1. Re: Pshop CC -- saving JPG & PNG file size bloat
Curt Y Jul 15, 2013 5:35 PM (in response to genericAndy)If you use quality 12 on a jpg save it will bloat the size, but not sure about this much. Quality 10 is all you need.
You need to dig deeper in how you are saving, as I doubt that file save has changed for decades.

Noel Carboni Jul 15, 2013 6:01 PM (in response to genericAndy)Haven't had a PNG or JPG go wacky here in that way so far...
I think the issue is revealed by looking in File - File Info in the Raw Data section. I don't know why, but there are a huge number of <rdf:li> XML elements showing up there with hex values in them. I don't know what that means, exactly, but I believe the accumulation of that metadata explains the size increase.
Do any of the terms you see in the raw metadata mean anything to you? Do you have 3rd party plug-ins that could be responsible for this?

genericAndy Jul 15, 2013 7:56 PM (in response to Noel Carboni)@noel No addons or 3rd party plugins.
Thanks for at least figuring out what it is. Now if anyone out there can help me figure what is causing the data bloat, Id be really appreciative.
@curt -- even with quality 12, an image this small should be no more than maybe 50k-100k under an extreme circumstance. I did test that potential theory before. Setting the quality to 1 stll made the image 1+mb

Chris Cox Jul 15, 2013 8:09 PM (in response to genericAndy)It's metadata, in the XMP packet. Most of it is document ancestry info, based on previous versions, placed files, pasted files, etc. Printing data could also increase the file size, paths, etc.
SFW doesn't include all the metadata by default, so saves a smaller file.
So, no bug, no bloat, just failing to understand what all you're saving.

That's what Save For Web is for.

trshaner Jul 20, 2013 4:35 PM (in response to station_two)I had a similar problem at this post:

I created a new PS Preferences file and the bloat is gone. In my case all 'New Files' created in PS 64 bit were being appended with a Costco printer profile, adding about 1.4 MB to the file size.
