Archive Converter
Upload your ZIP archive, then extract and repack every file into a downloadable TAR archive — free, private, and processed entirely in your browser.
About the Archive Converter
Our free online archive converter turns a ZIP archive into a standard, uncompressed TAR (ustar) archive. It's useful for system administrators, backup workflows, and Linux deployment pipelines that expect a tarball instead of a ZIP file.
Everything happens locally in your browser: the ZIP's Central Directory is parsed, every file is decompressed with the native DecompressionStream API, and a fresh set of 512-byte ustar headers is generated for the new TAR archive. Nothing is ever uploaded to a server, so your files stay completely private and secure.

Frequently Asked Questions
What is the difference between ZIP and TAR?
ZIP archives compress files to save space, while TAR files simply concatenate multiple files into a single archive without compression — making them ideal for preserving file metadata and permissions, and for tarball distribution on Unix and Linux systems.
Are my files uploaded to a server?
No. All extraction and re-packaging occur locally inside your web browser using the native DecompressionStream API — nothing ever leaves your device.
Why would I convert a ZIP to a TAR archive?
TAR is the standard archive format for Unix and Linux systems, used heavily for backups, software deployment, and container images. Converting a ZIP to TAR makes it easy to hand off files to a system administrator or a Linux-based workflow.
Does it cost money?
No. The archive converter is 100% free to use, with no registration or account required.
