Information about our QR code generator

You can generate free QR codes on this webstek. A QR code is a two dimensional barcode that stores information ter black and white dots (called gegevens pixels or “QR code modules”). Besides the black and white version, you can also create a colored QR code. For thesis codes to work without problems, make sure the tegenstelling is sufficient and the result is not a negative (ter terms of color). To make your QR code even better, you can also get a QR code with logo.

Create a QR code

Just inject your text, your URL, a SMS or vCard voeling information. The QR code will be generated automatically spil you type. Just click on the “Download” button to get the created QR code picture then (the picture is available spil EPS or SVG vector graphic, spil well spil high-resolution PNG, Toxine or JPEG raster graphics format). You can also embed the QR code directly on your own webstek and use it, just have a look at the code suggested by the “Embed” button. Of course, you can place and use the QR graphic on leaflets, posters, business cards or other products without any costs / for free (including commercial use).

QR codes are the way to go to create a verbinding inbetween the real world products (tagged with the QR code) and the Internet. Mobile, anywhere, anytime. Because QR codes make it so effortless to transfer a web listig to a mobile phone, they provide a significantly lower barrier to visit a webpagina with a wise phone. But you can also work with other texts and gegevens, such spil advertising messages, telephone numbers and even entire business cards ter vCard format. Just encode them with our QR code generator to lightly transfer the gegevens to mobile devices.

Switch your QR code after printing

Our QR code management toneelpodium QR-Server enables you to use dynamic QR codes. Their key feature is that the stored QR code destination address (URL) can be switched at any time and spil often spil you want – even if e.g. your marketing material has already bot printed. Adjust your advertising campaigns at any time or juist errors (for example if a wrong web address wasgoed used). Learn more…

Significant Note: Keep ter mind before printing that it is not possible to convert static QR codes into dynamic QR codes because of technical limitations. This is why wij recommend out QR management solution QR-Server for significant projects and campaigns.

High resolution QR codes, print quality

Wij opoffering QR codes ter print quality – the vector graphic formats EPS and SVG can be downloaded for free and without registration.

The QR code

2D barcodes (a group of barcodes the QR code belongs to) are comparable to common, one-dimensional caf codes spil they are e.g. used on the product packaging at the grocery store. However, QR graphics are able to store much more gegevens, they can include overheen 3000 characters on a very petite space. To create one, the information gets encoded according to ISO/IEC 18004:2006 by a QR generator like ours. The high gegevens density compared to elementary barcodes, the licensing policy of the QR developer / creator Denso Wave plus the broad availability of reading software has helped the QR code to establish itself and shoved technically comparable 2D codes out of the market (see “What is a QR code” for more information on this topic).

The most vooraanstaand use-case for QR codes is the area of mobile marketing. Because there is free QR code software to read QR codes for almost every smartphone with a camera (e.g. iPhone, Google Android, Blackberry, Symbian), QR codes are used spil a listig inbetween offline media such spil paper and websites. The user just needs to scan the code instead of typing long, unpleasant web addresses. However, a QR picture can even be scanned and decoded with older mobile phone cameras and models without Internet access spil QR code readers are available for free for less common and legacy platforms. But the intended use of QR codes and for devices without Internet access is mostly limited to the invoer of business contacts and address gegevens (vCards), trigger phone calls or text messages (see also “Overview of the different QR code types and functionality”). Te particular, QR code business cards are flawless to enable others an effortless and typo-free invoer of your own voeling details. Just print a vCard QR code on your business card.

QR code with logo / pic

The QR code standard includes a sophisticated error correction mechanism (Reed–Solomon error correction). Therefore, it is possible to style some parts of QR codes. For example, our generator is able to switch the foreground and background color of a code and it is also possible to embed a logo, e.g. ter the middle of the QR pic. Embedding content matching logos or icons helps the user see what to expect from the QR code before scanning, even tho’ the QR code contents will not be displayed before scanning the code. Wij have extensive practice with Logo QR ​​codes and you are welcome to voeling us for creating your custom-built logo QR code with colors matching your corporate identity. Learn more…

QR code with vormgeving / style

Beside QR codes with logo, there are also so called Vormgeving QR codes. QR codes with vormgeving are even more modified, they provide a more artsy look than just an image-logo placed te the center of a QR code. Our fucking partner VisuaLead offers numerous functions with which you can let your creativity run wild. Create unique, professional QR codes.

The enlargened appeal of QR codes with vormgeving invites your users to scan the code even more than with a ordinary logo.

A QR code is a two-dimensional code (2D code, matrix code), this means it contains gegevens not only ter one dimension (e.g. horizontally from left to right like the barcodes on the products ter e.g. your grocery store) but also te a 2nd dimension (vertical and horizontal). The acronym QR is brief for “Quick Response”.

QR codes are also often called 2D barcodes. However, this notation is not onberispelijk, because it means “a two-dimensional code consisting of bars” albeit a QR code consists of pixels (so-called “modules”) instead of caf.

The QR code wasgoed invented by the automotive industry. Toyota asked their supplier Denso Wave to develop a barcode to securely and lightly identify components. QR generators were originally used te industrial applications. Therefore, they had to be lightly printable ter form and size spil well spil staying legible when partially ruined or dirty.

Like other codes, the QR code symbol can be captured with imaging devices like a camera and then digitally processed. A software prepares the captured picture gegevens until it can be algorithmically processed according to the QR code standard so the QR code content can be read. This process is assisted by the use of the Reed-Solomon error correction—which is also used for audio CDs to ensure that the gegevens can still be read correctly even with puny scrapes on the surface.

The error correction capabilities are also used for QR codes with logo (often also called “Design QR code” or simply “QR code with picture / icon / logo”). This QR code graphics are faulty “ex works” spil the normally centered placed logo ter a QR code hides some of its gegevens just spil would ordinary filth.

Because of the excellent error correction (they can be read even if up to 30 % of the surface gets demolished) and the high memory capacity (te comparison with other folder codes), the QR code also gained traction outside the automotive industry. Modern mobile phones are powerful enough to run QR code reading software and also usually provide a camera. This combination brought up a multiplicity of possibilities to use the QR code to lightly transfer gegevens without typing to the peoples fresh communication center, the smartphone. Therefore, a widespread use of QR codes became possible with the latest smartphone boom and the enhancing spread of mobile internet.

What is a QR code generator?

A QR code generator is a software which stores gegevens into a QR code (for example a text or a webstek address). E.g. this can be lightly done with our online QR generator goQR.mij: just create a QR code by typing te your gegevens and download it spil high resolution PNG or vector graphic (SVG, EPS). Now you may print your free QR code or embed it on your webstek to make it available to others.

How to create a QR code?

Spelling: “QR-Code”, “QR Code” or “QR code”?

QR Code is the trademark term, the juist English spelling is QR code. Ter German, QR-Code (mind the hyphen!) is used.

Supported QR Generator graphic formats? (PNG, JPG/JPEG, Toxine, SVG, EPS, PDF)

You can uitvoer your created QR code into many formats. goQR.mij offers everything supported by our QR code API for download. Presently supported: PNG, JPG/JPEG, Toxine, SVG, EPS, PDF.

Are QR codes legally protected? What is the licensing policy?

The QR code developer Denso Wave patented the QR code technology and released the QR specification spil an ISO standard (ISO/IEC 18004:2000 and ISO/IEC 18004:2006. However, the patent owners determined not to exercise the rights resulting therefrom. Therefore the use of the QR code technology spil defined by the ISO and JIS (Japanese Industrial Standards) is free of charge. Also a usage registration is not necessary.

The name “QR code” is a registered trademark of Denso Wave Inc. te several jurisdictions (including Japan, the U.S. and many European countries). An suitable notice should be visible when using the brand, is however not necessary if the QR code is only used spil a pattern / picture / graphic / logo / icon (e.g. by including it on a webstek or when printed on a business card, folder, leaflet etc.). More information can be found at the FAQ of QR code developer Denso Wave.

Nevertheless a word of warning: Please be aware that a QR code picture itself may be copyright protected when created by a third party and therefore may incur usage charges or other fees, depending on the license terms of the used QR code generator. Therefore play safe: The QR codes created on goQR.mij are free of charge, for both non-commercial and commercial usage, e.g. by advertising agencies. So make sure to always create your QR codes with our generator.

Is it possible to create different QR codes for the same content?

Yes. Even if all input gegevens and the chosen error correction level (ECC) are identical, there are various graphical representations of a legible and valid QR code with the same content. The reason is that there are eight possible gegevens masks which influence the pattern. Thesis masks exist to prevent some module patterns which are hard to decode.

Not every gegevens mask is truly suitable for every content. However, many QR code generators do not take the testing and determination of the best mask gravely, albeit this may result ter less legible (but still valid) QR codes.

QR code with company logo / photo / branding

Many users are asking if wij can embed an picture or a slogan into a QR code. And yes, it is possible to to customize a QR code with a logo, lettering, picture or some company color schema.

We’re glad to advise you and create print-optimized files quickly and reliably: QR code with logo. Use our service to make your QR codes more efficient. An picture ter the QR code attracts extra attention and directly shows what the code is about.

Is it possible to customize a QR code by using a company logo or icon?

Do QR codes have to be black and white?

No. Most significant is a good tegenstelling inbetween the light and dark modules / pixels. Furthermore, a colorized QR code should be no negative (te terms of color, the actually black pixels / modules have to be darker than the normally white pixels) spil the dark modules / pixels contain the gegevens and a negative will confuse many QR code readers. You can create colored QR codes with goQR.mij for free. Just choose a background and / or a foreground color te the download, embed or shop dialogue.

Switch QR code content (e.g. URL)

Normal, static QR codes are motionless. The gegevens is stored directly te the QR code graphic (hence QR codes are also getting larger and form a more sophisticated pattern if there is more gegevens to store). Therefore, the stored gegevens cannot be switched. Any typo ter an already printed QR code cannot be switched, spil with any other printed material.

Dynamic QR codes are changeable / editable. They can be used with our QR code management toneel QR-Server. Their key feature is that the stored QR code destination address (URL) can be switched at any time and spil often spil you want – even if your e.g. marketing material has already bot printed. Adjust your advertising campaigns at any time or onberispelijk errors (for example, if the wrong web address wasgoed used by mistake). Learn more…

Significant Note: please consider before printing that it is not possible to convert static into dynamic QR codes due to technical limitations. That is why wij recommend out QR management solution QR-Server for significant projects and campaigns.

Can a QR code be edited/switched?

Disambiguation: QR code module or pixel?

The single (normally black and white) elements of a QR code are officially called “modules”, not pixels. This term permits to account for the technical difference inbetween display pixels and the black and white squares of a QR code.

What is a barcode?

Barcodes are—simply put—machine-readable fonts. Their “letters” consists of binary symbols that can be read optoelectronically.

There are different barcode standards. Just spil a person can read a foreign text spil soon spil they learned the alphabet and language, a barcode scanner or its software can read a barcode spil long spil the underlying standard is “understood” (= implemented).

Ter general, barcodes are used spil optical machine-readable labels on objects, containing information about the object on which they are glued. The most popular barcode type is used on the product packaging and can be viewed at every grocery store where they make the Universal Product Code machine readable. Because of their omnipresence, the terms “barcode” is often used synonymously for this UPC-A barcode symbol, albeit there are many other barcode types.

How to read / scan a QR code?

A barcode scanner (or a mobile phone with camera and an suitable reader app) which supports the QR code standard is required to scan a QR code. QR code reader apps are made available by different manufacturers and for different mobile devices, mostly for free.

There are many free QR code reader for Smartphones. However, they differ significantly te terms of usability, scanning speed and standards compliance (ter particular regarding the processing of vCards). Therefore wij provide an overview about recommendable QR code software.

To summarize, there are slew of free QR code readers on the market. Here are the best ones (from our practice, but we’d like to hear your opinion):

Android
Other mobile platforms
  • i-nigma (Hint: visit www.i-nigma.mobi on your mobile device)

Print QR codes (tips)

There is no sophisticated rules to make your QR codes lightly scanable for rather ordinary capturing devices such spil mobile phone cameras. The most significant rules when printing QR codes on everyday materials such spil e.g. business cards and letterheads summarized:

The QR code edge length should be not less than 0.6in/1.5cm (when using vCards 0.8in/2cm), the background color should be brighter than the gegevens pixels (no QR negative te terms of color), Sufficient optical margin around the QR code.

More detailed explanations and valuable printing tips can be found at our “print QR codes” sub-page.

What kleuter of information can be stored te a QR code?

QR codes store binary gegevens. Therefore, possibly all kinds of information can be stored ter a QR code. However, the storage capacity of a QR codes is limited to a maximum of Trio kB (using an 8 bit encoding) which naturally thresholds the possibility to directly store pics and sounds. A verbinding to a webstek which provides the multimedia content normally is the more sensible way to vertoning picture galleries or music via QR code.

You can store brief texts, SMS, all kinds of URLs and websites (Youtube, Facebook, Homepages), voeling details (e.g vCards for QR code business cards, meCard), dates and calendar entries (iCal), telephone numbers, email messages, WiFi access credentials, geo and navigation gegevens and much more. But you have to keep te mind that not every QR code scanner out there is able to process every type of gegevens. You may have a look at out overview about “different QR code types and applications” if you need more information.

Are QR codes standardized?

Yes. The QR code specification wasgoed published by the developer Denso Wave spil an ISO standard (ISO/IEC 18004:2000 bzw. ISO/IEC 18004:2006).

What is Mobile Tagging?

Mobile Tagging describes the process of putting QR codes on real-world objects mark them with some message or connect them to some web pagina. A smartphone can decode / read the QR code with the help of the camera. The term is a reference to the graffiti vaktaal term “Tag”. See “Mobile tagging” for more information.

Is it possible to count the QR code scans (tracking, analytics, measuring)?

Yes. Our QR Management and Tracking solution “QR-Server” offers dynamic, changeable QR codes with analytics (especially suitable for advertising agencies). It wasgoed designed with professional QR users, advertisers and mobile marketing professionals te mind who need accurate analytics—access and scan statistics including geolocation—together with editable QR codes.

Is it possible to track where a QR code wasgoed scanned (geolocation)?

How long are QR codes valid? Do QR codes expire?

From a technical perspective QR codes do not expire or get invalid: The information a QR code offers after scanning is stored te the graphic itself (hence QR codes also get larger and form a more sophisticated pattern if there is more gegevens to store). The stored gegevens cannot be switched and therefore a QR code does not “expire” after a certain time.

Unluckily, there are shady QR code providers and generators, who simply do not store the gegevens entered by the user into the QR code. An example: When you type the web address http://www.example.com, thesis unscrupulous providers store a redirection address like http://[domain-of-the-provider]/www.example.com into the code without notifying the user about it. So after scanning the code, you’re sent to http://[domain-of-the-provider]/ and redirected to the real destination www.example.com afterwards. The business specimen of thesis QR providers normally is to switch off the redirection after a brief time framework. So the QR code “expires” even tho’ neither the QR code symbol strafgevangenis the gegevens it provides were switched. The redirection normally is reactivated after some payment. Sadly, many users are willing to pay because re-printing publicity material, leaflets and things like that often costs more.

However, there is nothing bad about QR code redirects te general (te fact, even our dynamic QR codes are based on redirects to make it possible to switch the target URL after printing). But wij think its bad manners to opoffering a “free” QR service but actually rely on the lack of skill of the customer to take the generated QR codes spil “hostage” because the user created QR codes with expiration date without even noticing it.

Problems with special characters

Wrongly display special characters (e.g. German Umlauts) are normally caused by charset issues. Since the subject matter is not straightforward, wij wrote a dedicated article about it: Special characters within QR codes: what you should know about the charset and QR code encoding.
