Frequently asked questions

Does this TAR tool compress my files?

No. A TAR archive only bundles files together into one .tar without any compression, so the archive is roughly the same size as the combined files. To shrink it, compress the resulting .tar with a Gzip tool to produce a .tar.gz.

Are my files uploaded to a server?

No. The TAR archive is created and extracted entirely in your browser using JavaScript. Your files are processed locally on your device and nothing is ever uploaded, so your data stays completely private.

What kind of TAR archives can it open?

It reads standard uncompressed ustar TAR archives (.tar). For compressed .tar.gz or .tgz files, decompress them with a Gzip tool first, then extract the resulting .tar here.

Is there a file size or file count limit?

There is no fixed limit — you can add as many files as you like. Because everything runs in your browser, very large archives are constrained only by your device's available memory.

What happens to duplicate file names?

When creating an archive, only the base file name is stored, and duplicates are automatically renamed (for example file.txt and file (2).txt) so every entry in the .tar has a unique name.

Does it keep folders and subdirectories?

When creating a .tar, files are stored by their base name without folder paths. When extracting, regular files are recovered by their name; directory entries and other special types are skipped and only the actual files are pulled out.
