Add your XZ file
Drop one or more .xz files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Repacking a .xz archive as .zip moves the same files into a container with different compression and compatibility trade-offs. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Repacking a .xz archive as .zip moves the same files into a container with different compression and compatibility trade-offs. An .xz file holds a single stream compressed with LZMA2, delivering some of the best ratios of any general-purpose compressor. It follows the Unix one-stream philosophy — pair it with tar as .tar.xz when multiple files need archiving.
A .zip file bundles files and folders into a single archive, compressing each entry individually. It is the only compression format that every major operating system can open and create without extra software, which is why .zip remains the default way to send multiple files. For this route the practical draw is opens natively on Windows, macOS, Linux, iOS, and Android and random access: any single entry extracts without decompressing the archive — balanced against weaker ratios than 7z or xz, especially across many small similar files, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .xz, slow and memory-intensive to compress; huge dictionaries can strain small devices even on decompression. Switching to .zip buys you opens natively on Windows, macOS, Linux, iOS, and Android, which is why it is the better fit for emailing or sharing a batch of files as one attachment. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | XZ stream (.xz) | ZIP archive (.zip) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | lZMA2 chunks the LZMA stream so state can reset, enabling multithreaded compression and better error recovery | every entry is compressed independently, usually with DEFLATE, so a single file can be extracted without touching the rest |
| Strongest at | software release tarballs where download size matters most | emailing or sharing a batch of files as one attachment |
| Weak spot | slow and memory-intensive to compress; huge dictionaries can strain small devices even on decompression | weaker ratios than 7z or xz, especially across many small similar files |

Select .zip in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if ZIP is selectable, the route is real and validated.
Press Convert. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid ZIP file. Outputs keep the original filename with the .zip extension.
Since xz is container-oriented and zip is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .zip itself requires.
Yes — the .xz file is processed inside your browser tab and never uploaded. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser. Close the tab and the file is gone from memory.
File Explorer has handled ZIP since Windows XP, Finder and the GNOME/KDE file managers extract it with a double-click, and iOS and Android manage it through their Files apps. No mainstream platform requires any third-party install for basic ZIP work.
It depends on the content: every entry is compressed independently, usually with DEFLATE, so a single file can be extracted without touching the rest. Convert one representative file first and compare before batch-processing a large set.
