Convert TGZ to IGZ

Understanding tgz and igz file formats

TGZ is a compressed archive file format that combines TAR (Tape Archive) and GZIP compression. It is commonly used on Unix and Linux systems to bundle multiple files and directories into a single compressed file, typically with the .tgz or .tar.gz extension.

IGZ is a much less common file extension. In most cases, .igz is simply a GZIP-compressed file with a non-standard extension, sometimes used for specific applications or systems. There is no widely recognized or standardized IGZ format, so it is generally treated as a GZIP file.

How to convert tgz to igz

Since both TGZ and IGZ are based on GZIP compression, converting a .tgz file to .igz usually involves renaming the file extension. However, if you need to extract the contents of the .tgz archive and then compress a specific file into .igz, follow these steps:

1. Extract the .tgz file using an archive manager or command-line tool.
2. Compress the desired file(s) using GZIP, specifying the .igz extension.

Best software for tgz to igz conversion

• 7-Zip (Windows): Extract .tgz files and compress files using GZIP. After compression, rename the output file to .igz.
• WinRAR (Windows): Supports extraction of .tgz files and GZIP compression. Rename the resulting .gz file to .igz.
• GNU tar and gzip (Linux/macOS): Use the terminal to extract and compress files. Example commands:
  tar -xzf archive.tgz
  gzip -c file.txt > file.igz

Step-by-step conversion using 7-Zip

1. Open 7-Zip and navigate to your .tgz file.
2. Right-click the file and select Extract Here to unpack the archive.
3. Select the file you want to compress, right-click, and choose 7-Zip → Add to archive....
4. Set the archive format to gzip and specify the output file name with the .igz extension.
5. Click OK to create your .igz file.

Conclusion

Converting .tgz to .igz is straightforward since both formats use GZIP compression. The process typically involves extracting the .tgz archive and recompressing the desired file(s) as .igz. 7-Zip and GNU tar/gzip are the best tools for this conversion.
