convert png to jpg

Converting a PNG file to JPG is really easy in Mac OS X, here are the steps:

* Launch the origin PNG file within Preview
* Navigate to the File menu and down to ‘Save As’
* Select “JPG” under the ‘Format’ drop down list
* Click “OK”

Your PNG file now has been converted and saved as a JPG file to the location you specified! If you want you can go back and delete the origin PNG file. Naturally you could reverse the process and save a JPG file as a PNG file to do the opposite conversion.

    Anyone have a clue how to “batch convert” .PNG to .JPG in Photoshop CS5 on a Mac Pro Dual? I have over 500 grabs (PNGs) for a project I must do that are taking up a ton of space and I can’t work with them as PNGs. JPEGs will be fine for my purposes. I know how to do batch conversions, do it all the time, but nothing’s happening when I try it with the PNGs. They just won’t convert in batch.

    Do I have to do them one by one? You gotta be kidding me. Can’t find any help, forums or tutorials online. I can’t be the only one facing this challenge.

    Please feel free to write me directly if anyone can help —

    Thank you very much,

    Re: OS X Lion – use ‘export’ instead of ‘Save As’

    I have “upgraded” to lion and have received some png attachments in an e-mail. My wife can read them with her iPad, but all the iMac can see is an icon. I have gone through the steps using “export” and it “does its thing” and appears to be converting it to a jpg, but the result is still the same icon, not a readable document.

    Re: Converting a JPEG to a PNG …

    “Save For Web & Devices”, NOT “Save As”, in PS CS5 will provide the option(s) for saving as a PNG-8 or a PNG-24.
