Is there an app I can self-host that will let users upload stuff to my server? I need something where I can send a link to someone, and they can upload files & folders to my server (it doesn't matter much to me where, as long as I can transfer them out to wherever I need later).

For example, I'm working to archive my parents' family photos which right now live on a bunch of external HDDs. I need a way for my (non-technical) father to be able to upload a folder with potentially 10k plus files to my server. Because of his poor internet reliability, and the potentially large size, I need something that has resumability (so that if it fails, it can pick up where it left off and not re-start from scratch)

Security-wise, it would be nice to be able to only have uploads work when I send a link. Other than that, I'm not worried about malicious uploads or anything.

Does anyone have any recommendations for this? (Or, if nothing exists, would folks find this useful? I might end up making it if I can't find it)
