PhotoBulk: Tom's Mac Software Pick

Batch Image Processor Without the High Cost

Eltima Software

PhotoBulk, from our friends at Eltima Software, is one of those specialized apps that concentrate on doing just a few things quite well. In this case, PhotoBulk is a batch image processor that allows you to add watermarks, resize and optimize photos, convert to various file types, and rename images, all with a simple drag-and-drop interface.


  • Supports popular graphics formats, including JPEG, PNG, GIF, BMP, and TIFF.
  • Add text or image-based watermarks.
  • Resize images based on percentage, width, height, or max size.
  • Optimize JPEG and PNG images.
  • Rename using sequential prefix or suffix.
  • Supports presets for applying your commonly used edits.


  • Can’t chain effects.

PhotoBulk is an easy-to-use batch processor that allows you to add watermarks, and resize, optimize, and rename your images. It's very easy to use, very quick and allows you to create presets for those image manipulations you use most often. It also offers previews, to ensure that the changes you're making are really what you want.

PhotoBulk doesn't make changes to the originals; instead, it saves changes in a folder you select, allowing you to keep the originals and edits separately.

Installing PhotoBulk

PhotoBulk doesn't require an installer; simply drag the app to your Applications folder and it's ready to go. The same is true if you decide PhotoBulk is not for you; simply drag the app to the trash, empty the trash, and PhotoBulk is removed.

Using PhotoBulk

PhotoBulk is a compact app with a single window that resizes to fit the imaging tools you select to use on your photos. PhotoBulk has a large drop zone where you drag all the images to which you wish to make bulk changes.

I didn’t notice a way to delete an image added accidentally, but it doesn’t really hurt anything since the originals remain untouched. The only consequence is an unwanted processed image in the output, but it's simple to delete it.

Just below the drop zone is a toolbar containing text buttons for each of the effects you can add to an image; the effects include Watermark, Resize, Optimize, and Rename. There's also a seeing eye icon, which allows you to see a preview of the changes that will occur.

When you select an effect, the window will expand to show the tools for making the selected changes.


This feature allows you to add an image, text, date, and timestamp, or script. The script adds any text you enter repeatedly across your image. It’s a good way to add text, such as Sample, that allows someone to see the quality of your image, but makes it pretty much useless if they wish to abscond with your work.

When you choose an image to be used for a watermark, you can select the image to add, the size to use, the location for the image, the watermark's rotation, and its opacity.

For the text options, including date stamp, you can select the font, size, and style for the text and date stamp options, along with location, rotation, and opacity. =


You can resize an image by height, width, percentage, free size, and max size. You can also choose not to apply resize effects to smaller images that would require enlarging to meet the resize specifications.

The Resize feature can be especially helpful if you have an image size requirement. For instance, I like to ensure that all my images are no larger than 1000 pixels tall by 1500 pixels wide. I can use the Resize feature to ensure that any image bigger than those dimensions is resized proportionately to fit within them; by selecting the Don’t Enlarge option, I can ensure that images that are already smaller aren't made to fit.


The Optimize options are restricted to images that you'll save as JPEGs or PNGs. You can set the compression rate for the saved image, from maximum to minimum and anywhere in between, using the compression slider. But keep in mind that while in many cases, using compression can speed up how fast an image loads, it can also lead to a loss in image quality.


The rename feature lets you select a base name that you can then add sequential digits to, either as a prefix or suffix. For instance, if you set the base name to Yosemite, the batch-processed images might be named Yosemite-1, Yosemite-2, Yosemite-3, and so on.


You may have noticed that although I mentioned that PhotoBulk can convert between various graphics formats, there's no option within the app to perform this task. Instead, the conversion occurs when you save the output of the batch processor. You can select JPEG, PNG, GIF, BMP, or TIFF as the format for the saved images.

Final Thoughts

PhotoBulk doesn't try to be a large, complex image batch processor; instead, it focuses its attention on just a few image manipulation processes that many of us need to perform.

At $5.99, PhotoBulk is a steal, and I can easily recommend it for anyone who wants to add watermarks to their images, needs to resize photos, convert between popular image formats, or just trim down a bit of photo fat with the image compressor.

PhotoBulk is $5.99. A demo is available.
