Create a TAR archive
Add one or more files and bundle them into a single uncompressed .tar archive. Everything runs in your browser. Your files never leave your device.
About .tar archives
A .tar (tape archive) writes a small 512-byte header before each file and pads each entry to a 512-byte boundary, then ends with two empty blocks. This tool writes the POSIX ustar variant, which every modern tar reader understands. Because .tar applies no compression, the archive is about the size of your files plus that header overhead — it bundles, it does not shrink. For a compressed bundle, use Create ZIP or Gzip.
Is it private?
Yes. The archive is built by JavaScript running on your own machine. Nothing is uploaded, stored, or seen by us. There is no server to send files to.
Frequently asked questions
- What is a .tar file?
- A .tar archive bundles many files into one, preserving their names. It is the classic Unix way to package a set of files together. Unlike a .zip, a plain .tar applies no compression — it simply concatenates the files behind small headers.
- Will the .tar be smaller than my files?
- No. A .tar bundles files without compressing them, so the archive is roughly the sum of your files plus a little header overhead — it can be slightly larger, never smaller. If you want a smaller file, use Create ZIP or Gzip instead.
- Are my files uploaded to a server?
- No. The archive is built by JavaScript running on your own machine. Nothing is uploaded, stored, or seen by us, because there is no server to send files to.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Add your files, create the .tar, and download it.
