Compress a file to GZIP
Create a .gz file locally from one file.
Compression runs locally. GZIP handles one file and is not the same as ZIP, RAR or 7Z.
🔒 Your file is processed on your device and is not uploaded to our servers.
When to use it
Create a .gz copy of one file, such as text or a data export for a system that accepts GZIP.
What changes in the result?
GZIP handles one data stream, not a folder of files. It is not ZIP, RAR or 7Z. Already compressed files may not become smaller.
If conversion does not work
Use an updated browser. Corrupted GZIP files or output exceeding 64 MB are rejected to protect device memory.
