Até breve!

Use it exactly like you would use "see you soon" in English. It usually comes at the very end of an interaction. You can say it while waving goodbye or as the final line of an email. It is incredibly versatile and fits almost any social gear. It sounds polished but remains very friendly. Think of it as the 'Goldilocks' of Portuguese departures.

Use it when you have plans to meet someone later that week. It works perfectly at the end of a business meeting. It is great for ending a phone call with a friend. Use it when leaving a shop where you are a regular. It feels natural when you want to sound polite and educated. It’s the perfect exit line for a first date that went well.

Don't use it if you are never going to see the person again. That would feel a bit misleading or confusing. Avoid it in extremely high-stakes formal ceremonies where passar bem might be better. Don't use it if you are literally seeing them in five minutes. In that case, até já is the better choice. If you're angry and storming out, this phrase is far too pleasant!

Portuguese culture places a high value on social connection and politeness. Saying just tchau (bye) can sometimes feel a bit abrupt. Até breve adds a layer of warmth and expectation. It reflects the 'soft' nature of Portuguese social interactions. It’s a linguistic way of keeping the door open. It shows you value the time spent and look forward to the next time.

If you are seeing them very soon, use até já. If you have a specific time set, use até logo. For a more casual vibe with friends, try até mais. In Brazil, you might hear até a próxima quite often. If you want to be super casual, just a quick valeu, até works. Each one tweaks the timing just a little bit.
