Hello Everyone. I want to export my images to be a specific file size, in centimetres, and at 300 dpi. I don't see those options in the export window, and I haven't been able to figure out how to do it by changing the preferenes. Is it possible?

Export is intended for creating files for screen viewing where only pixel dimensions matter. The ppi value is irrelevant for screen viewing, so it's stripped out.

Use Save As or Save a Copy instead.

Create a duplicate of the original (Image > Duplicate), then go to Image > Image size to set dimensions in cm and the ppi.

I created a couple of scripts to add the PPI resolution metadata into exported JPEG files:

I think for this, your best option is to create an Action (https://helpx.adobe.com/photoshop/using/creating-actions.html) Once you've done so, you can use that action individually on any open image, or run it as a Batch Action (https://helpx.adobe.com/photoshop/using/processing-batch-files.html), or create a Droplet, so you can drag images to it (https://www.slrlounge.com/photoshop-tips-how-and-why-to-use-droplets/
