Archive Converter and Extractor - ZIP, 7z, RAR, TAR, GZ

How the Archive Converter Works

1. 01Drop an archive: ZIP, 7z, RAR, TAR, TAR.GZ or TGZ, or a single GZ, BZ2 or XZ file. The format is read from the bytes, not the name.
2. 02See every file inside with its size. Download one file, or all of them as a ZIP.
3. 03Convert the whole archive to ZIP, 7z, TAR or TAR.GZ with one click, or switch to Create to pack files you choose.
4. 04Everything runs in your browser. ZIP, TAR and GZ are handled natively; 7z, RAR, BZ2 and XZ load a 7-Zip engine compiled to WebAssembly the first time you need it.

ZIP, 7z, RAR, TAR and GZ: What the Differences Mean

ZIP compresses every file on its own and stores an index at the end, which is why any tool on any platform opens it and why it is the safe choice to send to someone else. 7z compresses files together with LZMA, so a folder of similar documents gets much smaller, at the cost of needing 7-Zip or a tool like this one. RAR is a proprietary format: it can be read here, but never written, which is also true of 7-Zip itself. TAR is not compression at all; it is a way to store a directory tree, permissions included, as one file, and TAR.GZ is that file compressed with gzip, the shape most Linux and macOS software ships in. A lone .gz, .bz2 or .xz is one compressed file with no directory inside. The converter reads any of these and writes ZIP, 7z, TAR or TAR.GZ.

When to Use This Tool

When someone sends a .7z or .rar and your machine only opens ZIP. When a download is a .tar.gz and Windows shows a file it cannot open. When you need to hand a folder to a client as a ZIP but keep your own 7z copy. When you want to look inside an archive before extracting it, or pull out one file without unpacking a thousand. And when you are on a tablet or a locked-down office machine with no archive tool installed.
