How to encrypt files for cloud storage?

Question

Encryption

How to encrypt a folder with files so that an ordinary attacker who would somehow find out the password from the cloud (he picked it up, tortured me or he is a psychic) ​​could not open the pictures with my thick chin.

Will 7zip, WinRar encryption be enough, or will the drunk Uncle Vitya rewrite the photo code under Vodyaray into his native language "ablyuya Du" (to such an encoder the key will be the ratio of water and alcohol in his stack)?

Or advise some other suitable encoders, preferably with blackjack, back-scraping, and also with open source, well, you didn’t have to work all your life to work.

If just an archiver is enough for our MMXX year, then I'll sleep.
