Turn TAR files into ZIP in a couple of clicks. TAR is an uncompressed Unix bundle — usually paired with gzip; ZIP is the universal compressed archive. Files are unpacked and repacked; their contents are unchanged.
Drop your files here
TAR files (.tar) · up to 500 MB each
or paste files from your clipboard
Ready when you are
Drop a TAR file above and FileTools360 will turn it into ZIP — right here on your device, without uploading anything.
Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.
The defaults suit most people. Open Advanced to control the output settings.
Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.
Privacy, in plain words
What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.
What happens instead. This site does not do it. There is no server here that receives files, so your TAR file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.
Check it yourself in ten seconds
Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.
The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.
An archive is a container, so its contents are whatever you were trying to keep together — which is usually everything above at once. It matters more than it sounds, because of what archives usually are:
Email exports
years of correspondence, including other people's
Photo libraries
thousands of images with their locations attached
Document bundles
legal or medical files collected for one matter
Source code
intellectual property, and occasionally hard-coded secrets
A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.
TAR bundles files without compressing them, preserving Unix permissions, ownership and symbolic links. It is almost always paired with a compressor, giving .tar.gz.
ZIP bundles multiple files into one and compresses them. Its indispensable property is that every operating system can open it with no extra software.
The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.
| Property | Source | Target |
|---|---|---|
| Compression | None | Lossless |
| Introduced | 1979 | 1989 |
| Browser support | Native on macOS and Linux; needs a tool on Windows. | Built into every operating system. |
People make this switch when they run into the limits of TAR: sending to Windows users. ZIP is the better fit when sending several files to someone whose setup you cannot control.
The content is not re-encoded — it is moved into a different container, so quality is unchanged and the conversion is quick regardless of file size. What may not survive is anything belonging to the TAR container rather than to the content itself, since ZIP does not necessarily have an equivalent.
Source
Uncompressed Unix bundle — usually paired with gzip.
Target
The universal compressed archive.
This is an unpack-and-repack, not a format conversion: the files inside are extracted and written into a new ZIP. File contents are byte-identical; Unix permissions and symlinks are not carried over.
