ZIP converter

ZIP is the archive everyone can open, which makes it the natural landing place for the formats that not everyone can. The tools below run completely inside your browser: archives are unpacked and repacked on your own machine, so the contents are never uploaded to a server they had no business visiting.

What is ZIP?

ZIP is the archive format the whole computing world agreed on: a 1989 design that bundles files and folders into one compressed container using DEFLATE. Windows, macOS, Linux, phones and even email clients open ZIPs natively, with no extra software. It is not the strongest compressor available, but its universality made it the default way to hand someone a folder, attach multiple files or download a project.

Common questions about ZIP

What is a ZIP file and why convert other archives to it?
ZIP is the most widely supported archive format: every operating system can open one with no extra software, and most apps that accept an archive expect ZIP. That makes it the natural target when you receive a TAR, TGZ, or 7z archive that the person or tool on the other end cannot open. hushvert repacks those archives into a plain ZIP so the contents stay the same but the wrapper is universally readable.
How do I create a ZIP on hushvert, and does my file upload?
You convert TO ZIP from a TAR, TGZ, or 7z archive, and the whole repack runs client-side in your browser using WebAssembly. The archive is never uploaded. hushvert reads the source archive in the browser, then writes a new ZIP from its contents locally. You can confirm nothing leaves your device by watching the Network tab, or by trying it in airplane mode on our /privacy-proof page.
Can I convert a ZIP into another format on hushvert?
No. ZIP is a destination here, not a source. hushvert repacks TAR, TGZ, and 7z archives INTO ZIP, but it does not convert a ZIP back out to TAR, TGZ, or 7z. If you already have a ZIP, it is already in the format almost everything can open, so there is usually nothing to convert.
Does converting to ZIP change my files or compress them differently?
The files inside are preserved exactly: hushvert reads each entry from the source archive and writes it into the ZIP unchanged. The compression wrapper does change, since ZIP uses its own DEFLATE compression rather than gzip or 7z's LZMA, so the resulting ZIP may be a slightly different size than the original archive. The actual file contents and their folder paths are identical.
Is there a limit on how many files I can put into a ZIP?
Because the repack runs entirely in your browser, the practical limit is your device's memory rather than an account quota. Client-side conversions on hushvert are free and unlimited with no sign-up. Very large archives with thousands of entries will use more RAM during the repack, so on a low-memory device a huge source archive may be slow.
