Are private Pixelfed photos encrypted?

I just closed my Instagram account and was about to start uploading my photos to a private account on Pixelfed.
I was just wandering if the images I upload are stored encrypted or if everything is stored as is on the server.
I couldn’t see any mention of it, so I assume an instance owner could just go through everyone’s photos on the server even if they’re marked as private.
I tried looking through the source code to see if I could answer the question myself, but nothing is jumping out at me.
So hopefully someone with more knowledge than me can answer this question for me, thanks!

No, the server owner will absolutely see your photos if they want to.
The only way to do encryption you’re talking about is to defer the decryption function and keys to the front end so the backend never knows it. Meaning, you’d know it because every time you want to view the encrypted file you’d be prompted for that key (password) to continue.
That can be done transparently, just by using a key with no password (or using your account password for the key, so that when you log in it decrypts, and keeps the session open on your device).
The bigger problem is key management. You can’t allow the server to know your private key else the admin could steal it. So it has to stay on your device, and if you lose your device or accidentally delete the key, your account is gone.

Thanks for the response, that definitely clears things up!
Not necessarily. If you had a separate password to decrypt private images, you’d just have to enter it once at login or upon viewing the first private, encrypted photo.

I’m not sure PixelFed is the best choice for private storage of photos. It’s social media more than it is cloud storage.
Would Immich fit your requirements? I don’t think it encrypts either, but you can self-host it.
The best place to privately store anything is on your own machine, not anyone else’s.
I was more looking for social media rather than a private cloud image storage, I’ll probably still go ahead with using Pixelfed. I was just hoping it wouldn’t be possible for the host, to take everyone’s private photos and dump them online if they wanted to.
I guess Instagrams level of privacy would be similar and employees at Meta would be able to look at people’s private photos too.
Pixelfed isn’t private. Mastodon isn’t private. Lemmy isn’t private. All privacy is account privilege based.
The person who’s paying for the hard drive gets to see what’s on it.
If you are looking for open-source end to end encrypted photo storage then Ente or Stingle are what you want.
No ActivityPub-based services are really private. There is no mechanism for end-to-end encryption, access-listed posts, or even true DMs. ActivityPub is intended as a microblogging-style publishing service with interaction built in, with privacy not being in the spec’s scope.
Maybe some day they’ll retrofit privacy to the protocol, but that would involve reengineering it to handle key management and end-to-end encryption, which would be a hard problem.
No. As drspod said Immich is good. But you may want to check out Ente too. The servers/clients are open source and its encrypted. And for a free plan i’d say its quite good.
Personally use it, no qualms here.
PixelFed is not supposed to be for storing private photos. That’s what Immich/Ente are for.
and even then, only Ente does actual encryption on your photos.
Didn’t the Instagram admins do that too?
