in iPhoto?

File -> Export

The Quality Setting is the one that has most effect on the size of the file.

has details of the options in the Export dialogue.

Which version of OS X are you using? In the newer systems versions you can hold down the option key ⌥ to change the "Duplicate" command ander "File" into "Save as". http://osxdaily.com/2012/08/27/enable-save-as-os-x-mountain-lion/

Select the photo(s) and export using the various quality and dimension options to achieve your goal

While LarryHN's meethod will work, it may take a bit of trial and error. That is you may have to try several different settings before you stumble upon the one that results in your desired file size. For more control, try this:

• Select the image in iPhoto and from the File menu, select <Export>
• From the <Kind> field, select <Original> then click <Export>
• In the next pop-up window, choose the Desktop as the location, and click "OK"
• Find your photo on the Desktop and Right Click - select <Open With> then <Preview>
• From Preview's <File> menu, select <Save As>
• From the <Format> field, select <JPEG>
• Look near the bottom of the Save As window and you will see the File Size; watch the file size change as you drag the Quality slider from left to right. When it says 2 MB, click Save.

There is no <Save As> under <File> when saving with Preview.

That's the problem with 5 year old threads, things change.

Does anyone have a suggestion, helpful hints?
