KMZ is simply a KML file (plus any referenced icons or overlays) compressed into a single ZIP archive with a .kmz extension. It's the format Google Earth produces when you save a place, because bundling everything into one compact file makes maps easy to email and share. Under the hood it's still KML, so a KMZ converts cleanly to and from every other geographic format.
Need the other direction instead? GeoJSONL is newline-delimited GeoJSON — one feature per line. GeoJSONL — also called newline-delimited GeoJSON, NDJSON or GeoJSON Text Sequence (RFC 8142) — writes one GeoJSON feature per line instead of wrapping everything in a single FeatureCollection. That streaming-friendly layout lets tools like Tippecanoe, BigQuery and DuckDB read enormous datasets line by line without loading the whole file into memory. It's the format of choice for large-scale geospatial pipelines.

KMZ to GeoJSONL — FAQ
- How do I convert KMZ to GeoJSONL?
- Upload your .kmz file using the converter above (drag & drop or click to browse). GeoMaps converts it to GeoJSONL instantly in your browser and gives you a .geojsonl file to download. No software to install and no signup required.
- Is the KMZ to GeoJSONL converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert GeoJSONL back to KMZ?
- Yes. Use our GeoJSONL to KMZ converter for the reverse conversion — every format on GeoMaps converts both ways.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
