In order to offer your users an optimal experience with a PDF QR code, we recommend keeping the file size of the PDF file to a minimum.
Optimizing your PDF files will lead to a faster download time, and you will use less webspace of your account.
Big PDF files lead into long loading times
In many cases, the images embedded on a PDF file, have a very high resolution and produce PDF files with a big file size.
Viewing a PDF on a Smartphones requires less resolution
When you connect a QR Code to a PDF file, your customer will be visualizing the PDF document on a smartphone in 99% of the cases. Therefore, there is no need for high resolution images, because the display is quite small in comparison to desktop computers.
