no, the chances of a hash collision from different files is so small as to be practically zero the hash does not reveal anything unless you know where to find it and the short codes you already use are way more likely to have a collision than a full 32 byte, 64 character hexadecimal (or shorter bech32) - now, those hashes, yes, they can collide much more easily, but even still they are at least 48 bits by my estimation which is far far less than a full 32 byte, 256 bit hash
