Technical note

KML to JP2: what to expect from the conversion

KML coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. JP2 is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the KML original if anything downstream needs to query or reproject the features. KML describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JP2 afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as JP2 opens on any computer and any phone. reaConverter produces those from KML in batch, entirely offline.

  • Render every file in a folder to JP2 with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

KML to JP2 Conversion

What are KML files?

The KML format uses a variant of the XML language, called Keyhole Markup Language, to manage geospatial data. It is used for rendering detailed maps by browsing applications such as Google Earth. The KLM format supports various handy features, including placemarks, paths and ground overlays, and can be edited with any text editor.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
