From your PDF menu you can create easily a QR code that your customers will scan to consult your menu online.

In the 'Apps' section of your account, install the 'Le Menu' application.
Upload your PDF menu with a name and a language (multi-lingual).
You can import several documents.
A QR-code is automatically generated for each document.
You can save the QR code image (right click in your browser then Save the image) and use it to deploy your QR code on your tables, table stands, and pinboards.
By scanning your QR code, you reach your online PDF menu at a custom address similar to: https://leme.nu/X/X

For an interactive menu (order from table side) you will need to configure the digital menu with the online store. More information.

You will find a lot of online services to create your menu in PDF (ex: Canvas)
