How do I convert a 7Z file to COMPRESS format?

Upload the 7Z file to the converter. Choose COMPRESS as the output format. Click 'Convert'. Our tool extracts the entire 7Z contents, compresses each file using LZW (the Unix compress algorithm), and bundles them into a .Z archive. Download the resulting COMPRESS file instantly.

Why should I convert 7Z to COMPRESS instead of keeping 7Z?

7Z uses the LZMA/LZMA2 algorithm for high compression ratios, while COMPRESS uses LZW, which is older and less efficient. Converting to COMPRESS is essential for compatibility with legacy Unix tools like 'uncompress', older mail servers, or embedded systems that only accept .Z files. The trade-off is a larger file size, but you gain universal support in environments that lack 7-Zip.

What data attributes are preserved during 7Z to COMPRESS conversion?

When converting 7Z to COMPRESS, the raw bytes of each file are preserved exactly, but metadata such as Unix file permissions, ownership, and extended attributes from the 7Z archive are lost because the COMPRESS format only stores a compressed stream without a file container. If the 7Z contains multiple files, we flatten them into individual .Z files or package them into a TAR archive first to maintain the directory tree.

Is 7Z-TO-COMPRESS free to use?

Yes, 7Z-TO-COMPRESS on LetsConvert is 100% free with no registration or hidden fees required.

Is there any software installation required?
