Read guideOur editorial approach
PrivaFile guides focus on practical choices you can verify yourself. We explain what a format does well, where it can fail, and what to inspect after conversion. We do not claim that converting a file creates missing detail or improves a poor source. Your original should remain your master copy until you have opened and checked the result.
