Produces better compression ratios than the DEFLATE compression algorithm (used by .zip and gzip/.gz) and does so faster.
By separating the jobs of archiving (.tar), compressing (.zst), and (if you so choose) encrypting (.gpg), .tar.zst follows the Unix philosophy of "Make each program do one thing well.".
.tar.xz is also very good and seems more popular (probably since it was released 6 years earlier in 2009), but, when tuned to it's maximum compression level, .tar.zst can achieve a compression ratio pretty close to LZMA (used by .tar.xz and .7z) and do it faster^1.
zstd and xz trade blows in their compression ratio. Recompressing all packages to zstd with our options yields a total ~0.8% increase in package size on all of our packages combined, but the decompression time for all packages saw a ~1300% speedup.
Can handle lossy images, lossless images, images with transparency, images with layers, and animated images, giving it the potential of being a universal image format.
Much better quality and compression efficiency than current lossy and lossless image formats (.jpeg, .png, .gif).
Produces much smaller files for lossless images than AVIF^2
Supports much larger resolutions than AVIF's 9-megapixel limit (important for lossless images).
Supports up to 24-bit color depth, much more than AVIF's 12-bit color depth limit (which, to be fair, is probably good enough).
it’s already a NATO standard for documents
Because the Microsoft Word ones (.doc, .docx) are unusable outside the Microsoft Office ecosystem. I feel outraged every time I need to edit .docx file because it breaks the layout easily. And some older .doc files cannot even work with Microsoft Word.
This is the kind of thing i think about all the time so i have a few.
