When it comes to Photo Storage, both iOS (iCloud) and Android (Google photos) make it easy. However, please do replace them! I back all mine up offline and have it on a USB, but that's me. So if you want a Photo Manager online, where you can share pictures with others or sync between your devices, we have a few good solutions for you.
Nextcloud is a fully open-source storage and productivity platform that keeps you in control. It's a monster when it comes to features, and you can seriously look to making it your full-blown Android/Google and desktop as well as iCloud replacement! It also lets you share links to photos or photo albums with family or external people with a specially generated link. Nextcloud is what I sometimes use, and it is an all-in-one solution!
Yes, like duck in German! This is a full-blown Google photos replacement. It is fully E2EE (end-to-end-encrypted). It lets you migrate iCloud, Google Photos, Amazon Photos and local files. The service is not free, but they do give you 1GB storage for 365 days for free.
Piwigo is open-source photo management software. Manage, organize and share your photos easily on the web. Designed for organizations, teams, and individuals.
PhotoPrism is an AI-powered app for browsing, organizing & sharing your photo collection.
It makes use of the latest technologies to tag and find pictures automatically without getting in your way. You can run it at home, on a private server, or in the cloud.
Cryptee's encrypted secure photo storage service is the best place to store your private photos. Your photos are encrypted before they leave your device, so they can’t see your photos, and no one else can either.
100 Mb are free so after that Cryptee will charge.
