Pixa for Mac is an image organizer with some great tools for collecting web inspiration, as well as creating new projects and quickly exporting to fit your workflow.
The Quick Export feature lets you create export templates to fit specific image formats and dimensions your workflow needs. For example, I have a “PNG 512px” template that exports as PNGs at 512 pixels wide, and another basic “JPG 50%” that exports as JPGs at 50 percent of their original dimensions. Then I can click one or 100 images, click one of my export templates, and Pixa goes to work.
Pixa also has useful project and file template tools. You can create a new project in your library for organizing files, then use File > New File From Template and a couple of built-in PSD projects to get started, such as designing icons for a new app and website or a basic 960 pixel website grid. You can then edit those layered PSD files in your app of choice and save them back to Pixa. As you might expect, you can right-click any file in your Pixa library and choose “Save as Template” to start creating your own library of templates for new projects.
When you factor in “Live Folders” feature that allows it to watch for files you toss into Finder folders (yes, even Dropbox folders), Pixa becomes a really powerful image, inspiration, and project organizer. It’s great for graphic artists or people like me who simply need an app in addition to iPhoto or Aperture/Lightroom to organize all those other images.
Pixa is available in the Mac App Store.
