A .gz file is a single file compressed with gzip \u2014 commonly a server log, SQL database dump, JSON export, or CSV snapshot \u2014 and the fastest way to open one is to drop it onto the EasyExtract GZ extractor<\/a>, which decompresses it in your browser with nothing to install.<\/strong> Most people land here because they received a .gz from a server, a colleague, or an automated backup and don’t have a decompression tool ready. This guide covers the browser method and the native OS commands.<\/p>\n

What is a .gz file?<\/h2>\n

Gzip compresses one file at a time. That is the key difference from ZIP<\/a>, which can bundle many files into one archive. A .gz file almost always holds a single file, and the original name is usually baked into the gzip header:<\/p>\n\n\n\n\n\n\n\n\n
.gz filename<\/th>\nWhat’s inside<\/th>\n<\/tr>\n<\/thead>\n
access.log.gz<\/td>\naccess.log<\/td>\n<\/tr>\n
database.sql.gz<\/td>\ndatabase.sql<\/td>\n<\/tr>\n
data.json.gz<\/td>\ndata.json<\/td>\n<\/tr>\n
export.csv.gz<\/td>\nexport.csv<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Important:<\/strong> a .tar.gz (or .tgz) is a different format. It first bundles multiple files into a tar archive, then gzip compresses that bundle. If your file ends in .tar.gz or .tgz, use the TAR extractor<\/a> instead \u2014 it handles both steps.<\/p>\n

How to open a .gz file online (step by step)<\/h2>\n

No install required. The decompression runs entirely in your browser using the browser’s built-in support \u2014 your file never leaves your device.<\/p>\n

    \n
  1. Go to the EasyExtract GZ extractor<\/a>.<\/li>\n
  2. Drop your .gz file onto the page, or click to browse and select it.<\/li>\n
  3. The file is decompressed instantly in your browser.<\/li>\n
  4. The original filename is shown \u2014 recovered from the gzip header when present.<\/li>\n
  5. Click Save file<\/strong> to download the decompressed result.<\/li>\n<\/ol>\n

    There is no size limit imposed by the tool itself; the practical ceiling is your device’s available memory.<\/p>\n

    How to open a .gz file on Windows, Mac, and Linux<\/h2>\n

    If you prefer a desktop method, each platform has a built-in or readily available option.<\/p>\n

    Windows<\/h3>\n

    Windows 11 (build 22000 and later) can open .gz files natively via File Explorer \u2014 right-click the file and choose Extract All<\/strong>. On Windows 10 or earlier, download 7-Zip<\/a> (free), right-click the .gz file, and choose 7-Zip > Extract Here<\/strong>.<\/p>\n

    Mac<\/h3>\n

    Double-click the .gz file in Finder. Archive Utility handles gzip natively and places the decompressed file in the same folder. From Terminal:<\/p>\n

    gunzip filename.gz<\/code><\/pre>\n
    Linux<\/h3>\n
    Run either of these in the terminal:<\/p>\n
    gunzip filename.gz\n# or\ngzip -d filename.gz<\/code><\/pre>\n
    Both produce the original file in the current directory and remove the .gz.<\/p>\n
    What about .tar.gz files?<\/h2>\n
    A .tar.gz (also written .tgz) is not a simple gzip file. The tar utility first bundles a directory or multiple files into a single .tar archive; gzip then compresses that bundle. The GZ extractor will detect this situation and tell you \u2014 but to list and extract the individual files inside, use the TAR extractor<\/a>, which handles the combined tar + gzip format in one step.<\/p>\n

    Frequently asked questions<\/h2>\n
    \nHow do I open a .gz file?<\/summary>\n
    Drop it onto the EasyExtract GZ extractor \u2014 your browser decompresses it instantly and you save the original file. No software needed. Alternatively, on Mac double-click it in Finder; on Linux run gunzip filename.gz<\/code> in the terminal; on Windows use 7-Zip.<\/p>\n<\/details>\n
    \nWhat is inside a .gz file?<\/summary>\n
    A .gz file holds a single compressed file \u2014 usually a log, a SQL dump, a JSON or CSV export. The original filename is stored in the gzip header when it was created. A .tar.gz is different: it bundles multiple files with tar first, then compresses with gzip.<\/p>\n<\/details>\n
    \nCan I open a .gz file without WinRAR or 7-Zip?<\/summary>\n
    Yes. Use the EasyExtract GZ extractor in your browser \u2014 it decompresses the file using the browser’s own built-in support and saves the result. Nothing is installed and nothing is uploaded.<\/p>\n<\/details>\n
    \nWhat is the difference between .gz and .tar.gz?<\/summary>\n
    A .gz file compresses one file. A .tar.gz (also called .tgz) first bundles multiple files into a tar archive, then compresses that bundle with gzip. Use a TAR extractor for .tar.gz files.<\/p>\n<\/details>\n<\/section>\n
