ICVT has updated its desktop application JPEGmini for Mac. With JPEGmini for Mac users can quickly optimise full photo albums simply by dragging them onto the app. The optimised photos are claimed to retain the full quality and resolution of the original photos, while being much smaller in file size. The latest upgrade adds support for resolutions of up to 28 megapixels. “With the new 28-megapixel upgrade, JPEGmini for Mac can now optimize photos shot with 99 percent of the camera models available on the market today,” the company says. In a special introductory holiday offer, from now until 24th December, the full version of JPEGmini for Mac, which regularly retails for $19.99, is available for $9.99. In addition, ICVT is introducing JPEGmini Lite for Mac, a free version of JPEGmini for Mac that offers optimisation of up to 20 photos per day.
