Does TAR Creator upload my files to any server?
No. TAR Creator runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.
TAR Creator
Create a tar archive in your browser from up to 500 files. Names that escape the archive are refused, never silently re-rooted.
Choose files
Choose files to pack into a .tar archive.
Entries are written with the names you see.
Archive
The .tar archive appears here.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
How to use it
- Choose up to 500 files.
- Check the list of names that will go into the archive.
- Create the tar archive and download it.
Limits worth knowing
- Files are stored uncompressed; combine with GZIP Compressor for .tar.gz.
- ustar limits apply: 100-byte names, 155-byte prefixes; longer ones are refused with a clear message.
- 500 files / 512 MB total per archive.
- Each entry is written with 0644 mode and zero timestamp metadata.
Why tar is not a “big ZIP”
tar stores files sequentially with a small header and no compression or random access. It exists for Unix pipelines, where “read this archive” and “prepare another thing” are one motion. That makes it excellent for manual backups and extremely boring for distribution — which is why archives of archives, tar inside gzip, exist.
Paths are the security-critical part: a tar file is a list of names that somebody’s tool will later honour. This tool refuses any name that could walk out of the extraction root before it is ever written.
Size limits and determinism
The output is deterministic: same files, same bytes, every time — useful when you want a reproducible archive for diffs and signatures. Timestamps are zero by design, so tar differences reflect only content.
Frequently asked questions
Is TAR Creator free to use?
Yes, TAR Creator is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.
What file formats and sizes are supported?
TAR Creator supports * files up to 512MB directly in your browser.
What does the tar file contain?
A standard ustar archive: one header block per file, files stored uncompressed, and two zero blocks at the end. GNU tar, bsdtar and every Linux reads it.
Are folder paths preserved?
Only the file names you see are stored; this tool does not silently invent directory entries. If you need the folder hierarchy inside the archive, TAR Extract below and repack with paths in mind.
Which names are refused?
Absolute paths, drive letters, any .. segment, and control characters — refused before a header is written, never rewritten behind your back.
Is my file uploaded?
No. The archive is assembled in this tab and offered as a download; nothing leaves your device.
