Select all the parts of a split file — .001, .002, .003 — and drop them together. They're rejoined in order and the archive is extracted, all in your browser.
archive.zip.001, archive.zip.002, and so on — and drop them on the box above..zip, .7z, and more), it's extracted automatically and you can download the contents.When a file is too big to email or upload, tools like 7-Zip, WinRAR and split chop it into equal pieces named .001, .002, .003. Each piece is just a raw slice of the original bytes — none of them opens on its own. To use the file you glue the slices back together in order, and this page does exactly that, then hands the result to the extractor.
Joining large multi-gigabyte parts by uploading them to a website is slow and exposes your data. Here the parts are read and concatenated in your browser with WebAssembly — nothing is sent anywhere. Open the network tab and watch: no request carries your file data.
Multi-volume RAR sets — .part1.rar / .part2.rar or the older .r00 / .r01 — are not plain byte splits, so they can't be joined by simple concatenation. This tool covers numeric splits like .001 / .002, including split .zip and .7z. For a single-volume .rar, use the RAR extractor.
Yes — every part from .001 through the last, with no gaps. A missing piece leaves a hole in the joined file and it won't open. If a part didn't finish downloading, grab it again before joining.
