📱 Free QR Code Generator

No. These are static QR codes, which means your link, text or contact details are encoded directly in the pattern. There is no redirect service and no account behind them, so nothing can expire or be switched off. Services that sell "dynamic" codes route every scan through their own server, which is why those codes stop working when a subscription ends. A static code will work for as long as the destination you encoded still exists.

Not with a static code, because the destination is part of the pattern. The practical workaround is to encode a URL you control, such as yoursite.com/menu, and update or redirect that page whenever you need to. You keep full control, pay nothing, and every printed code keeps working. This is the approach we recommend for packaging, signage and anything printed in large quantities where reprinting would be expensive.

It is as safe as writing the password on a card, because anyone who scans the code can see it. That is fine for a guest network, and much better than reading the password out loud. Because this generator runs in your browser, the password is never uploaded or stored by us. For business premises, put guests on a separate guest network and keep your main network's password out of any printed code.

Use PNG for anything on screen: websites, presentations, emails and social posts. Use SVG for print, especially anything larger than a postcard, because SVG is a vector format that scales to any size without blurring. Most print shops and design tools such as Figma, Illustrator, Canva and Inkscape accept SVG directly. If you are unsure, download both and keep the SVG as your master file for future print jobs.

The usual causes are low contrast, a code printed too small for the scanning distance, a missing blank margin around the edges, or a glossy surface reflecting light. Inverted colours, with a light code on a dark background, also confuse some older scanners. Try dark-on-light colours, a larger print size and at least four modules of white space around the code. Then test again on two different phones before reprinting anything.

Yes, with care. This tool uses error correction level H, which tolerates about 30% damage, so a small logo covering the centre of the code usually still scans. Keep the logo under roughly a fifth of the code's width, never cover the three large corner squares, and add the logo in a design tool after downloading the SVG. Always test the final artwork on several phones, because logos eat into the code's safety margin.

It encodes a wa.me link containing your phone number and, optionally, a pre-filled message. When someone scans it, WhatsApp opens a chat with you and the message already typed, ready to send. Enter the number in full international format with the country code and no spaces or dashes. The scanner still has to press send, so nobody is messaged without choosing to, and your number is visible to anyone who scans.

No. The generator runs entirely in your browser, so there are no accounts, credits, watermarks or daily caps. Make as many codes as you need for menus, tables, products or events. You can also use the codes commercially, on packaging, ads and printed materials, without attribution. The only practical limit is the QR format itself, which holds up to 4,296 alphanumeric characters in the largest version.

Yes. Since iOS 11 and modern Android versions, the built-in camera app reads QR codes with no extra app, so scanning takes a second rather than a download. Restaurants, ticketing, payments and parcel lockers have made it routine. The bigger question is whether the code is worth scanning: a clear label such as "Scan for the menu" or "Scan to join Wi-Fi" consistently beats an unexplained square printed in a corner.
