small businesses they are a highly useful marketing tool for attracting customers, sharing information, and offering contactless service.
Yes, most modern smartphones read colored QR codes without any problem, as long as there is enough contrast between the foreground and background colors. Combinations that are too light or use similar colors can lower the scan rate, so we recommend a dark foreground with a light background. Even when you use brand colors, setting the error correction level to H keeps the code reliably scannable.
Placing a logo in the center of a QR code covers part of the data area and can make scanning harder. To compensate, set the error correction level to H (30%), which allows the code to be restored even if 30% of the data is damaged. Keep the logo size within 10-20% of the whole QR code and add white padding to greatly improve the scan rate. This tool automatically switches to level H when you add a logo.
For reliable scanning in print, a QR code should be at least 2x2cm (about 0.8x0.8in). For business cards or small labels, 2cm works; for menus and posters, 3-5cm is recommended. Use the HD x4 PNG export to get a crisp QR code in print. After printing, always run a scan test with a real smartphone.
When you generate a Wi-Fi QR code, customers or visitors can connect to the network automatically just by scanning it, without you sharing the password directly. This improves both security and convenience. Use it in cafes, restaurants, offices, hotels, or anywhere with public Wi-Fi by placing it on a table stand or wall. Both Android and iOS support Wi-Fi QR codes in the default camera app.
QR codes themselves never expire. As long as the URL or information they contain is still valid, they can be scanned and used at any time. However, a URL QR code stops working if the linked web page is deleted or the URL changes. For long-term use, point to a stable URL, and when something needs to change, generate and replace it with a new QR code. vCard and Wi-Fi QR codes must be regenerated whenever the information changes.
