Any Mac user who takes a lot of photographs runs into the same problems. Renaming, converting, color adjustments, watermarks, and photo file management are just a few of the issues we face. iPhoto might be good to store a large number of photos but it’s not much for batching— making adjustments to many photos at one time.
When it comes to batching changes to many photos at once Mac users have a few choices, starting with individual apps that do one thing. One app adds a watermark, while another converts to different file formats, while another changes color or file size.
What I’ve always preferred is one app that does most of the batching. While not free EasyBatchPhoto might be the bargain you’ve looked for. As the name implies, it applies a number of changes to a large number of photos.
The list of batch adjustments you can make to dozens, hundreds, or even thousands of photos is lengthy.
EasyBatchPhoto adds a watermark, fits photos to specific size, adjusts quality, converts between file formats, rotates images, and a few more useful settings, including setting the file creation date and outputting photos to a different location.
It reads most Mac graphic file formats, and converts to JPEG, PNG, and TIFF, including true lossless JPG. And, it features on-the-fly photo renaming options which can be very handy when dealing with hundreds of photos.
There are a number of Mac apps which doe some of what EasyBatchPhoto does, but not one I can find that does it all. Maybe that’s why it’s been around a long time.
The only issue I’ve run into after years of use is watermarking, where some images don’t render correctly. Sometimes simply adjusting the watermark eliminates the problem, but not always.
