We have found 2 software records in our database eligible for .psd to .pxd file format conversion.
Pixlr web app is best choice for .pxd files, but it now saves to .pxz files by default and no longer offers saving to the original PXD format. Thus, if you for some reason need the picture in that particular format, you have to rely on 3rd party alternatives that still support the previously used .pxd files.
