Hello there. A very strange situation happened after Photoshop's 22.5 upgrade. I usually work on 1080x1080 pixel files. When I saved these psd files as jpg with the "save a copy" command, they reached 12-13 mb in size. When I save the jpg from different applications, it becomes 500-600 kb. When I add a photo to PSD, the jpg file size becomes 12-13 mb each time. It somehow loads an extra 10mb into the jpg file. This doesn't happen if I save with "Save for web". I downgraded and reverted to version 22.4.2. Fixed.
I am using a mac mini with m1 processor.
Big sur 11.5.2
The likely culprit is Ancestors Metadata (but that would be unrelated to 22.5.0).
Yes, it seems like that's the problem.
Use the Script from the linked thread (in the first reply-post) to remove Ancestors Metadata.
Thank you for your help 🙂
Could you please provide one of the jpgs?
Is there a lot of text under File > File Info > Raw Data?
In older versions it was possible to view the excessive metadata, however, a few years back Adobe changed things:
