QR Code Generator

What is a QR code

QR code stands for 'Quick Response'. It is a way to encode information in a graphic form understandable to machines and convenient for quick recognition by cameras, for example, in mobile phones. QR code is one of the types of barcodes. It was created in Japan in 1994 by the company Denso Wave to track components in the automotive industry. The invention quickly gained popularity due to its ease of use and versatility. Using a QR code, you can encode any information, for example: text, phone number, geolocation, a link to a website, or a business card. QR codes are used for banking transactions, in marketing, publications, design, they automate technological processes, warehouse accounting, and much more.

How to create a QR code

Very simple! There are countless different online QR code generators. Our QR code generator offers the simplest possibilities to quickly and for free create a QR code, however, there are many other generators with more advanced features. For example, some allow you to add a logo, gradient, or even a background image. However, these customizations can complicate the reading of QR codes, and may even make it unreadable. Nonetheless, one of the key features of QR codes is their high degree of damage resistance.

How to scan a QR code

To scan QR codes with your phone's camera:

• Open the camera on your device.
• Point the camera at the QR code so that it is in the center of the frame.
• Wait until your device recognizes the QR code. Usually, this happens automatically.
• After recognizing the QR code, information or actions related to this code will appear on the screen (for example, opening a web link, adding a contact, etc.).

If your device does not automatically recognize QR codes, you can download a QR code scanning app from your app store and use it for scanning.

Do QR codes have an expiration date

No, our QR codes do not have an expiration date. QR codes created using our generator are static and do not stop working after a certain time. Because our QR code is just a way of presenting information. As long as the information is unchanged, your QR code will work. The only moment - after creation, you will not be able to edit the contents of QR codes.

How do static QR codes differ from dynamic ones

Static QR codes contain the information you want to encode, only in graphic form. If after creating a QR code, you want to change this data, you will have to generate a QR code anew. Static QR codes are perfect for tasks where content cannot change: for example, an email address or phone number. However, they can be inconvenient if, for example, you are printing a batch of books with a QR code linking to a website or video, and you are not sure that you will not need to change the website link or have to re-upload the video to another hosting.

Dynamic QR codes, unlike static ones, allow you to change the information associated with the QR code after its creation. This happens because not your direct content is coded, but a special link to the service with which you generated the QR code. When scanning a QR code, the application goes to this link on the service page, which in turn redirects or delivers your content. In the personal account of such services, you can at any time change the information that will open at this link, thus maintaining its relevance. Usually, this is not free. Dynamic QR codes require an internet connection for redirection and are often used for marketing campaigns, tracking, analytics, and places where information can change, for example, for promotions, events, or restaurant menus.

Are QR codes suitable for high-resolution printing

As a rule, a vector format is used for high-quality printing. Our generator allows you to create a QR code in a universal vector format SVG, which is ideal for printing. If you need to use raster formats, such as JPG or PNG, then set the maximum resolution in pixels. To ensure the QR code is easily scannable, it must be no less than 3×3 cm. Do not place several QR codes close to each other. Do not forget to check the QR code before printing.

Can I use the QR code generator for commercial purposes

All generated QR codes are completely free and can be used for commercial and indeed any purposes.

Do you save my data

We do not save and do not use it in any way. QR code generation happens in your browser, no data is sent to us on the server.

Why doesn't my QR code work?

Numerous factors can lead to the malfunction of a QR code. First of all, check the correctness of the entered information. Sometimes, even minor typos in the URL can disrupt the functionality of the QR code. If your QR code includes a large amount of data, it is recommended to minimize this information to facilitate the scanning process of the code. One of the problems can be the presence of a logo inside the QR code; its removal can improve the situation. Moreover, it is important to ensure a high contrast between the background color and the elements of the QR code, while the elements of the code should be significantly darker than the background. This guide explains the main reasons why QR codes may not function properly.
