ThumbsUp for Mac makes lower resolution versions of your images with various optional settings. The software comes free of charge and employs an intuitive mode of operation: dragging and dropping images on top of the app's icon in order to initiate the thumbnail generation. Other noteworthy features include custom names for the newly generated files, multiple supported formats, and a fine-grained control over image resolution and quality.
ThumbsUp for Mac can be used in one of two ways: by dropping image files on top of the app's icon or by Option-clicking the image selection and choosing the software from the Open With menu. Launching the app, itself, reveals no main window, just a preferences panel. There you can choose one of six popular output formats and set options like name extensions, icon generation, and image resolution and quality levels. When it comes to size, you can either set pixel limits or scale. And you also have the ability to strike a balance between image quality and compression as well as set sharpening and anti-aliasing levels. While testing with all options active and a 20 percent scaling, the app needed about ten seconds to convert 80 images.
If you'd like to quickly create smaller images that load faster, ThumbsUp for Mac has you covered. It provides you with all the options you require, while its intuitive and unobtrusive mode of operation will make it a joy to use. It's a fast, easy-to-use, and helpful app.
