GIS

KML → GPX

Easily convert KML geographic files to GPX format for use in handheld GPS devices and outdoor navigation apps. This tool is essential for travelers, hikers, and GIS specialists.

KML (Keyhole Markup Language) is developed by Google and commonly used in Google Earth for displaying geographic data with custom styling and polygons. GPX (GPS Exchange Format) is an XML schema designed specifically for GPS data, focusing on waypoints, tracks, and routes for navigation hardware. Converting KML to GPX extracts the geographical coordinates and paths from Google Earth structures and adapts them into a lightweight, standardized format readable by Garmin, Wahoo, and hiking apps.

Core waypoints and track coordinates are preserved accurately, though complex KML styling, 3D extrusions, and polygon fills may be omitted since GPX focuses strictly on linear paths and points.

Tips

Simplify overly complex KML polygons into track points before converting for better device compatibility.
Check your KML file for multiple layers and export only the active track or route you need.
Ensure your KML coordinates use standard WGS84 latitude and longitude to prevent offset issues on your GPS device.

Common use cases

Transferring a custom hiking route planned in Google Earth to a Garmin GPS watch.
Converting tourist sightseeing markers from a KML map into a GPX file for offline mobile navigation.
Preparing drone flight paths or field survey tracks for upload to dedicated outdoor navigation hardware.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🗺️

GIS & maps

Geographic and spatial data layers.

Common extensions: GeoJSON, KML, SHP, GPX, GPKG

Advantages

+ GeoJSON is native to web maps
+ KML works with Google Earth
+ Shapefiles are common in GIS workflows

Disadvantages

− SHP needs multiple sidecar files
− Coordinate systems must match the target
− Large datasets need simplification

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

Frequently asked questions

No, GPX format does not support advanced KML styling, icons, or custom colors. The conversion focuses entirely on geographical coordinates, routes, and waypoints.

GPX format primarily handles tracks and routes rather than filled polygons. Closed boundaries in KML will typically be converted into outline track lines.

The converted GPX file is compatible with almost all outdoor GPS units like Garmin and Magellan, as well as mobile apps like Gaia GPS, OsmAnd, and Wikiloc.
