Frequently asked questions
What is GZIP?
▾
GZIP is a file format and compression algorithm based on DEFLATE. It is widely used to compress HTTP responses, reducing transfer size by 60-80% for text-based content.
Why is the output base64?
▾
GZIP produces binary data. Base64 encoding converts it to a safe ASCII string that can be copied, stored, or sent over text-based channels.
Does compression happen on my device?
▾
Yes. This tool uses the browser's native CompressionStream API — no data is sent to any server.
