When to use this tool
Inspect a gzip payload transported as Base64. Recover the compressed bytes first, then decompress the gzip container locally.
Example
Use “Try example” to load this public sample and its settings, then run it.
Input

Result
Hello, world!
How the result is produced
Conventions and limitations
Gzip is not ZIP or zlib. Decompression can expand input substantially; use small trusted examples and respect the engine input/output limits. A failed decompression usually means the container type or bytes are wrong.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
