gis - How to avoid compression when converting GeoTIFF to MBTiles?

Question

I have been trying to convert a set of GeoTIFF files into MBTiles using gdal_translate (GDAL 3.0.4). My command looks as follows:

gdal_translate -of MBTiles -ot Byte -strict -scale 0 255 bogota.tif bogota.mbtiles

The GeoTIFF image is successfully converted to MBTiles, and I am able to render it using QGIS. However, it appears that the result is somewhat compressed, or that the new image has lost some resolution. I have been experimenting with the -outsize option and trying to force it to 100% of the original size of the image, but with no success.

Is there a way to make sure that the result maintains the full resolution in the output?

Here are some screenshots to compare the results:
