ZIP to TAR
Repacking a .zip archive as .tar moves the same files into a container with different compression and compatibility trade-offs. Free, private, and validated — the file never leaves your browser.

Repacking a .zip archive as .tar moves the same files into a container with different compression and compatibility trade-offs. A .zip file bundles files and folders into a single archive, compressing each entry individually. It is the only compression format that every major operating system can open and create without extra software, which is why .zip remains the default way to send multiple files.
A .tar file is a tape archive: many files and directories laid end to end in a single uncompressed stream, preserving Unix permissions, owners, and symlinks. It bundles but does not compress — that job is delegated to gzip, bzip2, or xz layered on top. For this route the practical draw is exact preservation of Unix metadata that other archive formats drop and dead-simple, fully streamable structure — balanced against uncompressed on its own, so bare .tar files are as large as their contents, which is worth knowing before you commit a large batch.
Why convert ZIP to TAR?
The practical trigger for this conversion is usually a mismatch: with .zip, weaker ratios than 7z or xz, especially across many small similar files. Switching to .tar buys you exact preservation of Unix metadata that other archive formats drop, which is why it is the better fit for source code distribution across the Unix world. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
ZIP vs TAR at a glance
| Aspect | ZIP archive (.zip) | TAR archive (.tar) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | every entry is compressed independently, usually with DEFLATE, so a single file can be extracted without touching the rest | each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries |
| Strongest at | emailing or sharing a batch of files as one attachment | source code distribution across the Unix world |
| Weak spot | weaker ratios than 7z or xz, especially across many small similar files | uncompressed on its own, so bare .tar files are as large as their contents |
| Metadata | stores modification times at DOS 2-second resolution and, through the Unix extra field, permission bits — though Windows-made ZIPs usually omit those bits, a classic cause of scripts arriving non-executable | records owner and group both by name and numeric id, permission bits, and modification times — extraction as root can restore ownership faithfully |
Pick TAR as the output
Select .tar in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TAR is selectable, the route is real and validated.
Convert on your device
Press Convert. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TAR file. Outputs keep the original filename with the .tar extension.
ZIP to TAR questions, answered
Will converting ZIP to TAR lose quality?
Since zip is container-oriented and tar is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .tar itself requires.
Is it private to convert ZIP files here?
Yes — the .zip file is processed inside your browser tab and never uploaded. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser. Close the tab and the file is gone from memory.
Where will the TAR file work?
Every Linux distribution, macOS, and the BSDs ship tar as a core utility, and Windows 10 and later include bsdtar at the command line. Graphical tools like 7-Zip open tarballs too, though they may need two passes for compressed variants.
Will the TAR file be bigger or smaller than my ZIP?
It depends on the content: each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my ZIP file?
In .zip, stores modification times at DOS 2-second resolution and, through the Unix extra field, permission bits — though Windows-made ZIPs usually omit those bits, a classic cause of scripts arriving non-executable. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert TAR back to ZIP?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .zip → .tar → .zip is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
