iWatermark Pro is a Mac application that was designed for professional photographers as well as for novices who wish to digitally sign their pictures.
The utility provides you with many output profiles, works with various photo formats, and gives you access to several image editing features. You can import as many pictures as you like, rename and resize the input files if necessary, and even choose which metadata to transfer from the original files to the final images.
For a Mac application, iWatermark Pro looks a bit "crowded". It shows an interface filled with a large amount of options that some users with little computer experience might find difficult to handle.
Nevertheless, the program immediately offers you the quality results you need and doesn't slow down the performance of your Mac while watermarking the input files.
With that being said, you should try this app if you're looking for an efficient solution for watermarking pictures. Plus, the program comes with a reasonable price.
