QR generators were originally used in industrial applications. Toyota asked their supplier Denso Wave to develop a barcode to safely and easily identify components.

The QR code was invented by the automotive industry. However, this notation is not correct, because it means “a two-dimensional code consisting of bars” although a QR code consists of pixels (so-called “modules”) instead of bars. QR codes are also often called 2D barcodes. The acronym QR is short for “ Quick Response”. your grocery store) but also in a second dimension (vertical and horizontal). horizontally from left to right like the barcodes on the products in e.g. Just print a vCard QR code on your business card.Ī QR code is a two-dimensional code (2D code, matrix code), this means it contains data not only in one dimension (e.g. In particular, QR code business cards are perfect to enable others an easy and typo-free import of your own contact details. But the intended use of QR codes and for devices without Internet access is mostly limited to the import of business contacts and address data (vCards), trigger phone calls or text messages (see also “ Overview of the different QR code types and functionality”).

However, a QR image can even be scanned and decoded with older mobile phone cameras and models without Internet access as QR code readers are available for free for less common and legacy platforms. The user just needs to scan the code instead of typing long, unpleasant web addresses.

iPhone, Google Android, Blackberry, Symbian), QR codes are used as a link between offline media such as paper and websites.

Because there is free QR code software to read QR codes for almost every smartphone with a camera (e.g. The most prominent use-case for QR codes is the area of mobile marketing. The high data density compared to simple barcodes, the licensing policy of the QR developer / creator Denso Wave plus the wide availability of reading software has helped the QR code to establish itself and pushed technically comparable 2D codes out of the market (see “ What is a QR code” for more information on this topic).

To create one, the information gets encoded according to ISO/IEC 18004:2006 by a QR generator like ours. However, QR graphics are able to store much more data, they can include over 3000 characters on a very small space. used on the product packaging at the grocery store. Just encode them with our QR code generator to easily transfer the data to mobile devices.ĢD barcodes (a group of barcodes the QR code belongs to) are comparable to common, one-dimensional bar codes as they are e.g. But you can also work with other texts and data, such as advertising messages, telephone numbers and even entire business cards in vCard format. Because QR codes make it so easy to transfer a web link to a mobile phone, they provide a significantly lower barrier to visit a site with a smart phone. QR codes are the way to go to create a link between the real world products (tagged with the QR code) and the Internet. 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). You can also embed the QR code directly on your own website and use it, just have a look at the code offered by the “Embed” button. Just click on the “Download” button to get the created QR code image then (the image is available as EPS or SVG vector graphic, as well as high-resolution PNG, GIF or JPEG raster graphics format). The QR code will be generated automatically as you type. Now, just press File - Export As - PDF, SVG or EMF.Just enter your text, your URL, a SMS or vCard contact information. When the result looks well, press the OK button to confirm the vectorization. You can also enable or disable Noise reduction (it is appropriate for natural photos). Set the Number of colors to tell Photopea, how many colors should the result have. When the vector result does not look perfect, you can improve it by changing settings. You can zoom in and out with a mouse wheel, and move the preview by dragging it (both previews are zoomed and moved simultaneously). Here, we can see two previews: the original raster image on the left side, and the new vector image on the right side. Press File - Open, and open your raster image.
Vectorization (or image tracing) can be done online for free. How can we do it faster? Converting Raster Graphics to Vectors Recreating such image by hand can take a lot of time. Often, we see images, that were originally made as vector graphics, but are only available as a PNG or JPG file.
