File Splitter

Cut any large file into pieces — of a fixed size, or into a number of equal parts — then download them together and rejoin them later.

Bundling several files into one to send, opening a ZIP or a TAR 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. Create a TAR file: bundle several files into an uncompressed .tar, the archive Unix tooling expects. Pick whichever matches what you're starting from — both are free.

Create a ZIP file is the closest one after this: Bundle several files into one ZIP, choosing how hard to compress them.

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 the container is a wrapper, never a guarantee. The parts a splitter writes record nothing at all: they carry no header, and a merger restores the original only if every piece is present and in order.
