About Converting KMZ to KML

KMZ is simply a KML file zipped together with any images, icons or overlays it references. It is the format Google Earth exports by default because it keeps a whole annotated map in one portable file. When you need to move away from KMZ, the usual reason is simple: must be unzipped before the geometry can be edited as text.

Converting your KMZ map file to KML solves that. KML is the XML format Google Earth introduced for describing points, paths, polygons and overlays on a map. It became an Open Geospatial Consortium standard in 2008 and is now read by most mapping software. In practice you gain native to google earth and google maps and carries styling, labels and descriptions alongside geometry. PrivConvert runs the whole KMZ-to-KML conversion in server memory and deletes your file the instant the KML is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need native to Google Earth and Google Maps
  • You need carries styling, labels and descriptions alongside geometry
  • You need plain XML, so readable and editable by hand
  • Sharing a KMZ map file with someone whose software expects KML

Tips for best results

  • After converting, open the KML and skim the formatting — complex layouts occasionally need a small touch-up.
  • Files up to 250 MB are supported, and you can batch-convert several KMZ files at once; each is processed privately and deleted immediately.

Why convert KMZ to KML with PrivConvert?

PrivConvert turns your KMZ into KML without ever storing, logging or sharing it. Here is what that looks like in practice:

Fast in-memory processing

Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.

Nothing is stored

We never keep a copy. Once your KML is delivered, both the original and the result are gone — there is nothing left to leak or misuse.

Isolated sandbox

Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.

No human ever sees it

Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.

Frequently Asked Questions

What is a KMZ file?
A KMZ is simply a ZIP archive that bundles a KML document together with its icons and overlays. This tool pulls out the main KML (doc.kml) so you get an editable, plain-text file.
Are styles and folders preserved?
Yes. The KML is returned exactly as it was stored inside the archive, so placemarks, folders, styles and overlay references are all kept intact.
Is it safe?
Yes. The archive is opened in memory with zip-bomb size limits, and the KML is validated with an XXE-safe XML parser that refuses DTDs and external entities. Nothing is written to disk and the file is deleted immediately after conversion.
