This question already has an answer here:
I have a PDF file which was saved from Photoshop, that I need to edit. File size is 30 MB.
It opens in Photoshop directly, without an Import prompt window, so it was probably saved from Photoshop originally.
Then, after all the edits, I merge visible layers, so that the file would have roughly the same amount of information as before.
After it was saved, file size increased to 150MB, 5 times the original size. Why? I haven't used "Save As" command so shouldn't it be saved with original settings and have roughly same size?
I compared the initial file and the edited file dimensions in mm, DPI and pixel dimensions, with Pitstop Inspect tool - they are the EXACT same! The only thing which was changed is "Compressed file size" went from 19% to 37% of original size - what's up with that? What compression level does Photoshop use on regular "Save" command, how do I see/change it?
