![]() This is because MP4 itself includes data compression, in this case optimized for compressing audio and video data without significantly lowering the perceived quality. Your results will vary widely depending on the exact specifics of the MP4 encoding used. Now, with that out of the way, let's move on to your main question: Some formats, such as ZIP, 7z, or RAR, combine archiving and compression (although ZIP can store files uncompressed as well). Some of them (such as Gzip and LZ4) may support compressing multiple files and concatenating them into one file that can then be uncompressed into the multiple original files (which is what's happening when you gzip a directory), but they don't' store paths or other metadata, so they are not archive formats. Gzip, Bzip2, Brotli, LZ4, LZOP, XZ, PAQ, and Zstandard are all compression formats. Tar is an example of a pure archive format, it does no inherent compression,Ī compresion format just compresses data, but does not inherently combine multiple files into one. To be a bit more specific:Īn archive format aggregates multiple files and/or directories, usually including metadata such as ownership, timestamps, and possibly other data, into a single file. Gzip and Bzip2 are compression formats, not archive formats. ![]() First, a minor aside about terminology: ZIP is the only archive format you used.
