How to Convert an Archive to ZIP

  1. Drop your archive - RAR, 7z, TAR, tar.gz, tar.bz2, and tar.xz are all accepted.
  2. Wait a moment - The archive engine loads on first use, then the contents are read on your device.
  3. Download the ZIP - Every file and folder is repacked into a standard ZIP with the structure preserved.

The Extract tab opens any of the same formats and lets you download files individually, and the Create tab bundles loose files into a fresh ZIP.

Why Convert to ZIP at All

Because ZIP is the only archive format everything opens. Windows, macOS, iPhone, Android, and every corporate system unpack ZIPs natively, while a RAR sent to the wrong person generates a "how do I open this" reply, and 7z is a developer format most people have never installed software for. Converting is the polite move before sharing: whoever receives the ZIP just double-clicks it. The trade is honest to know about: RAR and 7z typically compress harder than ZIP, so the converted file often grows a little. You are trading a few percent of size for universal compatibility, which is nearly always the right trade at sharing time.

An Archive Tool With No Server Behind It

Online archive converters normally receive your file, process it on a server, and hand back a link, which means your documents sit on someone else's machine at least briefly. This tool skips that model: the same libarchive engine that powers desktop archive software runs here as WebAssembly inside your browser tab, and JSZip rebuilds the output locally. For anything sensitive, financial records, ID scans, client work, that difference is the whole point. If the archive also needs a password, our Password Protected ZIP tool adds AES encryption, likewise without anything leaving your device.

Frequently Asked Questions

Do my files touch a server when converting or extracting? They do not. Reading RAR, 7z, and TAR archives is done by libarchive compiled to WebAssembly running in your browser, and the new ZIP is assembled there too. Files are read into memory on your device, repacked, and saved straight back, with no upload step anywhere in the pipeline.
Which formats can I convert to ZIP? RAR (including RAR5), 7z, TAR, and compressed TAR variants like tar.gz, tar.bz2, and tar.xz. The output is always a standard ZIP that opens natively on Windows, Mac, iPhone, and Android with no extra software.
Can it handle password-protected archives? Not currently. If an archive is encrypted, the tool detects it and tells you rather than producing a broken ZIP. For creating an encrypted archive of your own, our Password Protected ZIP tool does AES encryption in the browser.
Why does the first conversion take a moment to start? The archive engine is a one megabyte WebAssembly module that only loads when you first open a RAR, 7z, or TAR, keeping the page fast for people who just need plain ZIP work. After that first load it stays ready for the rest of your visit.
Is there a size limit? Your device's memory is the ceiling, since the archive is unpacked and the ZIP rebuilt in RAM. A few hundred megabytes is comfortable on a typical computer. Solid-compressed 7z and RAR archives take the longest, because the format requires decompressing in sequence.
Why is my ZIP barely smaller, or even bigger, than the RAR? RAR and 7z usually compress harder than ZIP, so converting trades some size for compatibility; a modest growth is normal and expected. And if the archive contains photos, video, or MP3s, no archive format shrinks them much, since those files are already compressed internally.
Can I just pull one file out instead of converting? Yes. The Extract tab lists everything inside the archive with individual download buttons, so you can take exactly what you need. It reads all the same formats the converter does.
