No. Everything runs in your browser - your file never leaves your device. How this is verifiable
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 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.

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 (plain USTAR format). Folder paths are not carried over - every file lands flat in the archive with just its file name.
No. The TAR is built entirely locally in the browser.
TAR only bundles, it does not compress. Gzip the TAR for a .tar.gz.
With our "Extract TAR" tool or any archive program.
No. Every file is stored flat with its file name, without directory structure; identical names are numbered automatically.
The widely supported USTAR format, which every common tool reads.
