How to download QR codes into different file formats

The technical factors to keep in mind when designing should be thoroughly checked, as scanning QR Codes from bad graphics can lead to lost customers and failed marketing campaigns. Therefore, you should clearly define the requirements, such as the required file size and type in advance.

What are QR codes, and how do they work?

QR Code, also known as Quick Response Code, QR Code was developed to improve the information capacity and efficiency of the Barcode. They use a square shape that allows them to be read both horizontally and vertically, instead of just horizontally like Barcodes. Due to their unique 2D technology, QR Codes can hold hundreds of times more information than Barcodes and are 7 to 30% more error-tolerant.

Make sure your QR Code design is readable.

QR codes are scalable for different media, but they should generally have an absolute minimum size of 2 x 2 cm (about 0.8 x 0.8 in). They need to be large enough for the QR code scanner to read, have the right colours, have good enough image quality not to be blurry, and stand out enough for the reader to notice them.


How to download QR Codes to different file formats


QR Gateway software allows you to generate QR Codes in four different image file formats. But before we get to the file formats, here is a quick guide on downloading QR Code designs using QR Gateway.


How to download QR codes on QR Gateway


Once you've signed in to your QR Gateway account and completed your QR Code design, you'll need to print it so QR Code can add it to whatever media you plan to use. You will then see your QR Code image on the left with a large "DOWNLOAD" button. This button is viewable regardless of whether your custom tab is selected.





You can click "DOWNLOAD" at this stage, and your QR Code will automatically be downloaded as a PNG file. Or, you can open a QR code editor and click the three dots to the right of the "save" button for additional file format options.



The QR code can then be downloaded as a PNG, JPG, SVG, or EPS file.

The following describes the different image file formats for QR Codes and when you may need them.

What is an SVG file?

How it works: SVG stands for scalable vector graphics. Vector graphics are an image file format that, as opposed to JPEG, is not made up of pixels. Instead, it uses paths; specific shapes used to create an image. They work well for both simple drawings and complex diagrams. SVG is thus a 2D version of vector graphics that depicts text in a text format and is the standard file format for using vector graphics in digital media. See here for a list of all the programs that read SVG files.


When to use: SVG files are helpful when you need to scale your QR Code to a large size. As mentioned above, vector graphics do not use pixels like other images. The problem with pixel-based photos is that their quality will decrease if you increase their size. Because of this path structure, SVG files don't have this problem. Therefore, they are ideal for larger web-based images, icons, illustrations, and QR Codes.


What is an EPS file?

How it works: EPS stands for Encapsulated Postscript and is another type of vector graphics. They are considered the top quality choice for high resolution printed graphics. EPS files are easily scalable and can be opened with specific graphic design programs like Adobe, like other vector graphics.


When to use: If you plan to use your QR Code on printed materials or printed advertising, an EPS file might be your best bet. Since EPS files use vector graphics paths, they would be ideal for QR Codes for billboard advertisements or posters so that the quality is evident even when viewed from a distance. Note, however, that the EPS file is black and white only, which means that any custom features added to your QR Code using the QR Gateway software will not display in this format. If you want to add custom features to your QR Code separately, an EPS file might be the right choice for you.


What is a JPG file?

How it works: JPG stands for Joint Photographic Experts Group and is the most common image file type. A typical JPG image uses a 10:1 compression ratio, which means if you create a 10MB image and export it as a JPG, it will result in 1MB. JPG files compress images by grouping pixels together to appear similar to the pixels around them.


When to use: While JPGs are the standard for photography, the problem with them is that the image quality degrades each time they are saved. This makes them unsuitable for detailed graphics and illustrations with sharp lines. For QR Codes, it's best to start with a different type of file format and then export to JPG later if you need a smaller file size.



What is a PNG file?

How it works: PNG stands for Portable Network Graphic and is a file that uses compression to match bits of data from an image with shortcodes stored in the file itself. This makes it a smaller file but still high quality. PNG has "lossless compression", meaning that the quality is not lost every time the image is opened and saved. They also handle colour contrast well for colour-rich images.


When to use: Because they manage image compression, PNG files are often the default for screenshots. They produce near-perfect pixel representations instead of squeezing groups of pixels together like JPGs. Although they are larger files than JPGs, PNG files work well for web graphics. So when you use this file type for your QR Code, it will be more suitable to put on your website or social media posts.


The information in the two-dimensional code corresponds to the resources on the Internet, and the information capacity of the two-dimensional code is infinitely amplified through the Internet.
