changing screenshots from .png. to .jpg

[colli]

Hi
I was wondering how to change my screenshots, (that have been downloaded onto my iphoto from my iphone) from .png to .jpg (both photos on iphoto currently and future screenshots). I have a Mac OX 10.6.8
Thanks!

I don't know if they can be "converted" in place, but you can sure create a jpg from a png by using the Export option.

Open the images in Preview (which may or may not be the default application), click Save As, and you should see in the dialogue window the Format option with which you can change .png to .jpg.

You want to change it on the phone? Don't know if you can do that.
Then again, I don't have an iPhone.

Thank you.
I'm in iphoto and trying to change the screen shots that were downloaded on my iphone in .png to .jpg
I tried use "save as" in preview to change the format but it's greyed out.

Try holding down your "option" key when you select "Save As".

Or use Export.

I have used Sharpshooter for years for screenshots and location for file save and file type all of which can be set in prefs.
In most Apple applications, as cradom mentions above, will cater for after the event format change in file types. Of course what has been changed in El Crapitan is out of my area of knowledge.
