Create TAR

TAR (tape archive) bundles many files into a single one without compressing them. It is the standard archive format on Linux and macOS and is often combined with gzip (.tar.gz). TAR keeps files unchanged - ideal as a container before compression.

This tool writes a USTAR archive (POSIX.1-1988) entirely locally in your browser (pure JavaScript). To shrink it as well, gzip the result afterwards into a .tar.gz. Nothing is uploaded.

The big advantage over simple gathering is that the order of your selection is preserved and files with the same name are automatically numbered (e.g. "image-2.jpg") instead of overwriting each other. Honestly framed: folder structures are not represented - every file lands as a single, flat entry in the archive; only the file name is kept, not a path. Because the format does no computing itself, writing is very fast.

Specifications

In 3 steps

1. Drop or pick your files.
2. The tool bundles everything into one TAR locally.
3. Download the TAR archive.

Limitations: TAR does not compress (same size as the sum of the files); gzip the TAR afterwards for a smaller archive. File names longer than 100 characters are not supported (the USTAR name field defined by POSIX.1-1988 is exactly 100 bytes long - a format limit, not a tool limit). Folder paths are not carried over - every file lands flat in the archive with just its file name.
