ZIP is usually the safest choice because it’s supported almost everywhere—Windows, Mac, Linux, and even mobile devices. 7Z offers better compression, but not everyone has the software to open it. TAR formats are great for Linux, but Windows users often struggle. If compatibility matters most, convert everything into ZIP.
Softaken Archive Converter makes this easy by converting TAR, 7Z, RAR, and others into ZIP without breaking the content. The process is fast, and files remain intact. For professional or personal sharing where recipients may not be tech-savvy, sticking with ZIP through a reliable converter is the smartest option.
