Can't comment on the nebulous "safe" but it works over the interweb, you join a "private room" using the buttons in the top-right and the devices should just see each other. You can also pair devices so they permanently see each other. I sometimes have to close and reopen on one device or the other for the devices to find each other.

Good point about the word "safe." A better way to phrase my question is, for sharing low sensitivity SFW photos w/ friends and/or family (e.g., a group photo at a bar or restaurant, or a family photo from Christmas morning), would you trust a tool like PairDrop or Destiny over "traditional" sharing methods such as texting the photo to everybody over SMS? (assuming we aren't or can't get on the same network, otherwise I'd probably just go w/ LocalSend)

I mean, it uses WebRTC which is an encrypted format, I suppose if you have to go via a relay server that might be a possible attack vector but certainly not enough to worry about over something like a group photo.

For multi-recipient or if you're worried about snooping you might want to try https://wormhole.app/ instead, which is instead a temporary file host, it'll host files for 24 hours encrypted at rest (the encryption key is built into the URL you share)

Thanks for the tip about the Wormhole app. It looks like PairDrop also supports multi-recipient based on a brief visit to their website and cursory review of their FAQ (that is assuming multiple recipients can join a room). Still good to know about various alternatives, though, especially for asynchronous transfers.
