Reminds me I had been needing to find something for this too. Looks like I had thought about using Croc.

I've use Plik before with success.

Just share the folder on soulseek. Probably not advisable for any sensitive information though xD

Wormhole.app, can't recall if they have a limit atm

You can OnionShare if you're worried about privacy.

i like zipline but i use it for smaller files where download resumability is not a key factor

rsync

Not sure if this works for you but I didnt see it mentioned. I use plex for my media server, so I would just put whatever it is on there and then someone else can log in remotely and download it through the app on their mobile, and I think also via the website too.

I know this works if the person is downloading from android but haven't tested otherwise.

Upload to Proton Drive > Create share link > Share link

I use an ancient HTTP File Server program called HFS from Rejetto. Very light weight. Supports making user accounts and whatnot if you want.

I usually just turn it on for a transfer and don't leave it up these days, but still comes in handy on occasion.

I use https://www.sendbig.com/ I haven’t read their privacy policy, though.

I host pingvin for people to send stuff to me. To send, usually I'll just move the file into a folder that exposed to Nginx with indexing and send that link. Otherwise I'll also just use my pingvin instance.

I tell them to start their Nextcloud client. Or if they don't have it, give them the share link.
