About GZIP Compression
GZIP is one of the most widely used compression formats, powering web compression (HTTP Content-Encoding), log file compression, and software distribution. It uses the DEFLATE algorithm for efficient single-file compression.

Frequently Asked Questions
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.
Create a ZIP archive
Bundle files without changing their contents. JPEG, MP4 and other compressed files may shrink very little in a ZIP.
There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing. Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size. The tool can reduce image detail; its target size is not guaranteed. If forms, signatures or searchable text matter, keep the original PDF.
