Compress any file using gzip compression online for free. Reduce file size for faster downloads, email attachments, and storage. No signup, no downloads and completely free.
Optimizing your file. This may take a moment.
Select any file you want to compress. Our tool supports all file types including documents, images, archives, and more.
We apply gzip compression using maximum compression level (level 9) to reduce your file size as much as possible.
Download your compressed .gz file immediately. The compressed file can be decompressed using standard gzip tools.
Smaller files download faster, saving time and bandwidth.
Compressed files fit within email size limits more easily.
Save storage space in cloud drives and backup systems.
Gzip is widely used for web server compression and optimization.
Gzip provides lossless compression, preserving all file data.
Gzip is supported by all major operating systems and tools.
Yes, our gzip file compressor is completely free to use. There are no hidden charges, premium features, or limitations on the number of compressions.
You can compress any file type using gzip compression. This includes documents, images, archives, videos, executables, and any other file format. Gzip works best with text-based files but can compress any binary data.
To decompress a .gz file, you can use standard gzip tools. On Windows, use 7-Zip or WinRAR. On Mac and Linux, use the built-in `gunzip` command or double-click the file. Most archive tools support gzip decompression.
Compression ratios vary depending on your file content. Text files and code files often compress by 70-90%. Binary files like images or videos that are already compressed may see smaller reductions (0-30%). Uncompressed data typically compresses the best.
Yes, all file processing happens securely on our servers. Files are processed immediately and are not stored permanently. We prioritize your privacy and security.
Currently, the tool processes one file at a time. If you need to compress multiple files, you can create an archive (like a .zip or .tar file) first, then compress that archive with gzip.
We use gzip compression level 9, which is the maximum compression level. This provides the best compression ratio but may take slightly longer to process very large files.
No, gzip is a lossless compression algorithm. Your original file data is preserved perfectly. When you decompress the .gz file, you get back the exact original file with no data loss.
