FORMAT

The suggested one for digital sharing would be JPG.

PNG is the best for images with complexity or transparency while PDF would work better for documents, emailing, and desktop printers. 

NOTE

It’s not possible to send a digital invite or RSVP for your guests to respond to their presence online.

We would recommend, including a QR code on your invitations, RSVP, or insert cards.
