Every Mac graphic app of any quality will compress JPEG photos with ease. That means a 5 megabyte JPEG file can easily be compressed by 60-percent or so to barely 500k in size.
That kind of image compression saves disk space, makes it faster to send photos by email, and makes images and photos faster to download to a browser when they’re embedded in a web page.
The only problem with compressing JPEG images is quality. The more the compression, the more artifacts and blurs show up in the compressed image.
JPEGmini is a Mac app which lets you compress images and photos, reducing their size by up to five times or more, while keeping the original quality.
Here’s a couple of sample images.
The strawberries photo was reduced over three times without notable loss of quality (and further compressed in the web page).
The following image was reduced over eight times in size with nominal loss of quality (and, again, further compressed in the web page).
Overall, compressing images and photos using JPEGmini resulted in a much smaller file size, with hardly any loss of image quality.
Anyone who compresses images or photos knows about quality loss when using compression such as JPEG. JPEGmini uses a proprietary algorithm to keep quality high, while reducing file size.
Simply drag and drop a photo or folder of photos onto JPEGmini and wait for the results. Images and photos compare nicely with similar compression and results when using Adobe’s Photoshop or Firefox (at a substantially lower price).
There are a few caveats, though. JPEGmini isn’t free. And there’s a limit on file size and resolution (oddly, 17 megapixels). It’s a Mac App Store app so there’s no trial version, but an option to try compressing a photo online.
