Decompress the GZIP stream and package those bytes inside a ZIP as content. GZIP represents one stream rather than a directory tree, so this route does not infer the original filename or unpack a nested archive. The dedicated archive inspector provides a different workflow for examining and selecting archive members.

## Useful tasks

- Prepare a ZIP container for an app that does not accept GZ.
- Create a fresh archive copy while keeping the original untouched.
- Move regular file contents through a bounded local archive workflow.

## Steps

1. **Select your GZ files**: Use Select File or drop supported GZ files into the upload area. Each file creates a separate ZIP result. Check that the filename extension matches the contents and that the original opens correctly before adding a larger batch.
2. **Review the format notes**: This GZ to ZIP operation uses fixed settings. Read the output notes before proceeding, especially if document layout, table structure or archive contents matter. The available operation is based on the installed local engine, not a change to the filename alone.
3. **Convert to ZIP**: Select Convert to add the files to the local queue. Files run one at a time, with real progress where the engine provides it. You can cancel a queued or running job and retry a failed result after correcting its input or settings.
4. **Download and check the result**: Selections and completed jobs stay available while you navigate inside this tab. Use My files to revisit results. Reloading or closing the tab clears the workspace; download results you want to keep first.

## Settings


## Confirm the container and its contents

Start with an archive containing notes.txt and an images folder. Convert it, then open the new ZIP container with an archive reader and compare the member names and file contents. TAR output is uncompressed; another container is not guaranteed to make the same files smaller.

## Check the result

Check the member list after repacking. Unsafe paths, duplicate names, links, special entries, corrupt checksums and expansion beyond the supported budget cause a failure rather than a partial successful download.

## About GZ

Compresses a single stream of data using GZIP. Converting a ZIP to GZIP compresses the archive itself without extracting its contents.

## About ZIP

Packages files in a widely supported archive. Local tools check file paths and enforce expansion limits.

## Limits

- Files are processed on this device. Browser memory and engine-specific limits apply. Save results before reloading.
- ZIP to GZIP compresses the ZIP container, without extracting files.
- GZIP to ZIP stores its decompressed bytes as content.
- Archive expansion capped at 100 MB and 1,000 entries; unsafe paths are rejected.
- Processing runs in this browser. Large files may exceed your device memory; save results before reloading.
- Up to 20 files per session, 100 MB per file and 200 MB per output. Processing has a 180-second job deadline.

## Questions

### How do I convert GZ to ZIP?

Choose your GZ files, review the format notes, then select Convert. Download the finished ZIP copy and check it in your destination application. Each input is processed independently; the original file remains unchanged.

### Are all archive features preserved?

Archive conversions depend on the selected formats. Review the format limits for handling of folders, timestamps, permissions and compressed contents.

### Which settings can I change for GZ to ZIP?

This route uses fixed conversion settings. There are no hidden quality or layout controls. Read the format limitations above, or choose a dedicated tool from the related links if you need a different kind of processing.

### Will the result be smaller or better quality?

A successful ZIP conversion does not guarantee a smaller file or recovered detail. Container overhead, compression and the selected settings all affect output size. Check the saved result and keep the source if you might need a different export.

### Why did my GZ file fail?

Read the message beside the file. A mismatched extension, corrupt data, unsupported feature or resource limit can prevent conversion. Check that the source opens normally, try the default settings and retry. The app will not offer a successful download for a failed job.

### Where are files processed and how long are they kept?

Processing runs in this browser, on your device. Files and pasted input are not uploaded to a conversion server. The website and required engine assets must load first; large operations depend on available device memory.
