Convert JPG to PNG

If the files are in iPhoto, you can select File Export and then Export them as PNG.

You can make an icon from a jpg using Preview.

Open the file in Preview. Press Command-A (Select All in the File menu). Then prss Command-C (Copy).

Do a Get Info on the file or folder you want to place the picture on as an icon. Select the icon of the item in the upper left of the Get Info window, by clicking it.

Then press Command-V (Paste). The picture will be placed as the icon for the item.

Using Mavericks and viewing a JPEG in Preview, when I choose "Export..." from the File menu I get splash screen; in that screen, if I click the "format" pulldown I get several selections, among which is PNG -

I can get to the same place by opening the File menu, then pressing and holding down the Option key. Doing this changes the "Duplicate" item to "Save As..."; selecting that brings up the same splash screen (with the minor change of "Export As" being changed to "Save As").

Question? I use EXPORT, but I only get three file format choices: JPG TFF PDF. Someone suggested that I hit the OPTION key to pull up other formats, but that doesn't do anything as far as I can tell. I'm trying to get from a jpg to a png. Any suggestions?

I use this website. It's free, easy and fast.

This website also does sound and video conversion as well as images. As a freelance designer and developer I use them all the time and it's FREE! 🙂

Open the document in Preview, choose Export from the File menu, and specify PNG as the format.
