QR-code generator online

A QR code is virtual data encrypted into a two-dimensional square-shaped icon of black and white pixels such as a barcode and read using a smartphone camera or a special application. The designation QR is an abbreviation for the phrase Quick Response.

The QR code was invented by the Japanese company Denso Wave in 1994, which was a subsidiary of Toyota. It was necessary to keep track of manufactured cars and parts, so they developed a way to encode Japanese characters, Latin letters, numbers and other characters in the form of a new type of barcode called a QR code.

A regular barcode could store a small amount of data of letters and numbers, but a QR code could store much more. In addition, the task was to create a recognizable, easily readable format from any angle.

The first option included 7000 characters (including hieroglyphs) and was scanned faster than a barcode. In addition, it met consumer demand for transparency in production, supply, and sales.

So the QR code began to be used in all industries, as the creators abandoned patent rights and made it publicly available. Today, this means that everyone can generate and distribute their own qr code for storing various data (links, text, contacts, access, etc.).

A standard QR code consists of six components:

1. The padding is a white border so that the scanner can determine what needs to be read.
2. Search pattern. Represented as three squares in the lower left and upper, as well as the upper right corners. It is they who tell the scanning device that there is a qr code in front of it and point to its outer boundaries.
3. Leveling pattern. This is the fourth square, which is smaller than the other three. Its function is to ensure that the code is read even when it is upside down.
4. Synchronization bars. Designed in the form of an L-shaped line, which allows you to read even a damaged QR code.
5. The version is a small box near the upper right square, where the version of the code is indicated.
6. Data cells - the rest of the code containing information directly: link, phone number, message, etc.

The qr code works as a means of transmitting data, which can be obtained quickly and easily. That is, if there is no room for a large amount of information, it is convenient to encrypt it into a special code. This is especially beneficial when creating business cards, flyers, tickets, promotional materials, etc.

QR code is a modern way to transfer information. According to Statista, the number of people and businesses using qr codes is growing every year. By 2025, the number of Americans scanning codes is predicted to increase to 99.5 million. But already now they are preferred by smartphone owners as a way to get quick access to marketing and advertising offers, as well as various information.

The top 10 most widely used QR code solutions include: URLs, files, business cards, social networks, HTML, MP3, menus, YouTube, app stores, Facebook. And this is not without reason. First, the number of smartphone owners is growing. Second, network access is ubiquitous. And, finally, in modern gadgets, the function of scanning a QR code is already provided.

There are two main types: static and dynamic.

Static QR codes can be created in unlimited quantities and for free on any generator. But they usually have a time limit and do not allow you to edit information or track the number of scans. Such codes are suitable for personal use, for example, as an identity card. They can be customized to match the corporate identity of the company.

You can make code static for Twitter, Instagram, TikTok, LinkedIn, Spotify, Tripadvisor, SMS, plain text, static URL, bitcoin payments, SEPA transfers, email, Wi-Fi, business card.

This is the kind of QR code you can generate with our QR code generator.

Dynamic is an advanced type of qr. In order to create them on the QR code generator, you need to register. The dynamic type is used in business, advertising or marketing, where you need to completely control your code: update content, change or add a link, fix errors, track the number, time and place of scans.

And dynamic is suitable for PDF, app store, business card plus, social media, Facebook, video, dynamic URL, gallery, event, MP3, coupon, business page, rating, feedback, Google form.

Static QR codes can be valid for an unlimited or limited time period. It depends on which QR generation program was used. For example, some generators provide a 14-day trial period, after which the static code stops working and redirects to a 404 error page. It may also not work if the link has been removed or changed, making it uncrawlable. In other cases, the QR code will be valid as long as you need it.

With our QR code generator you generate a code that is valid without time limits.

As for dynamic ones, they can be changed. You get full control over the code and its contents. It can be edited an unlimited number of times and tracked. But these are all paid services, so to create a QR generator, you will need an annual subscription.

You can recognize a QR code on a smartphone through a standard camera or using one of the mobile applications. It can also be scanned on a computer using a special online service. You will need either a webcam or a downloaded code image.

How to read QR code:

1. Scanning a QR code on a smartphone

To read the code, you need an iPhone with iOS 11 or Android 9.0. The easiest way is to scan it using a regular camera of a mobile device, without using third-party applications, although you can use them if necessary. To recognize the qr code, point your camera at it, click on the pop-up notification, and the content will open in the corresponding application. If this is a link, then in the browser, and if contacts, then in the address book, etc.

You can scan the code on a PC using one of the online services: Qrrd, Decode it!, ZXing, QR Code scanner, etc. Go to the website of one of the listed tools and open the image with the QR code. Drag it into the window or click on the «Select File» button. After that, the content of the code will be displayed on the page.

Is there a limit on the number of QR code scans?

There are no limits on the number of scans, so the QR code can run for as long as you need.

A QR code contains more data than a regular barcode, has built-in error protection, is easier to read and print, and is more secure.

With the spread of the Quick Response code, its functions have also expanded. It has become a universal tool for the development of any business area. A square with pixels allows you not only to report on the characteristics of the product, but also to actively promote the business, collect reviews, and attract customers. One has only to encrypt the necessary information and place the code on the media.

How QR-code generation helps in business development:

1. Interaction with consumers. The key code helps to increase the loyalty and engagement of the audience, to initiate an advertising campaign. It can be used to transfer people to a website, online store, marketplace or application, as well as connect to the Apple App Store, Google Play and Amazon Appstore. It is also convenient to encrypt a documentary video about a product or company, a funny and informative video material in a key code. To improve customer relationships, use a QR code generator to create a feedback link on your website or Google Business Profile.
2. Quick transfer to social networks. If you want to increase your social media following, use the QR code to redirect your audience to Facebook, Twitter, Instagram, YouTube and other platforms. So your audience will be able to follow the news of the company.
3. Comfort. To attract consumers, make interaction with the company quick and convenient. QR codes for business pages, contactless payments, ratings, communications will help you. You can create a QR code for email, SMS, coupons with great deals. For cafes and restaurants – link to the menu.
4. Brand design. QR codes easily adapt to any brand. They don't have to be black and white. To stand out and increase company recognition, you can make a QR code in different shades or corporate colors, add branded elements, a logo.
5. Profitability. Generating QR codes online or using other services won't take long and won't cost all the money in the world. And it will bring much more benefits for business promotion.
6. Dynamism. Kewar codes as carriers of links to a particular resource allow users to quickly receive up-to-date information. That is, when changing the content on the site, the code does not have to be redone.

The use of QR codes helps businesses build communication with the audience, increase awareness, loyalty and trust. This method of promotion will show consumers that they are a modern company that follows trends, introduces new technologies and keeps up with the times.

To generate a qr code, you will need an online QR code generator offered by Welovebrands. This is a simple and understandable resource that allows you to generate pixel patterns in three steps in minutes.

How online QR generator works:

1. Select a code type. You need to choose from the available options the one that suits you.
2. Enter content. In the field you need to insert text or a link to your resource.
3. QR customization. You can choose a color, corner style, add a logo and a frame to get the qr code that meets your needs, and then download the finished version.

For iOS and Android the creation procedure is the same. The generator helps to obtain high-resolution qr codes with a design that matches the corporate identity of the company, which can be used both for printing and for commercial purposes.

A QR code can be used in marketing to increase the number of clicks to a resource. Appearance is extremely important for advertising campaigns. A color code draws more attention, but too bright can turn off, so strike a balance. Avoid muted tones as these codes will be difficult to scan. In addition, keep the square shape, so you will increase the speed of loading content. And be sure to check the information before printing.

A QR code on a business card and other printing is a way to make it more modern and provide more information to consumers or partners. By uploading videos, music, photos, you can acquaint the audience with the features of the activity, benefits, samples of work, as well as push them to take action and allow them to constantly stay in touch with you.

A QR code for a restaurant and cafe will allow you to unlock all the possibilities of a digital menu in order to attract customers, save time, and increase brand awareness. The code can be placed on flyers, posters, stickers - where it will be easier for visitors to scan it.

QR code for YouTube is suitable for advertising. The user does not have to follow the links - he will immediately open your video presentation or video. Creating a qr code from a video is suitable for those who need to promote their YouTube channel. Here you can use bold colors in the pattern.

A QR code for PDF is a way to make a document more convenient to send (not via e-mail or instant messenger). You will be able to talk about the capabilities of the product, prescribe instructions, post reviews, recommendations. Therefore, such a code is convenient to use in the trade, educational environment, construction industry, catering, postal deliveries, etc.

QR codes are also used to link directly to apps from the App Store or Google Play, verify accounts and data online, provide Wi-Fi access, send and receive payment information, and even headstones so people can learn more about the deceased.

However, there are products on which the QR code cannot be found. For example, when marking wires, cables or any other thin products, it is much more convenient to use a regular barcode.

Size matters. A large QR code is more visible, making it easier to scan, and easier to read. The minimum allowable code size is 20x20 mm.

There are several types of code according to the methods of encoding data. They can contain different amounts of information.

• Digital encoding allows you to record up to 7089 characters (numbers from 0 to 9).
• Alphanumeric encoding allows storage of up to 4296 characters (numbers, Latin letters, simple characters).
• Binary encoding holds up to 2953 characters (ISO-8859-1).
• Kanji allows only 1817 characters to be stored as Japanese characters.

Thus, two versions of the code are distinguished: Micro QR Code and Standard QR Code. The first option can represent up to 35 digits or 21 alphanumeric characters, while the second option can represent up to 7089 digits or 4296 alphanumeric characters.

The online QR code generator allows you to create high quality static qr codes, design them in accordance with the corporate style, select frames, symbols, colors and gradients.

QR codes should ideally be scanned on any device, that is, be compatible with different cameras and operating systems. But they don't always work. There are several reasons why a qr code cannot be scanned.

6 mistakes affecting QR Code operation:

• Color inversion. Don't flip the color scheme (black background and white foreground). Most scanners simply cannot process such a qr code.
• Lack of contrast. Make sure there is sufficient contrast between the background and foreground. The classic version is black and white. But if you want to design a QR code in branded shades, it is important that they are not too similar, otherwise the scanner simply does not read them.
• Low quality. Avoid blur. Make an image with enough resolution so that it looks sharp when scaled. It is difficult for scanners to determine the boundaries of fuzzy qr codes, which makes recognition difficult.
• Small size. Don't make the code too small. The minimum size must be at least 2x2 cm. You should also check that all pixels are visible.
• A lot of information. The more content in the QR code, the smaller the pixels and corner elements will be. And this can create problems when reading. Therefore, do not overload the code with data. But if you still need to put a lot of information, consider generating dynamic code.
• No frame. For the scanner to correctly read the information, it is important to see the corner elements as separate objects, so make a frame around the QR code.

Check the functionality of the code on different devices and applications. Also be sure to scan it yourself in various ways before printing. After all, a mistake can cost you dearly.

The qr code can be printed in .png or .svg high resolution.

While most free QR generators use low-res vector formats, high-res .png files are fine for printing. But if you want to be able to edit further, use .svg instead. This format includes all design settings and can be used in most vector graphics programs. In addition, it is optimal for printing QR codes.

Our online QR generator allows you to create static codes for free. You can generate qr code for URL, vCards, Plain Text, Email, SMS, Twitter, Wi-Fi and Bitcoin. Once created, it can be used for as long as needed.

At the same time, the free QR generator is not suitable for everyone, because such codes have a minus: the generated static code cannot be corrected. That is, if you make a mistake, you will need to go through the generation procedure again. Therefore, be sure to check the operation of your qr code on several scanners before sending the image to print. As for dynamic code, while our free resource does not provide such a function.
