Upload your TAR.GZ archive file using the tool’s interface
-
Choose 7Z as the output archive format for conversion
-
Optionally select encryption and multi-volume archive settings if needed
-
Click the convert button to start compressing your TAR.GZ into 7Z
-
Download the new 7Z archive once the process completes
Key Features
-
Convert TAR.GZ archives using gzip compression into 7Z with LZMA/LZMA2 compression
-
Support for packaging multiple files and directories within a single archive
-
Option to create encrypted archives with AES-256 encryption for security
-
Ability to produce multi-volume (split) archives for easier transfer and storage
-

-
Open 7Z format compatibility with cross-platform 7-Zip implementations
Examples
-
Compress a software release tarball (TAR.GZ) into 7Z to reduce download size for your users
-
Convert nightly TAR.GZ backups to encrypted 7Z archives split into volumes for secure offsite storage
-
Repackage a directory collection from TAR.GZ to 7Z for improved compression and checksum verification
Common Use Cases
-
Minimizing file sizes when distributing software packages by converting from TAR.GZ to 7Z
-
Creating encrypted backups from existing TAR.GZ archives to protect sensitive data
-
Archiving large datasets with 7Z’s solid compression to save disk space
-
Preparing split 7Z archives for easier transfer across storage media or network systems
-
Improving long-term archive integrity with 7Z checksums and modern compression methods
Tips & Best Practices
-
Ensure your system has sufficient CPU and memory resources to handle 7Z compression and decompression
-
Use multi-volume archives for very large backups or transfers with size limitations
-
Leverage AES-256 encryption in 7Z for enhanced security when storing or sharing sensitive files
-
Verify extracted files to confirm successful conversion and integrity after compression
-
Consider the extraction overhead of solid compression when working with individual files inside 7Z archives
Limitations
-
TAR.GZ archives require full decompression to access individual files, impacting extraction during conversion
-
7Z solid compression can slow down extraction and modification of individual entries
-
Not all operating systems support 7Z archives natively; third-party software may be needed
-
7Z compression and encryption can be CPU- and memory-intensive on low-resource devices
Frequently Asked Questions
-
Why should I convert my TAR.GZ files to 7Z format?
-
Converting to 7Z can provide higher compression ratios, optional AES-256 encryption, multi-volume archive support, and better long-term storage capabilities compared to TAR.GZ's gzip compression.
-
Can I extract 7Z archives on any operating system?
-
Most operating systems require third-party tools like 7-Zip to extract 7Z archives, as native support is not universal.
-
Does converting TAR.GZ to 7Z affect file metadata?
-
Both formats preserve file metadata such as permissions and timestamps during conversion, ensuring data integrity.
Key Terminology
-
TAR.GZ
-
An archive format that combines multiple files and directories using TAR and compresses the resulting archive with gzip.
-
7Z
-
An open archive format using LZMA/LZMA2 compression, supporting features like AES-256 encryption and multi-volume archives.
-
Solid Compression
-
A compression method in 7Z that compresses similar files together to improve compression ratio but can increase extraction time.
-
AES-256 Encryption
-
A strong encryption standard used in 7Z archives to secure file contents and optionally headers.
