Tar File Creator

Bundle files into a TAR archive (optionally gzip-compressed as .tar.gz), or open an existing .tar, .tar.gz or .tgz and download the files inside — all in your browser, with no upload.

How to use it

Create a TAR

1. Set Mode to Create a TAR archive.
2. Drop up to 50 files into the upload area, or click to browse.
3. Name the archive and choose a Format: plain .tar or gzip-compressed .tar.gz.
4. Press Create TAR and download the result.

Extract a TAR

1. Set Mode to Extract files from a TAR.
2. Drop in a .tar, .tar.gz or .tgz file.
3. Press Extract Files and download each file, or all of them re-bundled as a ZIP.

Settings

• Archive Name — the downloaded filename; the right extension is added automatically.
• Format — .tar stores files uncompressed (fastest, and the right choice for already-compressed files); .tar.gz runs the whole archive through gzip for a smaller download.

How it works

Files are read with the File API and packed into POSIX ustar records (512-byte headers and padded data blocks). Long paths use the ustar prefix field or a GNU long-name record, so deep folder names survive. Gzip is applied with a JavaScript implementation, and extraction detects gzip by its header bytes rather than the filename. Directory entries, symlinks and special files are skipped; only regular files are listed.

Privacy

Everything runs entirely in your browser. Your files are never uploaded to a server.
