Photoshop export changes the dpi and photo size automatically when it shouldn't

I am on a iMAC.  Photoshop 24.1.1.  I save projects as PSD and then quick export as JPG.  Recently I noticed that my files are automatically reduced from 300pdi to 72dpi.  I'm not sure when this started but I did a Photoshop update recently.  There must be a place in Preferences where I can fix this, but I can't find it.  Would appreciate help as I don't want to send photos to be printed in 72dpi.  Right now I am saving as PSD in Photoshop and then opening the PSD in ON1 RAW (another photo editing program) so I can save as a JPG, but that is tedious.  Thanks.

They used Save As or Save a Copy (which preserves resolution/print size metadata) which is removed by design when using Export As/Quick Export which is intended for devices/screens where this metadata is irrelevant.

Hi @dianes98627266 how about simplifying this and just using "save as" where you can set Jpeg as format?

If this save is for anything other than an absolutely final file [right size, right crop] then you should avoid Jpeg as any subsequent cropping or size change will result in damaging recompression when saving. 

 

I hope this helps

You can use a Photoshop or Bridge script to quickly reassign a stripped PPI metadata value to existing JPEG files without decompression/recompression:

Thank you, everyone, for your guidance.  I clearly did not understand any of the technical terminology.  I use Photoshop, but know nothing about the technical aspects on how it works, just that it works (lol).  I kept trying things and I now see that I can "save as" in JPG format.  I'm able to see dpi and inches.  That's new and exactly what I want.  So I'm not going to stress about this any more.  Subject successfully closed.

    Just to explain what is really happening here: Export doesn't actually change to 72 ppi. What it does is to strip out the ppi metadata altogether. An exported file does not have a ppi at all; not 72, not 300, not anything. A ppi number is not relevant for screen/web/mobile, so it's removed.

     

    The 72 figure appears when the file is reopened into Photoshop, because it needs some ppi number for other reasons. So PS assigns 72 as a default number. In Microsoft applications the default is 96, so there the file will open as 96 ppi.

     

    Ppi is just an instruction for pixel density on paper. It is not a part of the image data. The file is just pixels, and as long as the pixels don't change, the file doesn't change.

      Hmmm...I need to figure out what you're saying as I don't really understand it.  How will I ever know the true size in inches before ordering prints online?  Or if I want to change the JPG size?  I may have to do more work in ON1RAW.  That's too bad as I've been using Photoshop for more than 15 years and am comfortable with it.

      Hi @dianes98627266 What problem did enabling Save As not fix? Save as maintains your Image Size as is (you can always double check in Image Size).

      Kevin is correct - quick export is for web so it's changing your settings. You need to do a save as or you can run a batch through Bridge if you have a bunch at a time.

      Hi @dianes98627266 double check your files - if you are using Save for Web, they convert to 72 ppi, but the pixel dimensions are the same (your w&h are almost tripled). If you go back to Image Size and convert it will be the same.

        Thank you for your quick response.  I am not choosing save to the web.  What you mention, dpi reducing and size increasing is what is happening.  I've been using "quick export" for years ever since Photoshop changed the saving method.  I checked photos from last summer and this was happening but I didn't realize it (hundreds of vacation photos).  In looking at my photos from 2019, the JPGs are all 300dpi.  I can't use "save as" because JPG is not one of the options.  Also, I like to size my JPG images by inches but now I'm only seeing save as pixels with no other options.

        Hi @dianes98627266 go to Photoshop/File Handling and check "Enable Legacy Save As". That will address your save as issue.
