How it works
- Drop a .gz file or paste text
Log files, exports, API responses saved via curl — all common in the wild.
- Pick the direction
Decompress .gz to see its contents, or compress text/files into a .gz.
- Download or copy
The decompressed content lands as a file, ready for a text editor.
Questions people actually ask
Is .gz the same as .zip?
No — gzip compresses one stream, no file names, no archive. .zip bundles several files. The tools here each do what their format does.
A .tgz file — can this open it?
Not here; .tgz is gzip wrapped around a tar archive, and needs archive handling first. If it matters, say so via the contact page.
