How to use this tool

1. Choose KML files.
2. Run compression and compare input and output bytes.
3. Download KMZ and open it in Google Earth or the KML viewer.

Limits and checks before sharing

Only the selected KML is packaged. Relative images, icons and models are not automatically collected; remote assets remain remote.
Already compact files may not shrink. Compression does not remove vertices or repair geometry.

If processing fails, check the file extension and source contents. Use a smaller batch if memory runs low. The original files are never overwritten. Inspect known locations and attributes before sharing a result.

Frequently asked questions

Does KMZ compression change my data?

The original KML bytes are stored as doc.kml in a ZIP archive. Coordinates and attributes are not converted or simplified.

Are linked icons included?

No. This tool does not fetch or bundle assets. Use your original asset-complete KMZ when icons or models must travel with the file.

Are my files uploaded, and do I need an account?

No. This file operation runs in your browser and needs no account or payment. The page and processing libraries need an initial network load. Opening a map preview can request external map tiles; linked resources in your original KML are not fetched or embedded by this tool.
