Decompressing an XZ archive extracts the underlying TAR file. Our browser-based tool allows you to perform this decompression locally in RAM without uploading your files to any server.
Decompressing XZ is fast because LZMA2 is optimized for reading, allowing rapid decompression in browser memory.

Native on Unix-like systems. Windows users can convert them to ZIP locally on our website.
No native encryption.
Yes, decompressing XZ extracts the uncompressed TAR file, which will be larger.
Yes, our tool decompresses the XZ layer and parses the TAR layout in a single step.
XZ compression speeds depend on the compression level and dictionary sizes used. Generally, XZ uses simpler dictionaries which makes it faster, while TAR focuses on achieving a tighter compression ratio at the cost of speed.
XZ is supported natively on most systems, while TAR files often require downloading separate utility apps or using web tools like iLoveExtract to open them.
Yes, both formats support file encryption. However, TAR typically supports AES-256 encryption, which is much stronger than older encryption algorithms sometimes found in XZ formats.
No, both formats use lossless compression algorithms. Converting between them extracts the files exactly as they are and packages them without losing any data.
XZ files have smaller header sizes, meaning they have less metadata overhead for single files. For large directory structures, TAR files organize headers more efficiently.
This depends on the formats. Many modern compression formats are open-source, whereas proprietary formats may require licensing or specific software binaries to write files.
The file size exceeds the supported safety limit.
