I have to save my images as png-8, 300ppp, with Photoshop CS6 and always works good. But today, the same image yesterday was 250kb, today is 1.1MB, without making any change. Can somebody help me, please? I work on Mac.
Thanks for your help.

2Hi Eva! What do you mean "the same image yesterday was 250kb"? Because one of your images here says "copia", so it's a different file. Maybe the second one was saved in PNG-24 instead of PNG-8?– YiselaMay 5, 2014 at 3:29

Yisela, I can see the png-8 and png-24 if I save for web devices, but if I save from the File - Save and select the png option, how can I know the png-number? EDIT: I take off the copy option and just go down 0.1MB :(– EvaMay 5, 2014 at 3:52

The two images you posted don't seem to be the ones that are described:J2kcw.png is 67018 bytes 454x346, and F1276.png is 54590 bytes, 475x294. So, if they are actually scaled-down copies of your two images, it's not easy to diagnose the problem. Can you post the actual problematic images?– Glenn Randers-PehrsonMay 5, 2014 at 16:35

Glen, yes I can, but they are huge and I don't know if I can do it here. 1 of them is a single curved line size 3579 × 715 and it's a 1,2 MB png very heavy. Here it is.– EvaMay 6, 2014 at 9:11

1"Here it is." -- no, that's a 42-kilobyte JPEG. How about just running "pngcheck -v file.png" and see if that tells us anything useful, compared to the result of "pngcheck -v file.png" for the smaller one?– Glenn Randers-PehrsonMay 6, 2014 at 19:37

you might have saved the first file as - "save for web" and the next file as normal "save as"......so that can make difference in file size.
Probably try saving the files as - "save for web" with png-8 extension.
Hope it was helpful

Thanks, but the 65% of my job is save images as png, 300dpi. So, I know what these means. Maybe I didn't explain myself very well (English isn't my born language). If I take any other png image and re-saved, this one is three or four times bigger. I've tried with my own images, net images, purchases, and everytime if I save it again, they are huge. Happens with new draw images too. This never happened to me before. The only change I did in the last days it was installing more RAM memory to my MAC, but this is not a reason for the problem. But thank you anyway.– EvaMay 5, 2014 at 6:08
