## What compression does to TAR.GZ

Repacks at maximum gzip compression; the contents are byte-identical.

It's lossless, so there are no quality levels: every file comes back with identical contents, just packed more tightly.

Need it much smaller? xz typically compresses noticeably better than gzip. [Convert TAR.GZ to TAR.XZ](https://www.converterrr.com/tgz-to-txz).

## How to compress TAR.GZ

1. **Add your TAR.GZ files.** Drag and drop TAR.GZ files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Keep the default.** TAR.GZ compression is lossless, so there's nothing to tune: every file comes back with identical contents.
3. **Compress.** Click Compress. Files are processed in an isolated cloud sandbox and are usually ready in seconds.
4. **Download.** Download each smaller TAR.GZ, or everything at once as a ZIP.

## Good to know

- A TAR.GZ bundles files into one tar stream and gzips it. Repacking at maximum gzip effort makes it smaller with byte-identical contents.
- gzip is fast but not the strongest. For the smallest file, convert to TAR.XZ.
- Because TAR.GZ compression is lossless, it can't be aimed at an exact size: the result depends entirely on what's in the file.
- TAR.GZ files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## Compressing TAR.GZ: frequently asked questions

### How do I compress a TAR.GZ file?

Drop the TAR.GZ onto the compressor above, and click Compress. Download the smaller TAR.GZ when it's done; it usually takes a few seconds.

### Does compressing TAR.GZ reduce quality?

No. TAR.GZ compression is lossless. It repacks at maximum gzip compression; the contents are byte-identical.

### How much smaller will my TAR.GZ get?

Modest: maximum gzip effort squeezes out a few percent over the default settings.

### Can I compress TAR.GZ to a specific size?

No. Because TAR.GZ compression is lossless, the result depends on the content and can't be dialled to an exact number. If you need a much smaller file, converting TAR.GZ to TAR.XZ gets further.

### Is it safe to compress TAR.GZ files here?

Yes. Your file travels over an encrypted connection to an isolated sandbox created for your job only, and both the original and the result are deleted automatically.

### Is the TAR.GZ compressor free?

Yes. Cloud jobs like this one use the same free daily credits as cloud conversions, and there's no watermark.

### Should I convert my TAR.GZ instead?

Sometimes. xz typically compresses noticeably better than gzip. The TAR.GZ to TAR.XZ converter does that in one step.
