    First you'll need to make sure you have a dependency on gt-image and gt-geotiff:


    Then you can simply open the JPG with WLD file (or any other image based file) and write it out as a GeoTIFF.

    AbstractGridFormat format = GridFormatFinder.findFormat(input);
    Hints hints = null;
    if (format instanceof GeoTiffFormat) {
      hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE);
    AbstractGridCoverage2DReader reader = format.getReader(input, hints);
    GridCoverage2D grid =;
    File out = new File("test.tif");
    GeoTiffFormat outFormat = new GeoTiffFormat();
    GridCoverageWriter writer = outFormat.getWriter(out, hints);
    writer.write(grid, null);
