About TAR
TAR (tape archive) bundles many files and folders into one file and keeps their Unix permissions, but it does not compress them.
Backups and software distribution on Linux and macOS, usually combined with gzip, bzip2 or xz.
A plain .tar file is about as large as the files inside, because no compression is applied.
Convert TAR to 7-Zip online free, no account required — 7-Zip is the archive format of 7-Zip.
Change TAR to 7-Zip without losing quality — convert TAR to 7-Zip free in your browser.
Why is my TAR file exactly the same size as its contents? TAR only bundles files together — it compresses nothing — so a 500 MB folder becomes a 500 MB archive until a compressor like gzip gets involved.
About 7-Zip
7z is the archive format of the free 7-Zip program. Its LZMA and LZMA2 compression usually packs files smaller than ZIP.
Distributing large software and data sets, and archives encrypted with AES-256.
macOS and older versions of Windows need extra software to open 7z files.
Why convert archives to 7Z? When size matters most: LZMA compresses noticeably tighter than ZIP, and 7-Zip itself is free.
