dropbox alternative (cloud storage)

[bluesmap]

I have tried a basic search and am unable to find what i'm looking for or the results are years old.

I am looking for an alternative to dropbox. I hear dropbox is not as secure as i might think. I want a free cloud storage alternative where i can secure my files and access them from another computer at work or when im away via browser (similar to dropbox)
I only need about 100mb storage or even less i dont need much space, i have mostly pdf files and doc files that i need access to.

i was looking at Tresorit and also SpiderOak but neither of those are free

I use a free email acct.; protonmail which gives me 500mb of storage. This includes my actual mail. Protonmail is also fully encrypted with 2factor.
