ZIP to TAR

Repack a ZIP as an uncompressed .tar, the format most Unix tooling expects.

Bundling several files into one to send, opening an archive without installing anything, and cutting a file that exceeds an attachment or upload limit into pieces that can be put back together.

Treating the parts of a split file as files. A piece is a slice of bytes, not a smaller version of the original: it opens as nothing, and the whole is recoverable only if every part is present, unrenamed and in order. Losing one part loses the file.

They sit next to each other but answer different questions: TAR to ZIP is the one to open when you need it to repack a .tar, .tar.gz or .tgz archive as a ZIP that Windows opens without extra software. Pick whichever matches what you're starting from — both are free.

Create a TAR file is the closest one after this: Bundle several files into an uncompressed .tar, the archive Unix tooling expects.

Create a ZIP file and Extract a ZIP file — they come up in the same task often enough to be worth a second tab.

ZIP and TAR are open container formats with published layouts, and both are read and written here in the browser. A container records names, sizes and order; it does not record who made it or whether the contents are what they claim, so an archive is a wrapper, never a guarantee.
