7-Zip is a file archiver with a high compression ratio for ZIP and GZIP formats, which is between 2 to 10% better than its peers, depending on the exact data tested. And 7-Zip boosts its very own 7z archive format that also offers a significantly higher compression ratio than its peers—up to 40% higher! This is mainly because 7-Zip uses LZMA and LZMA2 compression, with strong compression settings and dictionary sizes, to slow but vastly improve density. If a zip tool gains its appeal from its ability to efficiently compress files, then 7-Zip proves it has a little bit o’ magic.

What's new in 7-Zip 24.08:
The bug in 7-Zip 24.00-24.07 was fixed: For creating a zip archive: 7-Zip could write extra zero bytes after the end of the archive, if a file included to archive cannot be compressed to a size smaller than original. The created zip archive is correct except for the useless zero bytes after the end of the archive.
When unpacking such a zip archive, 7-Zip displays a warning: "WARNING: There are data after the end of archive".
The bug was fixed: there was a leak of GDI objects (internal resources in Windows) in "Confirm File Replace" window, causing problems after 1600 displays of "Confirm File Replace" window from same running 7-Zip process.
Some optimizations for displaying file icons in 7-Zip File Manager and in "Confirm File Replace" window.
Some bugs were fixed.
