The .gz filename extension refers to the GZIP file format and compression/decompression utility of the same name which was initially released in 1992. It is the extension given to files compressed using the gzip utility. Unlike other compression tools of the time, gzip was originally intended to be used as a tool to compress a single file as opposed to multiple files or entire directories compressed as a single archive. As a work around, multiple files can be archived using the TAR archive file format, then that single TAR archive would then be compressed using the GZIP format. This would give the file a filename extension of .tar.gz.
.bz2 is the filename extension associated with the bzip2 data compression format. It is an open source data compression and decompression tool developed by Julian Seward in 1996. The compression and decompression format is cross platform compatible and comes bundled with versions of Linux and UNIX. The latest of Bzip2 exists as an open source library for download and customization. Earlier versions have executables that can be run directly on Microsoft Windows.
FreeFileConvert uses tuned encoding for TGZ to TBZ2 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload TGZ files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized TBZ2 results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent TBZ2 audio with dependable progress tracking.
The GZIP format uses the DEFLATE algorithm for compression. A file in this format consists of a 10 byte header containing the version number, timestamp, and magic number. Other blocks include optional extra header blocks, the DEFLATE payload, and a CRC-32 checksum contained in an 8 byte footer.
Bzip2 compresses data using the Burrows-Wheeler block-sorting text compression algorithm, and Huffman coding. It is a client of the libbzip2 library. Because the bzip2 is built on top of this freely available library, users are free to create their own programs to compress and decompress bzip2 files.
Upload your archive file in the TGZ format from your device, Dropbox, or Google Drive.
Select TBZ2 as the output format and click Convert. Adjust optional settings if needed.
Download the converted archive file. Each file stays available for up to 5 downloads.
