hi all
thanks for all the reply. in my case i have not uploaded the to google photo site yet. i was just trying the google photo app on my android phone to open pef files.
after a bit more investigation the smaller files (the output from google photo app "save copy") are actually jpeg files. what confused me was the file name still uses the .PEF file extenstion.
as shown below comparison of the metadata. interestingly DNG files do not behave this way with the google photo app, as the output is using jpg file extension.
original file :
IMGP7785.PEF: TIFF image data, big-endian, direntries=21, height=0, bps=12, compression=(unknown 0xffff), PhotometricIntepretation=(unknown=0x8023), manufacturer=PENTAX , model=PENTAX K-x , orientation=upper-left, width=0

Hi all
i am trying to decide if google photo is good enough for my personal raw processing. i find that it reduces the pef file size and i am not sure what is happening.
i seem to be able to open pef files and make adjustments to the image and then i do a "save copy" and then i check the copy all seems ok except it was 10x smaller.
anybody knows what is happening ther? googling did not give me much info on how it handles raw files so decided to ask here in case someone else does.
regards
prysm
