DEB to 7Z Converter
Processing entirely on your device — large files may take a moment.
7Z is ideal for big archives you store or share with power users; convert to ZIP when the recipient just needs to double-click. If your files are still in DEB format, this page is the shortcut: DEB is the Debian/Ubuntu package format: an ar archive whose members are control metadata plus data.tar.* holding the actual payload.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the DEB format
A .deb file is literally an ar archive (the Unix librarian format from 1971) containing three members: debian-binary, control.tar.* and data.tar.* — the last one holds every file the package installs. That transparency is why .deb extraction is the standard way to audit what a package will do to your system.
7-Zip parses the ar container and unpacks the inner tar automatically, so a browser can list and repackage the payload without ever touching a Linux shell.
+ Strengths
- ✓Transparent, auditable package structure
- ✓Standard across Debian, Ubuntu and derivatives
- ✓Inner tar is trivially repackaged
! Limitations
- −Meaningless outside dpkg-based systems
- −data.tar may use xz/zst compression variants
- −No cross-platform installer equivalent
About the 7Z format
7Z is the native format of Igor Pavlov's 7-Zip (1999), built around LZMA/LZMA2 compression — for years the ratio king against ZIP and RAR — with AES-256 encryption, solid archiving (similar files compress as one stream) and open, unpatented specifications. A 7Z of the same photos or code is routinely 20–40% smaller than its ZIP.
The trade-off is platform defaults: Windows Explorer and macOS Archive Utility do not open 7Z without third-party tools (7-Zip, PeaZip, Keka). It is the format for maximizing compression on your own terms, and for encrypted archives done properly (header encryption included).
+ Strengths
- ✓Top-tier compression ratio (LZMA2)
- ✓Real AES-256 encryption, optional header encryption
- ✓Open format, free tooling everywhere
! Limitations
- −No native OS support — recipients need tools
- −Solid mode makes single-file extraction costly
Why convert DEB to 7Z?
Converting makes sense where the strengths of 7Z meet what DEB cannot give you. Top-tier compression ratio (LZMA2) Meanwhile Meaningless outside dpkg-based systems One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this DEB to 7Z converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for DEB to 7Z?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are the files inside my DEB archive modified?
No. Contents are unpacked in memory and repacked into 7Z byte-for-byte — the conversion changes the container, never the files inside it.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the DEB file.
