About the ZIP to GZ Converter
This ZIP to GZ converter turns archives from ZIP into GZ without installing software or uploading anything. It solves a common problem: Linux servers, packages and scripts often expect TAR or GZ archives. Converting to GZ gives you a gzip-compressed file, ideal for compressing single files, logs and database dumps on Linux servers.
Archives are unpacked and repacked with fflate, a fast open-source compression library, entirely in your browser. Because everything happens on your own device, your archives are never uploaded, stored or seen by anyone else, which makes it safe for backups, source code and confidential files.
What to expect: file names and folders are preserved; encrypted (password-protected) archives cannot be opened.
How to use the ZIP to GZ Converter
- Click "Choose files" or drag your ZIP archives onto the box. You can add several at once.
- Choose the compression level if the output is compressed.
- Press "Convert to GZ". The conversion runs on your device and shows its progress.
- Download each GZ file, or use "Download all (ZIP)" when you converted several.
- Open the result in Linux and macOS (gzip/gunzip) or 7-Zip to check it; your original ZIP is never changed.
Tips & benchmarks
- A single file becomes file.gz; several files are bundled with tar first, giving a .tar.gz.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the GZ to a website or government portal.

Gzip was written in 1992 as a free replacement for the Unix compress program. It compresses a single file, which is why several files are first bundled with tar to create a .tar.gz.
