Photoshop PNG not saving at correct size and resolution

First, I have read many previous posts and am still not able to resolve my issue.

I am hoping someone can help me - in an Answers-for-Dummies type fashion, please. I am pretty desperate with over 1,000 digital download products I need to save as PNG & JPG at 300 ppi and 4" x 6" dimensions. 

I have included all the screenshots you might need so I won't go into much detail here. I just need to say that while I do understand the basics of pixels per inch, I am obviously not understanding why 300ppi files when saved as PNG files always result in 72ppi files with an absurdly high number of inches - in this case 16 x 25 !!

I am selling these products and need to offer 300 ppi (dpi) high res jpg and png images. While I do understand that png images are used for the web which would justify PS auto changing the ppi to 72, I am really worried that my customers may print the PNG file and it would actually print out at over 16 x 25 inches!

My customers will likely be using these images for web and/or print. Some will need transparent backgrounds, others will be fine with flattened white backgrounds. Files were created in CMYK and saved as original psd backups. The mode was changed to RGB (Merging Layers) before saving as jpg and png.

** NOTE ** I do apologize for the last screenshot (which is actually a 2nd question). I just noticed that the jpg I saved at the highest quality (10) - File > Save As > JPG > Maximum Quality - is less than 500kb. Is that not extremely low for a 4 x 6 300dpi image?

Any help and/or reassurance would be much appreciated.

Thank You for your time.


























Sorry for this extra screenshot (which is actually a 2nd question). I just noticed that the high res 10 max quality jpg I saved is less than 500kb which is quite low for I what I need.





Thanks!

I recommend trying Lightroom CC Classic, with a png plugin. Exporting multiple images in multiple pre-defined formats is a thing it does really well and quickly.
Maybe this? https://www.naturettl.com/export-png-files-lightroom/

But you can set up export presets in Lighroom, then just select a big batch of images and pump them through each export type. They'll even export each batch in parallel.

Another advantage is you can make "virtual copies" of an image with different crops or filters applied and it will save only as metadata, not a whole new psd. Then you can have, say, a 2:3 ratio and a 4:5 ratio crop of the same image in color and black and white each, but one source file on disk.

There is apparently a bug in png export where the resolution is not always properly saved to metadata. Try Image Processor Pro to see if that works, you can specify output ppi resolution.

OK. So I installed Lightroom Classic and the Magic Export Plugin as Max suggested. Thanks Max! I imported a copy of the original psd and then exported as a 300dpi png using the Magic Export plugin. I then opened the new png file in PS and YAY it is now 4 x 6 and 300ppi as I had hoped.

I then noticed in Bridge that the metadata for the new png still says 16 x 25 inches and 72ppi. You can see from the screenshots below this is clearly not correct. I can only assume at this point that Bridge is also buggy.  As long as I have a 4x6 300ppi png file - I'm a happy camper!

All I can say now besides thanks to Photoshop Family, Max & David (I will be trying Image Processor Pro soon) is Shame on you Adobe for not allowing us to save 300ppi png files from PS and for not fixing the metadata issue in Bridge. I'm sure I must not be the only person who has been tortured by all of this.

Thanks!
