Learn French: Je mange tout ! - I eat everything!

Beaucoup de (a lot of) and un peu de (a little bit of) are used to describe the quantity of a specific noun (like a lot of apples). In this sentence, tout is used all by itself to mean the pronoun 'everything'. Because it stands alone and isn't describing a specific noun right after it, you don't need de.

So 'tout' means 'everything' here. Can it also mean 'all'?

Yes! When tout stands alone as the object of the sentence, like in this example, it means 'everything'. If you want to say 'all' or 'the whole' before a specific noun, you would add the article and noun after it, like Je mange tout le gâteau (I eat all the cake / the whole cake).

How is tout pronounced? Do I say the 't' at the end?

No, the final 't' in tout is completely silent. It is pronounced exactly like the English word 'too'.

If I wanted to say 'I do not eat everything,' where does tout go?

It stays at the end, after the negative parts! You would say Je ne mange pas tout. The negative ne ... pas wraps around the verb mange, and tout comes right after.
