Photoshop 2020, on a windows 10 pro computer won't export full size JPRGs

[joecos55]

I don't know what's going on, this seemed to just start I have some files I worked on I want to export or save as a full-size JPG (files are 17 to 24 MB in size).

No matter what I do save, save as, export as, even the old save for web, my files export out as 750 to 800 kb.  I need to send these to a printer.  I have done this in the past with no issues.  Any Thoughts

Thank you in advanced

The jpeg file format uses very aggressive data compression to reduce file size on disk. It is important to understand that a file format is a storage container. An open image does not have a file format. The data are packaged for storage on disk, and in the case of jpeg, those data are compressed down to 2 -10% of original storage size.

When you reopen a jpeg it is decompressed back to original size. Once open, it is no longer a jpeg, just an image like any other.

Jpeg compression is destructive, cumulative and non-reversible, and the file degraded with every new save. Image size in pixels is the same, but artifacts build up and detail is gradually lost.

I understand about jpeg compression, but this work flow has worked for me for years.  Its weird that I can't even get a 1mb jpeg out of a 24 mg layered file in photoshop.It has to be a setting or something I a overlooking

thanks

DUH  I knew it was something stupid, I just went back in and looked at the export for web window and saw that optimized was selected, I switched to original and I get a 13mb file .  Thanks for responding.  I knew it had to be something obvious I was overlooking.  week 8 of staying inside is playing mind tricks.

Thanks again
