Create a TAR.GZ archive

Package multiple files into a compressed TAR.GZ locally, with normalized filenames and round-trip verification.

Choose filesProcessed locally in your browser when supported.

Real TAR + GZIP

MakeFileWork first creates a POSIX ustar archive, compresses it with GZIP, then decompresses and reparses the result to verify the archive before download.

Safe limits

Up to 100 files, 60 MB total and 25 MB per file. Compression requires the browser's local CompressionStream support.
