What difficulty do you face in doing this? Is it that you don't know how, or that the results you get aren't what you expect?

What version of Photoshop do you have?

I am using photoshop 7 version 6.1.   I have successfully completed this in the past a couple of times but now I can not remember how to do it.

I still have a copy of Photoshop 7, and I checked: it had this feature as well as today's versions.

File > Save as.

BMP format.

Advanced button.

Choose the format you need.

I have tried this but it only allows me to save this as a .psd,.pdd or .raw or.tiff.    the file I am starting with is a .png file

You have the image in 16 bit per channel mode. This is very specialist (for Photoshop 7) high definition colour. You must use Image > Mode to make it 8 bit per channel.

I am trying to make a "splash Screen" for a Radio.  the Requirements for that is 16 bit

I understand your worry, but it is misplaced. You a trying to make a low definition colour image but you have high definition colour.

The mode 16 bit colour in Photoshop is 16 + 16 + 16 = 48 bits.

You want 5+6+5 = 16 bits.

So you currently have three times too much detail.

So reduce it to Photoshop 8 bit (which is 8 + 8 + 8 = 24 bits) and allow the save as to reduce it more.

In Post #0 you said "16 bits per pixel RGB565. The source is probably 24 bits per pixel

(not 48 bits per pixel). Any RGB 24 bits per pixel image can be saved immediately as
