At what resolution are the photos stored?

The photos are stored in the highest resolution available and you can retrieve them in the same quality at no extra cost.

Most social networks and especially WhatsApp apply compression algorithms with loss of quality to reduce the size of the images they share. For this reason, it is recommended that your guests do not add images to your rolls that have been received through these applications, because you would be collecting files with low resolution. It is best that your guests add the photos taken directly from their own devices, and thus you will get the photos with the highest resolution.

Having the maximum resolution in your photographs is ideal for any type of printing or even to have room to rectify the photo frame.
