ZIP protects file contents with AES-256 but keeps filenames visible.

Compress files into a new archive

An archive groups many files into one downloadable package while preserving their names and folder paths. Choose ZIP for broad compatibility, 7Z when compact storage matters, or a TAR-based format for common Unix and backup workflows.

TAR is an archive container rather than a compression method, so a plain .tar file may be larger than its inputs after headers are added. TAR.GZ wraps the TAR data in GZIP compression, which can reduce the final size when the source content is compressible.

How to compress files online

  1. Select individual files or choose a folder, then review the paths that will be stored in the archive.
  2. Choose ZIP, 7Z, TAR, or TAR.GZ, enter an archive name, and optionally add a password for ZIP or 7Z.
  3. Click Compress Files, wait for the archive to be prepared, and download the result.

Online archive compressor FAQ

Which archive format should I choose?

ZIP is the most broadly compatible general-purpose choice for sharing across phones and computers. 7Z often produces a smaller archive but may require a compatible extraction app. TAR preserves a directory tree without compression, while TAR.GZ adds GZIP compression to a TAR archive.

Can I compress an entire folder?

Yes. Use Select Folder to keep relative folder paths in the archive. Folder selection depends on browser support, so selecting the files directly remains available as an alternative.

Are my files uploaded?

Your files are handled in the browser and are not uploaded by this tool. You should still avoid leaving sensitive results in a shared computer's downloads folder.

Why can a very large archive fail?

Archive work uses your device's memory and processing power. Very large selections can exceed the practical limit of a browser tab, so splitting a large job into smaller archives may work better.

Can I create a password-protected archive?

Yes, for ZIP and 7Z. ZIP uses AES-256 to protect file contents, although filenames remain visible. 7Z protects the contents and hides filenames. TAR and TAR.GZ do not support passwords.
