About 7Z to TAR conversion
7Z is a 7-Zip archive format introduced in 1999, using LZMA/LZMA2 compression algorithms. TAR is a Unix tape archive format introduced in 1979, which only handles packaging without compression. This conversion is designed to adapt to Unix system distribution and native archive workflows.
The conversion outputs an uncompressed TAR package, which will be larger than the original compressed 7Z file. It retains the directory structure and Unix file permissions from the original 7Z package, and the output TAR can be natively read and processed by all mainstream Unix-based systems.
This conversion is suitable for scenarios such as Linux software source code distribution and Unix system archive backup. If the total size after conversion exceeds 256MB or the number of files exceeds 1000, the service will reject processing and output.

FAQ about 7Z → TAR
Does file quality change after conversion?
Conversion only modifies the archive packaging, does not change the original content of files in the package, all data is fully retained with no quality loss. Decompression and repackaging are completed based on the 7-Zip engine.
Will original file permissions be retained?
Unix file permissions and symbolic link information from the original package are fully retained, which conforms to the TAR format specification and meets the usage requirements of Unix-based systems.
What is the single file size limit?
The single file upload limit is 50MB, only one file can be converted per request. Processing will be rejected if the total uncompressed size exceeds 256MB or the number of files exceeds 1000.
Will files be stored?
Files are uploaded to the server via HTTPS for conversion. After conversion is complete, the server immediately deletes both the source file and output file, no storage is performed.
