Hello

I make images   1080/1920 at 300ppi and the size after saving always was under 1 mega.

All of a sudden,the same kind of images are being saved at over 9 MB. I ont know what's happening,I have uninstalle and reinstalled ps but it still persist.

Please help

If the jpg or png is much smaller when using File > Export > Save for Web then the issue is likely Ancestors Metadata. 

And you can do a Forum search to find the Script to remove it.
