Hi Javier, As noted in my previous response, I was wrong about gdal_translate - it actually does transfer the XMP tags from the input to the output, as XMP tags. It is a subsequent call to gdalwarp that drops the XMP tags. I am running gdal 3.5.0

Without that option it should keep them. If I remember correctly, the XMP tags are copied as proper XMP, not as GDALMetadata, with TIFF files. An example with "gdalinfo -mdd all" for input and output may help. .___ ._ ..._ .. . ._. .___ .. __ . _. . __.. ... .... ._ .__ Entre dos pensamientos racionales hay infinitos pensamientos irracionales.

The output file contains many of the input EXIF tags, aggregated as the GDALMetadata tag, but not the XMP tags. Why does gdal_translate remove XMP tags - is there an option to preserve them?
