Q:Is KML to KMZ Converter free to use?
Yes, compressing KML to KMZ is fully free.
Q:Does KML to KMZ Converter upload my files to a server?
No, the compression process is local with no upload required.
Q:What file formats does KML to KMZ Converter support?
Supports KML files and converts them to KMZ (Zipped KML).
Q:Does it support external images?
Yes, you can include external markers and icons in the generated KMZ.
Q:What is the difference between KML and KMZ?
KML is a plain text XML format, while KMZ is a compressed ZIP archive that contains the KML file along with any referenced images and icons.
Q:Why should I convert KML to KMZ?
Converting to KMZ reduces file size significantly and bundles all custom icons and images into a single file, making it easier to share.
Q:How much smaller does the file get?
KMZ compression typically reduces KML file size by 70% to 90% depending on the geometry complexity.
Q:How much smaller will my KMZ file be?
Because KML is plain text (XML), it compresses extremely well. Expect 80-95% file size reduction. A 10MB KML typically becomes a 500KB-1MB KMZ.
Q:Is my data uploaded to your servers?
No. The entire KML-to-KMZ compression happens inside your web browser using JavaScript. Your files never leave your device.
Q:Why are my icons showing as red X marks in Google Earth?
This means Google Earth can't find the images referenced in your KML (e.g. local file paths like C:/photos/icon.png). When you convert to KMZ here, we bundle those image files inside the archive so they work on any device.
Q:What file size limits apply?
Individual KML files up to 100MB are supported. KMZ output size depends on how much the content compresses — pure text KML files compress dramatically, while KMZ files containing large images compress less.
