About TGZ to 7Z conversion
TGZ is the GNU TAR gzip compressed packaging format launched in 1992, and is the standard format for Linux source code and deployment packages. 7Z is the 7-Zip archive format launched in 1999, which uses LZMA/LZMA2 compression algorithms. Users typically convert to this format to get a higher compression ratio.
This conversion is processed based on the 7-Zip engine, and preserves the complete directory structure and file permissions from the original archive. 7Z usually has a better compression ratio than the original TGZ format, and can use solid compression blocks to reduce output file size. The output supports cross-platform decompression.
This conversion is suitable for archiving Linux source packages on Windows devices, and adapts to compression management workflows that depend on the 7Z format. Processing is subject to security limits: total uncompressed size may not exceed 256MB, and there may be at most 1000 files.

FAQ about TGZ → 7Z
Does file quality change after conversion?
Conversion is lossless and does not alter the content of original files. The archive is only repackaged and recompressed, so no quality loss occurs to any files inside the archive, and original files can be fully restored.
Will the original directory structure be preserved?
The directory structure and file permissions from the original archive are fully preserved. The converted 7Z file can fully restore all content, and complies with the reading rules of most 7Z decompression software.
What is the maximum single file size limit?
The maximum size for a single file is 50MB, and only one file can be converted per operation. In addition, the total uncompressed size may not exceed 256MB, and the total number of files may not exceed 1000. Processing will be rejected if these limits are exceeded.
Do you store my uploaded files?
Files are uploaded to the server via HTTPS for conversion. After conversion completes, the server immediately deletes both the source file and the output file, and does not store any files. Your privacy will not be compromised.
