The creators of JPEGmini, the popular photo-resizing application and plug-in for Lightroom and Photoshop, have announced that the plug-in is now available for Capture One as well. This brings the remarkable compression features of JPEGmini directly into the application, making it easier and more efficient for photographers using Capture One to create images at vastly reduced sizes.
If you haven't ever used JPEGmini, you should definitely check it out. It's one of my favorite applications, as it can reduce the size of JPEG images up to about 80% with no real discernible loss of quality. This makes it particularly useful for portfolio websites (especially as more and more users will visit your work on mobile devices in the future), where you of course want the quality of your images to maintained while reducing loading times as much as possible, which also increases one's Google ranking. The process is entirely automated, and now that Capture One allows for third party plug-ins, users can easily and quickly reduce the file sizes of their JPEGs from within the program. The plug-in supports images of up to 128 megapixels, multicore processing, and batch resizing. I personally can't recommend the program enough; I definitely suggest checking it out.
