You can put bread in the fridge but actually refrigerating bread makes the bread go stale and bad quicker than it does just leaving it out.
When bread is put in the fridge the bread in the refrigerator will dry out and become stale much faster than it would when it was just left out.
Bread is best stored at room temperature in a dark place such as in a bread box or in a dark pantry.
It's best to eat the bread before it has time to go bad and get more fresh bread instead of keeping bread too long.
Bread isn't very good for long term storage but you can extend the shelf life of bread by freezing the bread but if you do freeze the bread it won't be a s good tasting and may become soggy once it thaws out.
