TAR vs ZIP — when to use which

TAR is the archive format Unix systems have used for decades: files are concatenated into one stream with 512-byte headers in the standard ustar layout, and the whole stream is optionally compressed with gzip. If your files are headed for a Linux server, a Docker build or a software release, .tar.gz is the conventional choice; for sharing with Windows users, ZIP opens more easily.

Unlike ZIP, where each file is compressed separately, a .tar.gz compresses the entire stream at once — which typically compresses many small similar files (like source code) better than ZIP does.

Private by design

Your files are processed directly in your browser using the browser's built-in APIs and are not uploaded to Filesvo. Nothing is stored on our servers, because nothing ever reaches them.

Frequently asked questions

What's the difference between .tar and .tar.gz?

A .tar is just the files joined together, uncompressed — useful when the contents are already compressed or when a build pipeline expects plain tar. A .tar.gz additionally compresses the whole archive with gzip, which is what you want for text, code and documents.

Is there a filename length limit?

Yes — the classic ustar header stores names up to 100 bytes. A file with a longer name is refused with a clear message asking you to shorten it, rather than silently truncating it.

Are file permissions preserved?

Browsers don't expose Unix permissions, so every file is stored with standard read-write permissions (644). Timestamps are set to the moment the archive is created.

Are my files uploaded to a server?

No. The archive is assembled and compressed entirely in your browser — your files never leave your device.
