Gzip Compressor is a gzip helper for API debugging, everything is computed locally in your browser, so your input never reaches a server.

Paste or type your content and press the button; results can be copied in one click.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

How do I use the output?+

The result is Base64 text for easy copy and paste. Decode it to a .gz file if you need the binary.

Why does decompression fail?+

Make sure you pasted complete gzip data in Base64 form; plain text cannot be decompressed.

Is Gzip Compressor free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does Gzip Compressor work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
