If you're gonna watermark one image, you're probably going to watermark a bunch.

Tedious tasks like resizing and watermarking photos are just begging for a batch processor. Newcomer Convert from CF/X can handle that. You can resize photos by height and width, in pixels or by a set percentage, or crop photos to a specific set of dimensions.

But we wish Convert had more features for the price. At press time the “special introductory price” was $19.99 (half off from $39.99), but the app doesn’t do much more than batch processors that cost much less. QuickScale, for example, is just $5.99 in the Mac App Store.

While we appreciated Convert’s ability to create PDFs, a feature most batch processors lack, we just don’t think PDF creation and batch image processing really go hand in hand. (How often does anyone create a PDF entirely of photos?) Convert can access your iPhoto library, but this feature is so slow that we wound up exporting photos from iPhoto to a new folder before batch processing them.

Convert is a solid resizer, but it doesn’t let users selectively crop based on photo orientation. You could load images that are either all in landscape or all in portrait, but we’d like to see Convert handle this within the app. More disappointing is the lack of support for custom watermarks. You can specify a watermark’s text and opacity, but not its location, and you can’t use a custom image or logo. And not to be overly shallow, but we also found the app utterly unattractive.

The bottom line. Convert batch resizes images--and fast. We’re sure some pros will love the app’s ability to create PDFs and HTML catalogs of their images. And did we mention it’s fast? But for an app at this price point, targeted at pros, we long for a few more core features and a more aesthetically pleasing interface.
