Best File Compression Format to Use in 2026 | I Tested 52 Formats to Find the Winner

Which file compression format is actually the best in 2026? We took one identical 55MB mixed-media folder and fed it into 52 different compression formats — from 1985's vintage ARC to the absolute cutting edge of 2026 — and measured every single result. Here's what we found.

It opens everywhere and nobody has to install a thing. • Documents & text → 7-Zip. Noticeably smaller, and it only costs you a second or two. • Photos & video → ZIP them to bundle and organize, but don't expect them to shrink. • Long-term archiving → stick with an open format like ZIP. The fancy stuff may not open in twenty years. Need to zip or unzip something right now?
