What is GZIP compression?

GZIP is a file compression format that uses the DEFLATE algorithm. It is widely used for compressing single files and is the standard for HTTP content encoding on the web.

GZIP vs ZIP — what is the difference?

GZIP compresses a single file into a .gz archive, while ZIP can compress multiple files into one archive. GZIP generally achieves better compression ratios for single files.

How much compression can I expect?

Text files typically compress by 60-80%. Already-compressed files (images, videos) see little additional reduction.

Is this GZIP compressor free?

Yes, completely free with no limits. Compress as many files as you need, no registration required.
