PNG, JPG, SVG, and EPS formats are supported when downloading a QR code. You need to select one of the formats by clicking on the section next to the download button. Check out the link for details about supported file formats.
PNG: One of the most commonly used formats, it downloads high-quality QR codes. If the QR codes need to be printed in a fixed size without any changes, downloading in PNG format is ideal.
JPG: The JPG format is similar to PNG, but the difference is that files in JPG format are smaller than those in PNG. Because of this, the quality is somewhat lower.
SVG: SVG is in vector format, and therefore, files downloaded in SVG format are of very high quality. If the QR code's size needs to be frequently changed, SVG format is recommended during the download.
EPS: The EPS format is almost similar to SVG and vector format. If high-quality download is necessary, EPS format can be used. However, it's important to note that EPS is less well-known and is used by people.
