What is the difference between GZIP and ZIP?

GZIP compresses a single stream of data using the DEFLATE algorithm, while ZIP is a container format that can hold multiple compressed files. GZIP is commonly used for compressing web responses and single-file data streams. ZIP is used for bundling multiple files into a single archive.

What input format does the decompress mode accept?

The decompress mode accepts Base64-encoded GZIP data, which is the most common way GZIP data is represented in text form. You can also paste raw GZIP data in hex format. The tool automatically detects the input format and decodes accordingly.

Is my data sent to a server during compression or decompression?

No, all processing happens entirely in your browser using the Compression Streams API. Your data is never transmitted to any server. This ensures complete privacy, making the tool safe for compressing sensitive data like API keys or confidential text.

How much compression can I expect with GZIP?

GZIP compression ratios vary depending on the content. Plain text typically compresses 60-80%, JSON and XML compress 70-90%, while already-compressed data like images sees minimal reduction. The tool displays the compression ratio so you can see exactly how much space you save.

Can I compress binary files with this tool?

This tool is primarily designed for text-based compression. For binary files, you can use the Base64 representation of the file as input. For full binary file compression, our Create ZIP tool may be more appropriate.

What browsers support the Compression Streams API?

The Compression Streams API is supported in all modern browsers including Chrome 80+, Firefox 113+, Safari 16.4+, and Edge 80+. If your browser doesn't support it, the tool will display a compatibility notice. Most users on current browsers will have full support.

Can I use the compressed output in my code?

Yes, the Base64-encoded GZIP output can be used directly in your code. When decompressing, you can use the same Base64 string. This is useful for embedding compressed data in web applications or APIs that need to transfer compressed payloads.
