GZIP is a file archiving and compression tool associated with the .gz filename extension. The utility was first released in 1992 for the UNIX operating system, with the intention of replacing the 'compress' tool that comes bundled with UNIX. Today (2015) the tool exists as a standalone cross platform file archiver. Several archiving and compression utilities exist that support the .gz (otherwise known as gzip) format. The motivation behind the format and utility was to create a capable compression archiving tool that was unencumbered by patents of other compression algorithms that existed at the time, particularly those surrounding the LZW algorithm.
The .ZIP file extension format is a file archive and data compression format originally developed and released in 1989 by Phil Katz. With compatible zip format software, a file or a group of files can be packed (compressed) into a single .zip archive which can later be unpacked (decompressed). The zip file archive format facilitates the distribution of multiple files as single archives particularly over the internet and networked systems. Many operating systems have native support for the file format and can usually open zip archives without the need for third party software. Microsoft windows for instance has had native support for the ZIP format since Microsoft Windows 98, similarly Apple's Mac OS includes ZIP support through its default archive file handle Archive Utility.
FreeFileConvert uses tuned encoding for GZIP to ZIP conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload GZIP files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized ZIP 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 ZIP audio with dependable progress tracking.
The format requires that a gzip compatible compressor correctly set identification blocks (ID1, ID2), the compression method, the CRC-32 algorithm to verify the integrity of the archived file, and ISIZE ' the size of the original input. The possible values for compression method is 0 to 7 with 8 reserved for the DEFLATE algorithm which is typically the default method associated with the gzip format.
Many other common filename extensions use the ZIP format in one aspect or another, for example JAR, .WAR, .DOCX, .XLXS, .PPTX, .ODT, .ODS, .ODP all utilize the ZIP format. The ZIP format provides for data integrity through the CRC32 specification with support for digital signatures. It also supports multiple compression algorithms but commonly utilizes the DEFLATE algorithm.
Upload your archive file in the GZIP format from your device, Dropbox, or Google Drive.
Select ZIP 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.
