First, you just responded to a thread that's more than a year old.Don't listen to them and don't spend a penny you already spent a ton of dough on the best operating system on the planet. Open it with Preview, file, save as jpeg or whatever format you want, duh.
mkdir jpegs; sips -s format jpeg *.* --out jpgs
defaults write com.apple.screencapture type jpg
Wow - old thread.
For those who come to this later, open Terminal, cd to the directory containing your JPGs and type:
Code:mkdir pngs; sips -s format png *.* --out pngs
Mark,
Do you have Pixelmator? If not, you should. Then you can use automator with these steps:
1. Find Finder Items - Do a search to select all the .png images you want to transfer to jpeg
2. Get Selected Finder Items
3. Copy Finder Items - This will make sure you keep an original copy of all your .png images should anything go wrong.
4. Change Type of Images (This step Requires Pixelmator - I believe there is a free trial you can download but it is well worth the $).
Run the automator process and all your pictures are converted. I just tried this out and it converted about 40 png files to jpeg in 3 seconds.

Sorry to revive old thread but this is such a good tip. The problem though is it doesn't help newbie (like me) much so I recap it a bit.
1. Open Automator. Select Application and choose.
Now you choose the task from the left pane and drag it to action pane.
2. drag Get Specified Finder Items. Drag and drop all your files you want to convert.
3. drag Copy Finder Items. Create another folder for the converted pictures to go to.
4. drag Change Type of Images (Preview, you don't need Pixelmator) change format to JPEG, then Run.
5. Have a nice sip of beer and.. voila!
I'm trying to do this. I have many files in different folders that I want to be changed to jpgs. They all have the same name so I can't save them in one folder, I want them to be saved in their source folder i.e. where they came from. How is the best way to do this? Thanks guys.
This should beI realize this is an old thread, but I found it very useful and want to update it for others who search for it. If you want to convert png images to jpeg, you should use the following:
Code:mkdir jpegs; sips -s format jpeg *.* --out jpgs
mkdir jpegs; sips -s format jpeg *.* --out jpegs
