I had the .tif file and by using "Layer to kml" toolbox (without changing the preset parameters) i got the kmz file with very bad resolution. Then i tried to modify it changing the values for output image properties. But the results is strange, instead of having the same cell size i got this weird shifted/overlapped pixels. Scale and all other parameters stayed the same, only the output image properties that were changed..

Have you ever met this problem?

this is the original tif file converted into kmz

Yes this does happen, unfortunately... you can try to minimize the change of cell values by;

  1. Project your original raster layer to WGS84 beforehand. (At least this gives you a chance to choose interpolation method fit for your purpose). Do not leave projection process to this tool.
  2. Layer To KML has Output Image Properties. This allows you to specify the Size of returned image (pixels). Use a multiple of your raster size (columns or rows).
  3. Setting higher DPI may also help (i have not tried).

Still, we cannot have much hope for a perfect translation to KML.
