Why convert TAR to 7Z?
TAR and 7Z handle compression differently — check the comparison below before you convert anything you can't re-export from the original. The main reason to convert TAR to 7Z is compatibility: 7Z extracts with the archive tool already built into your OS, while TAR doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, 7Z is usually the safer target.
Format comparison
| TAR | 7Z | |
|---|---|---|
| Extension | .tar | .7z |
| MIME type | application/x-tar | application/x-7z-compressed |
| Compression | no compression scheme of its own | lossless compression |
| Category | archive | archive |
Your file, handled carefully
Uploads are encrypted in transit and at rest, processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
Frequently asked questions
Is converting TAR to 7Z free?
Yes — the first 50 conversions every month are free on any plan, including TAR to 7Z.
Will I lose quality converting TAR to 7Z?
7Z is open archive format with very high compression ratios. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
No, not by default. You choose a retention window at upload — immediate, 1 hour, 24 hours or 7 days — and the file is permanently deleted after that.
What is TAR?
Unix tape-archive container, usually paired with gzip.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click, and nothing is charged against your quota for a failed job.
